Why High GDUs Aren’t Guaranteeing Quick Emergence This Year

Tue, 12 May 2026 20:35:00 GMT

While farmers keep a close eye on the thermometer and their favorite weather app during planting season, Phil Long says the most important metric right now might be the one they can’t see: the temperature beneath the soil surface.

Long, a regional agronomist with Liqui-Grow, says growers in north-central Iowa are reporting sluggish emergence for corn and soybeans. That’s despite the fact the region accumulated roughly 197 Growing Degree Units (GDUs) from April 10 to May 1, outpacing the 30-year average of 121 GDUs.

“It takes about 130 or so GDUs to get corn or beans out of the ground,” says Iowa-based Long. “So why aren’t more crops emerged?”

The discrepancy, he contends, lies in the difference between air GDUs and soil GDUs. While air temperatures are important, seed reacts almost totally to the heat of the soil surrounding it. For a seed to germinate and push through the soil surface, it requires consistent warmth that hasn’t materialized during recent chilly conditions in some areas.

“What’s most important to the corn and beans out there in the ground is soil GDUs,” Long says. “Even corn up to V6 is regulated primarily off the heat in the ground.”

Why Some Crops Have ‘Just Sat There’

The formula for calculating GDUs relies on a base temperature of 50 degrees Fahrenheit and a ceiling of 86 degrees. When nighttime temperatures dip into the 30s, as they have recently in Iowa and parts of the Eastern Corn Belt, the soil temperature can linger in the 40s and 50s. At those levels, the “heat engine” for the seed essentially stalls.

“We’re not getting that soil temperature up there very far,” Long explains. “That does not stack up GDUs very quickly.”

Long notes that along with the chilly weather conditions, two additional factors can act as “buffers” against soil warming: crop residue and cloud cover.

While heavy residue is often a benefit in the heat of July, it can act as an insulator in the spring, preventing the sun from reaching the soil. In some cases, high-residue fields can see a 50% reduction in GDU accumulation compared to conventionally tilled ground, Long notes.

Furthermore, a stretch of overcast days will rob the soil of solar radiation.

“If there’s heavy cloud cover, that can reduce solar radiation by 80%,” Long says. He explains that even on a cool 55-degree day, direct sunlight can push soil temperatures much higher. But persistent clouds have kept the ground locked in a cool cycle.

As planting continues into the heart of May, Long advises farmers to look beyond the air temperature and keep in mind the micro-climate of the seedbed as they plant.

“Although we’re ahead in terms of air temperature GDUs for this year compared to the ‘average’ year, we’re probably behind in terms of those seeds sitting in the ground,” Long says. “That soil GDU is a big factor when it comes to getting crops out of the ground.”

From 60 to 600 Bu. Per Acre: Is 1,000-Bushel-Corn Next?

Tue, 28 Apr 2026 12:23:13 GMT

Across parts of the South, farmers are sitting on the sidelines this spring, not not because fields are too wet, but because they’re too dry to plant. With dust blowing and soil moisture in short supply, planters are parked as growers wait for rain, a stark reversal of the delays they’re more accustomed to and a reminder that in agriculture, timing is everything.

“We’ve been dry all season so far and we actually stopped planting because we’ve been so dry. Can’t just get the planter in the ground,” says David Hula, a farmer in Charles City, Virginia.

After six weeks of high winds and little to no rainfall, Hula says the conditions are unlike anything he’s experienced.

“I talked to my cousin who’s a decade older than I am, and this is the driest he’s ever seen. And I’ve talked to my agronomist, he says we’re the third or fourth driest on record since 1875 for this time of year. So this is uncharted territory for me right now,” he says.

While part of his crop remains unplanted, Hula is encouraged by what’s already in the ground.

“Everything that we’ve planted so far, I feel really good. Emergence has been spot on. Even their soybeans came up good,” Hula says. “We waited till things warmed up, you know, I’m very diligent and patient about that. And all that corn has come up awesome.”

Waiting Without Sacrificing Yield

With roughly 40 percent of his crop planted, Hula is now watching the skies and waiting for moisture before continuing.

“So the portion that you’re waiting on moisture to be able to plant at this point, you don’t feel like you’re sacrificing yield by waiting. You feel like you’re protecting yield,” we asked Hula.

“Oftentimes growers think, well, it’s too wet to plant or it’s been too cold. So they’re the things that you want to wait for. Well, we still, because we’re not late yet, we still want to make sure we get uniform emergence. That’s the key, that’s the first box every grower needs to be paying attention to,” Hula says.

He says with sporadic pockets of moisture within the dry soils, he says conditions are conducive for poor or uneven emergency when planting into drought conditions, and it’s a risk he’s not willing to take.

Hula’s World Corn Yield Record

That focus on emergence has paid off. Hula holds the world record for corn yield, producing more than 623 bu. per acre , a benchmark that underscores his disciplined approach. He says the year he grew that new record yield was in 2023, and it was a crop that wasn’t planted early.

“That was towards the end of May. I mean end of April, first part of May, but it seems like our highest yield stuff comes when we plant later,” Hula says. “And that is again, we’re checking that box of the crop coming up uniformly. And that’s the one thing I don’t know that growers really understand the importance of that. And once they do it and see it, they’ll say, you know, it might have been worth holding off for one week.”

A Seed Legacy That Dates Back a Century

The hybrid behind that record yield — Pioneer P14830VYHR — carries a legacy that stretches back a century.

“One of the wonderful stories of Pioneer is actually the introduction of Raymond Baker,” says Dean Podlich, who leads R&D digital solutions at Corteva Agriscience, during Pioneer’s 100th anniversary celebration last week. “Raymond Baker was a college student. In 1926, he met Henry Wallace at an event at Iowa State. He was very interested in hybrid corn, and he said, I would like to get involved with hybrid corn to Henry Wallace. Together, they actually put an entry into the Iowa corn yield test, and they actually won that contest in 1927. This is actually a certificate from 1927. We actually have the ribbon.”

Podlich says that early success helped launch hybrid corn into mainstream agriculture.

“Raymond Baker actually quit college in 1928, he joined the company as a farm hand, and he would go on to lead the breeding organization for more than 40 years, especially after Henry Wallace went to Washington. And so there’s a huge amount of history that is the start of our research engine,” he says.

100 Years of Yield: 60 to 600 Bu. Per Acre

One of the inbreds behind modern hybrids, known as Baker’s Inbred or B164, still plays a role today.

“What’s fascinating is that David Hula had a world record with 623 bushels a couple of years ago. We can trace the family tree of the genetics behind that hybrid all the way back to Baker’s Inbred itself,” Podlich says.

Two kernels, 100 years apart: One yielded 60 bushels per acre in 1927; the other topped 623. They look nearly identical on the outside, but a century of genetic innovation separates them under the hood.

To the eye, seeds from then and now look nearly identical. But the difference in performance tells a much larger story, from the seed yielding roughly 60 bushels per acre a century ago to more Hula’s record yield of more than 600 bu. per acre today.

“The thing that’s very striking as you look at these two sets of seeds is how similar they are. It’s really hard to see any difference, but under the hood these things are really, really different,” Podlich says. “You have 100 years of selection, 100 years of breeding, 100 years of improved agronomics, improved drought tolerance, and higher genetic potential. This one also has biotech traits in it that help increase yield, protect that yield from insects, and provide herbicide tolerance. So this is what’s so remarkable.”

Is 1,000 Bu. Per Acre Yield Next?

Even with record-setting yields already achieved, Hula believes the ceiling is still far off.

“My late granddad was the first one to break a hundred in the area. My dad, a couple hundred bushels, and we got three, four or five, and where we are now. And that has been a really steep incline. So I’m excited about where things are in the future. I have no clue what the yield potential is,” Hula says.

“Somebody was asking me what the yield potential is today. When you open up the bag, I would say it’s in excess of a thousand bushels. If that’s the case, we’re poor farmers. You know, here the country’s only averaging 180-some bushels, and if the potential is truly that, we’ve got a long way to go. But then can you imagine what price corn would be,” he says.

During Pioneer’s 100th anniversary last week, Sam Eathington, the Chief Technology Officer (CTO) for Pioneer, gave remarks to those in attendance. In his address, he not only looked at the past, but also gave a glimpse into the future. He says in 50 years when Pioneer is celebrating it’s 150th anniversary, he think it’s possible agriculture will have national average corn yield of 300 bu. per acre and record yields reaching 1,000 bu. per acre.

For Hula, he thinks that’s a very reasonable reality even less than 50 years from now.

“Within 50 years, yeah, I do think so. That’s almost doubling where we are. But think about where we have come. And then also think about the technology that’s coming about,” Hula says.

As advancements in seed technology continue and farmers gain deeper insight into soil health through biological tools, Hula says the future of yield remains wide open.

“But as they start figuring out how to allow the plant to be more efficient with what it can find in the soil, I’m excited about that,” he says. “And then the one key that nobody can duplicate is sunlight. As they start figuring out how to make plants more efficient with the sunlight that we have and the moisture, either lack or more, the sky’s the limit.”

Canadian Farmers Look For A Fresh Start After The Driest Year In Decades

Mon, 20 Apr 2026 18:47:21 GMT

The way Tim Webster tells it, his 2025 cropping season was nearly a disaster. Summer delivered the lowest July–August rainfall his area had seen in 50 years. That lack and abnormally high temperatures pushed corn and soybeans to their limits.

“We had just enough moisture to get to the finish line,” recalls Webster, a sixth-generation farmer based just west of Lindsay, Ontario, Canada. The end result: corn and soybean yields came in at about half of normal.

Webster and fellow farmer Steve Crothers, who farms on the north shore of Lake Ontario about 50 miles east of Toronto, recently sat down with Illinois-based Farm Journal Field Agronomist Ken Ferrie to talk about how they’re adjusting cropping plans for 2026 after last year’s drought.

Drought Reshapes Farmer Expectations

For Webster, last season was a stark reminder of how quickly yield potential can evaporate. Ultimately, Webster’s bottom line took a hit.

“We’re hoping that doesn’t repeat again,” he told Ferrie.

Crothers’ experience, though slightly better, was still defined by drought. Growing corn, soybeans, wheat and edible beans along Lake Ontario, he says it was the driest of his 40-plus years in farming.

“We had a couple half-inch rains, so we kind of ended up with three-quarters of our long-term average yield. So, we fared a little bit better,” Crothers says.

Still, the season left him and Webster concerned about their cropping plans and finances for this year.

Crop Insurance As A Lifeline

Ferrie drew a comparison between Canadian and American safety nets as he listened to Crothers and Webster describe their experiences. In the U.S., Ferrie notes farmers often lean on multiple levels of crop insurance to blunt losses in a bad production year. He asked whether similar options exist for Canadian farmers.

Webster replied that growers there do have a provincial crop insurance program, but participation and coverage levels vary.
“I think we all felt after last year, maybe we should have been insured a little higher. But we were very happy to have what we had to help pay the bills, that’s for sure,” Webster notes.

Crothers says specialty crops, including edible white beans and adzuki beans, come under similar insurance frameworks as corn and soybeans, though they have higher premiums because of their higher value.

Most of the white beans grown in his part of Ontario head to the United Kingdom, while the adzuki beans (also called mung beans) are shipped to Japan, Crothers notes. Those export markets add another layer of risk to already weather-sensitive crops, making insurance an important backstop when weather or markets turn against them.

Fertilizer Sticker Shock Hits Canadian Growers

If drought defined 2025, fertilizer prices loom large over this season for Canadian farmers, much like they do for U.S. farmers.

“For 2026 our biggest thing is hope — hope for typical average rainfalls after last year’s drought,” Crothers says. “And then, of course, the economic challenges with the fertilizer situation are obviously troubling to everybody.”

He tells Ferrie most fertilizer in his part of Ontario is not prepaid “The fellows using 28% are usually prepaid, because it’s been hard to get the last few years. But generally, not near as much fertilizer is prepaid as what, in a perfect world, would have been.” Crothers reports.

That leaves many Canadian farmers more exposed to potential sticker shock as they head into spring planting.

Webster says he pre-bought some of his nitrogen (N) in February and is now leaning hard into a strategy of splitting applications and dialing back on more expensive, slow-release N options where he can.

This year, for his wheat topdress program, fertility costs didn’t pencil out, forcing a change in his plans.

“It’s $32 more [per acre] to go with the time-release product versus straight urea,” Webster notes. “So, I think on our wheat this year we’re going to do a lot of split applications.”

With diesel, fertilizer and other costs trending higher, he says, “anything you can do to save small increments adds up … for the whole operation.”

Cropping Plans: Adjust Or Stay The Course?

Both farmers describe their region as an area where crop rotations remain fairly consistent: corn, soybeans and wheat typically share the mix. Asked whether high input prices and drought fears would drive large acreage shifts this season, Webster says his own operation plans to stay the course with its rotation, helped by a marketing strategy that spreads grain sales out over time to manage risk and meet mortgage payments.

Still, he’s aware some of his neighbors are recalibrating their cropping plans.

“I know some guys are going to go less corn, more beans — just less dollars to put it in,” Webster notes. “Maybe the profits aren’t as high, but there’s less risk involved.”

Ferrie notes that, similar to Ontario, many U.S. growers also appear to be largely holding to their established crop plans, as their major fertilizer and seed commitments were already made before input costs soared.

In a region still feeling the effects of the driest season in decades, both Webster and Crothers are essentially betting on a return to something closer to normal this season — average rains, manageable input costs and no repeat of last year’s extremes.

“If we get good yields, then we can deal with those [costs],” Crothers says. “But another weather year like last year would definitely be a struggle for a lot of people.”

Crothers and Webster spoke with Ferrie during a meeting hosted by the Durham Soil and Crop Association, a grassroots group that works under Ontario’s agricultural umbrella to bring new ideas, funding opportunities and conservation programs to farmers in the region.

The 20-Bushel Wake-Up Call One Farmer Is Using To Boost Soybean Yields

Mon, 20 Apr 2026 16:42:15 GMT

For years, Stephen Butz watched his corn yields climb while his soybeans stalled. The numbers didn’t lie: corn was steadily improving, while soybeans were “average at best,” he recalls, running hot and cold from year to year with no clear pattern.

“Our soybeans were just plateauing,” says Butz, who farms near Kankakee, Ill.

The turning point for Butz came several years ago on a 120-acre field split between two soybean varieties — 80 acres on the north side and 40 acres on the south. Everything matched: planting date, field conditions, management. The only difference was the variety planted.

At harvest, the 40-acre section of the field was 18 to 19 bushels per acre better.

A talk with Butz’s seedsman revealed the answer: the higher-yielding soybeans carried the Peking source of resistance to soybean cyst nematode (SCN). That single difference explained nearly 20-bushels-per-acre the farm had been losing to SCN for years.

“Honestly, it was just one of those deals where our seed guy had said, ‘Hey, this is a good number.’ So we’d planted the variety kind of naively,” Butz says. “But lo and behold, it was a huge benefit for us and showed us a problem we had on this farm and other farms, too.”

With the initial finding of SCN, Butz started soil testing to identify how significant the problem was across his farm. Surprisingly, soil tests revealed SCN populations ranging from the low hundreds to as high as 5,000 per sample.

“We’ve got a good amount of farms in that 3,000 to 5,000 count, which is an extremely high amount that I need to address,” says Butz, who samples fields ahead of planting.

Spring 2026: Going 100% Peking

After splitting acres for several years between non-GMO and Enlist soybeans, Butz made a decisive shift to the latter for 2026 as the non-GMO soybeans do not carry resistance to SCN.

“This spring, we are going with 100% Peking,” he says

For Butz, the move is less about chasing bonus bushels of soybeans and more about stopping the hidden losses SCN has been causing. He’s certain he’s left a lot of yield potential on the table in previous seasons.

“We’re not so much adding bushels (with the Peking) as we expect to relieve the stress that’s been taking bushels away,” he says.

Going all-Peking this season is only part of his management plan. The other piece is rotating more between corn and soybeans and, over time, between different SCN technologies, including Peking and PI 88788.

Butz’s cropping pattern follows a rough structure of thirds in any given year: about a third of his total acres in corn or soybeans and another third in continuous corn. That same structure drives his soil sampling schedule and will, in the future, he says, guide how he rotates SCN resistance traits across the landscape.

He also hopes to bring new technology into the mix, including the new SCN solution on the way from BASF Agricultural Solutions, called Nemasphere. It is the first-ever biotech trait designed specifically to address SCN.

Unlike traditional native resistance found in PI 88788 and Peking, Nemasphere is based on a transgenic trait — a Cry14 protein engineered directly into the soybean — explains Hugo Borsari, BASF vice president of business management for seeds in North America.

Beyond Yield: Logistics And Longevity

For Butz, the case for more soybeans, and especially better-protected soybeans, isn’t just agronomic. It’s logistical and financial.
Soybeans help spread out workload during planting and harvest, he explains, easing the strain of managing continuous corn acres. They also inject rotation into fields that might otherwise lean too heavily to continuous corn.

“Years of continuous corn in some spots is fine, but rotation is obviously better,” he said during a recent panel discussion hosted by BASF.

Like he found out by accident, Butz says he believes many other growers might be losing significant yield to SCN without realizing it.

“You might live in an area that you raise 75-bushel beans all the time, or 80-bushel beans, and that’s amazing. But what if the potential is 90 or 100 bushels?“ Butz asks. “There’s plenty of people out there that might be losing 10, 15 bushels off the top, and that adds up fast. You’re freaking losing $100 an acre pretty quick that would help a lot with your bottom line.”

Cut Through The Biological Noise To Find Real ROI

Wed, 15 Apr 2026 21:03:28 GMT

Biologicals are booming across the agricultural landscape, propelled by a surge of new products and high-octane promises. Yet, when the invoice arrives, farmers are often left with this nagging question: Did I actually need that?

University of Illinois field researcher and assistant professor Connor Sible is on a mission to provide clarity. Drawing on a decade-plus of in-field study in corn and soybean systems, Sible offers a farmer-first filter to cut through the marketing noise. His research is helping growers determine where these tools offer a reliable return on investment — and where they fall flat.

“Start with your agronomy, then decide if a biological adds value on top,” he advises. “They’re not a shortcut around good fundamentals.”

One of the key reasons why farmers struggle to cut through the noise and identify which biological products will work for them results from the shear number of biological products in the marketplace. Another challenge is what this class of products is called. Academia and regulators use the term biostimulants. Ag media, companies and most farmers increasingly use the broader term biologicals.

The 2025 crop biostimulant list was capped at 450 companies. Sible notes that most companies offer multiple products, so if the chart were redrawn by product labels instead of company logos, it would “get out of control pretty quickly.” In his own review of just row-crop (corn, wheat, soy) products, he examined 155 products and found 139 unique microbial species used as active ingredients.

(Connor Sible Presentation)

The Baseline: Deliver on Fundamentals

For all the excitement surrounding biologicals, Sible encourages farmers to focus on unglamorous agronomic foundations first. He describes biologicals as next-step inputs; they can sharpen a high-performing cropping system, but they will not rescue one built on outdated practices.

“I do not know of a biostimulant or biological today that will fix your pH,” Sible says. “If you’ve got a soil pH issue, fix that first. Same with drainage, and same with using the same hybrid you’ve used for six years just because it’s still available.”

The Logistics: Is it Dead or Alive?

Once the fundamentals are solid, Sible says a practical next step is to consider whether a product is living or non-living.

Beneficial microbes — such as nitrogen-fixers, phosphorus-solubilizers, residue degraders, and many seed-applied inoculants — are alive. Many biostimulants — including humic and fulvic acids, certain enzymes, and kelp- or marine-based formulations — are not.

That distinction isn’t just academic; it determines whether a product has any chance of working by the time it reaches your field.

“If you’re buying something living, you’re buying a responsibility,” Sible says. “You have to keep it alive from delivery to application.”

He urges farmers to evaluate their shop conditions: Can you provide temperature stability? Is the product sitting against an uninsulated exterior wall? If the logistics of babysitting a living organism do not fit your management style, Sible suggests using only non-living biostimulants.

Nutrient Efficiency: Boosting Nitrogen

Few biological categories have generated as much buzz as nitrogen fixers. Sible’s work suggests they can play a role — but not the one many farmers might first imagine.

For a typical corn crop, about half the nitrogen comes from applied fertilizer and about half from soil organic matter and mineralization.

Biological N fixers are best thought of as a third source of nitrogen, he says, helping to cover shortfalls when fertilizer is lost or tied up, or soil mineralization doesn’t keep pace with crop demand.

From his data on a 230-bushel corn crop, the key number is 7 pounds of nitrogen per acre per day. That’s how much the plant must take up every day for about three weeks at peak demand. At 300 bushels, that jumps to around 9 pounds per acre per day. One of the questions farmers need to ask their retailer on a nitrogen-fixing biological they’re considering is, how much will it help provide during the key periods of demand?

Corn requires significant amounts of nitrogen during key growth stages to deliver a 230-bushel corn crop. The demand makes it hugely challenging for a biological to deliver sufficient N as a standalone product.

(Connor Sible)

Sible makes two critical points:

Don’t cut N and expect a biological to fully replace it.
When growers drop early-season nitrogen in hopes that microbes will fill the gap, his team often sees corn respond by reducing kernel set. The yield ceiling falls before the biological has time to colonize and contribute.
Placement and mode of action matter.
Products marketed as N fixers don’t all work the same way. Some colonize roots externally, some live inside the plant as endophytes, and some may enhance N assimilation rather than truly fixing atmospheric N. That affects:
- Whether they’re best applied in-furrow, on-seed or foliar.
- What they can be tank-mixed with.
- When they’ll begin supplying nitrogen.

Farmers trialing N-fixing products this season should treat them as insurance or a supplement and not a license to slash N rates across the board, Sible advises.

Phosphorus-Solubilizing Microbes

Soils often hold a high volume of total phosphorus, but much of it is locked in forms plants cannot access. Certain microbes can free up this nutrient by secreting weak organic acids that chelate soil cations away from phosphate.

In field trials, the most consistent benefits occurred when microbes were supplied in-furrow or very near the roots and applied alongside phosphorus fertilizer. Using “difference methods” to track uptake, Sible reports that baseline efficiencies often sat between 4% and 7%. With a P-solubilizing product, that jumped to the 7% to 11% range in some environments.

“It’s still not great, but it nearly doubled our efficiency in some environments,” he says. However, he cautions that cutting fertilizer back significantly and expecting microbes to “mine” the difference is not a reliable strategy.

The Carbon Battle: Residue Management

Residue degradation is where Sible sees some of the strongest opportunities for biologicals, especially in high-yield or no-till systems.

Every 10 bushels of corn adds about 440 pounds of residue; over a decade, a yield gain of 25 bushels can mean an extra half-ton of residue per acre.

The challenge is the high carbon-to-sulfur ratio in corn stalks, which ties up nutrients. Sible’s research has found that biological degraders are inconsistent on their own but show significant synergy when paired with nitrogen and sulfur.

“If you’re going to use these, understand they’re fighting an uphill battle against carbon,” Sible says.

He also stresses application timing: “Spray on cloudy days or in the evening to take advantage of overnight dew. You have to set the product up to succeed.”

Carbon and Humic Products

When evaluating humic acids and molasses-type products (sugar), Sible notes a clear divide between crops. In soybeans, results have been largely inconsistent. In corn, however, in-furrow carbon and humic products produced small but consistent yield gains that held up under economic analysis.

Sible attributes this to crop physiology. Corn makes major yield decisions twice: during early vegetative stages (kernel potential) and at pollination (kernel retention). Supporting the plant during these specific windows has offered a measurable response.

Soybeans, by contrast, adjust yield daily from flowering through seed fill, making them a much harder target for a single application of a biostimulant.

Stress-Mitigating Products

Sible sees value in some stress-mitigating products — often kelp or marine extracts — that claim to help crops tolerate drought, heat or other abiotic stress. He notes these materials are often rich in metabolites that help plants survive extreme fluctuations in temperature, moisture and salinity.

When applied to crop leaves, these materials can trigger stress-defense pathways.But they only work if they’re applied before the stress hits.

“You have to be proactive, not reactive,” Sible says. “If the corn is already curled or the soybean leaves are flipped over, it’s too late for these products to do much.”

He tells farmers to watch their 7- to 10-day forecasts and time applications ahead of expected heat waves or dry spells, adding that these products are ineffective as rescue treatments.

From Products to Purpose

Across all categories of biological products, Sible’s advice remains the same: define your “why.” If a product doesn’t clearly fit a specific goal — such as improving N efficiency at peak uptake or accelerating residue breakdown — it may not be worth the investment.

“There are some really exciting tools out there,” Sible says. “But the value comes when you use them precisely, not when you expect them to fix everything.”

As farmers evaluate biological products, Sible notes there are about 10 frequently used types of “active ingredients” that are better-understood, likely credible and worth evaluating. They include:

Bacillus amyloliquefaciens
Bacillus subtilis
Bradyrhizobium spp. (classic soybean inoculant – “the original biological”)
Azospirillum spp.
Trichoderma spp.
Azotobacter spp.
Several other Bacillus and related species are in the top-10 list, as well.

Sible’s framing of these for farmers’ consideration:
If a new product contains one or more of these top 10 species, it “fits the larger narrative of this market.”
If it has something totally different, it might be:
— a random/unproven one-off, or
— truly novel and promising – but in that case he suggests being more cautious and asking more questions.

Treat Soil Moisture Like A Checkbook To Sharpen Irrigation Decisions

Tue, 14 Apr 2026 21:06:30 GMT

As irrigation costs climb and weather grows more erratic, farmers are under pressure to make every inch of water count. One of the simplest, most practical tools they can use this season won’t require new hardware on the pivot — just a different way of thinking about soil moisture.

North Dakota State University associate professor and irrigation engineer Dean Steele encourages farmers to manage soil water like their checkbook: track deposits and withdrawals, and don’t let the account get overdrawn. That mindset, he says, is the foundation of better irrigation timing and improved efficiency.

“The soil is our bank account. We’ve got withdrawals and deposits,” he notes. “Your deposits are the rain and irrigation. Your withdrawals are the crop water use and things like the deep percolation and maybe some runoff.”

The soil profile starts each growing season with a certain balance of water. Every day, evapotranspiration (ET) — the combined effect of evaporation from the soil and transpiration from the crop — pulls moisture out. Rain and irrigation add it back in.

Just as with a financial account, it’s not enough to know how much “money” moves in and out over a year. What also matters is when it moves — especially during critical periods like tasseling or grain fill, Steele says.

Why Seasonal Totals Can Mislead

Steele uses a favorite classroom trick question to show why irrigation timing is so important.

He asks students: If a crop needs 18 inches of ET over a season and the farm receives 12 inches of rain, how much irrigation is required?

The obvious answer is six inches. But that is incorrect.

“If all the rain of that 12 inches comes on May 1, and you get nothing the rest of the season, then you still need 18 inches,” Steele explains.

In that scenario, early-season rain may fill the soil profile, but if it’s not replenished as the crop draws water in July and August, the soil account will be overdrawn exactly when the plant is most sensitive to stress.

The lesson, Steele says, is that seasonal totals hide risk. Farmers need to track the running balance in the soil, not just the sum of rainfall and irrigation on a yearly chart.

Build A Simple Water-Balance Ledger

Steele says growers can implement a practical water-balance approach with tools many already have: a rain gauge, basic ET information and records of irrigation events, often available in their spreadsheet.

A basic checkbook-style water balance would include these four elements:

1. Starting balance: Estimate available water in the rooting zone at planting (for example, after pre-watering or spring recharge).

2. Daily withdrawals: Use ET estimates (from local weather networks, Extension tools or ET calculators) to subtract crop water use.

3. Daily deposits:
- Add effective rainfall (total rain minus runoff or obvious losses).
- Add irrigation applied (inches per pass or per revolution).

4. Running balance: Track how much water remains in the effective root zone relative to field capacity and a chosen depletion limit.

Steele compares ET and side losses to an unavoidable set of expenses — “groceries… housing and taxes” — that must be paid out of the account every day. If those outflows consistently exceed deposits, the crop will eventually experience stress long before the calendar suggests it should.

Adapting The Method To Different Climates

The same accounting framework applies whether you farm in the upper Midwest or the High Plains, but the numbers in the ledger will look very different.

In North Dakota, Steele notes, seasonal ET is relatively modest and summer rainfall sometimes helps “catch up,” meaning there can be more opportunities to pause or reduce irrigation when rainstorms arrive.

In the central and southern High Plains the withdrawals are much larger, according to Brian Arnall, a precision nutrient management Extension specialist at Oklahoma State University.

“Our max ETs can easily hit three‑quarters of an inch a day; our normal ET is half an inch,” Arnall says.

With 100-degree days, 30% humidity and rapidly growing corn, the soil account in the High Plains empties fast. That’s why, in many of those systems, pivots rarely shut off once they’re started, notes Arnall.

“By the end of our cropping season, we’ll probably be right at neutral, if not negative, as far as total ET and application,” he says.

For growers in Arnall’s area, the checkbook model confirms that almost constant deposits are required just to keep pace — and it can help reveal when small interruptions in irrigation might tip the balance into stress.

Match Irrigation To Crop Root Depth And Soil Type

Steele emphasizes that the size of a farmer’s “bank account” also depends on crop rooting depth and soil characteristics. Deep‑rooted corn on heavier soils can draw from a larger reservoir; potatoes on sandy ground with shallow roots cannot, he notes.

“With a corn crop… two‑thirds of an inch, that’s not a lot of water,” Steele says. In potato ground, by contrast, “if you’re managing 12 inches or 18 inches of root zone depth, that’s maybe what you’ve got to work with, so you’ve got to be around the circle more frequently.”

For farmers, that means:

In deep profiles with good water-holding capacity, the starting moisture balance is higher, and the system can tolerate larger withdrawals between irrigations.
In shallow or sandy profiles, the usable balance is small, so even modest daily ET can rapidly overdraw the account unless irrigations are more frequent.

Using The Ledger To Time Irrigation

Once a farmer has a running soil water balance, the irrigation decision can become a more disciplined approach. Steele advises growers to:

1. Irrigate when the projected balance approaches a chosen depletion threshold, not just when the soil surface looks dry.

2. Adjust application depth so that deposits match likely withdrawals over the next several days, considering forecast ET and possible rainfall.

3. Plan ahead for long pivot runs or “wipers,” where the time needed to complete a pass can allow the far end of the field to spend down its account before the irrigation system returns to that point in the field.

Steele says that on complex systems like windshield‑wiper pivots, he would pay special attention to water balance at both the starting and ending points.

“If I had a windshield wiper, I’d want to keep track of the starting and ending points and see how I’m doing, to make sure… you get back to that starting point in time,” he explains.

In practice, this might mean increasing application depth on certain passes, slowing the pivot at critical growth stages or strategically skipping lower‑risk areas where the account is still healthy.

Adding Sensors And ET Tools To The Checkbook

While Steele’s checkbook analogy can be implemented with simple records, it also provides a framework for using more advanced tech tools. Soil moisture sensors can serve as “bank statements,” verifying that the modeled balance matches reality. ET models and remote sensing can sharpen estimates of daily withdrawals, especially as researchers develop radar‑ and satellite‑based crop water use tools.

“There are people using satellite imagery as part of developing an integrated irrigation management system ... they’re keeping track of weather and soils and doing some estimation of crop water needs, and trying to estimate when the crop is going to need water, and then actually run the irrigation system,” Steele says.

In addition, local irrigation dealers and irrigation equipment manufacturers have apps and tools for managing water in the field, including variable rate irrigation. These tools are typically integrated into phone or desktop apps linked to the control panel of the irrigation system.

He suggests all of these technologies should feed into answering the same core questions: What is my soil water balance today, and what will it be if I do — or don’t — irrigate?

Manage Water Like Money

Behind the math and models, Steele’s message is that farmers who manage soil water like their money are better positioned to use irrigation when it delivers the highest return.

By tracking deposits and withdrawals, recognizing that “when” matters as much as “how much,” and understanding how soil and climate shape their account size, growers can head into this season with a clearer picture of where every inch of water is going — and whether it’s truly helping their crop.

Winter Wheat Conditions Plunge as Drought Grips the Southern Plains

Tue, 07 Apr 2026 21:56:52 GMT

The 2026 winter wheat crop is off to a rocky start as dry conditions and harsh weather take a toll on production across the Southern Plains. According to USDA’s first Crop Progress report of the season, just 35% of the winter wheat crop is rated in good to excellent condition. It is a sharp decline from the 48% reported at this time last year.

While a third of the crop is rated fair, the situation is particularly dire in Texas, Oklahoma, Colorado and Nebraska following a combination of challenging winter conditions and persistent dry weather. “Things are looking pretty rough, as we get into the heart of this early growing season for 2026,” says USDA Meteorologist Brad Rippey.

Texas Facing Extreme Moisture Deficits

In Texas, the situation is especially critical, with more than half of the winter wheat rated poor to very poor. Rippey says the state recently endured its fourth-driest stretch from September to February in the last 131 years.

Cody Pruser, a farmer near Winters, Texas, says the recent moisture hasn’t been enough to save much of the crop. “We got some rain recently, but it’s all too late, wheat’s burned up and it’s not going to make a whole lot, it’ll be below average in most places,” Pruser says. His area received about 1.5 inches of rain last week — the first significant moisture since December.

However, the timing was far from ideal. “We’ve missed the February to March rains. We’re getting them toward the end of March, the first of April, but it seems like it’s a little too late. We had decent moisture when we planted, but not much after that,” he explains.

Drought Conditions Broaden Across the Plains

Data from the latest U.S. Drought Monitor confirms the severity of the situation. More than 95% of the Southern Plains are experiencing some level of drought or abnormal dryness. In Texas, Oklahoma and Colorado, that figure reaches nearly 100%.

Despite the moisture deficit, Pruser remains cautiously optimistic he will harvest a better crop than last year, though he notes disease pressure is now a growing concern. Pruser says the biggest concern for his wheat this year is damage from High Plains virus on wheat. He predicts about 10% of his crop is impacted, which means quite a few of his acres will be unable to be harvested.

“It’s really the main concern we have with our wheat going on right now. [There is] no way to control it, nothing really to do about it,” he says.

Driest spots in the U.S. over the last 180 days.

Rippey’s Weather Outlook

Rippey says the subsoil moisture in Kansas means the state could see a turnaround from drought. The 1" to 2" of rain expected to hit the southern great plains and lower Midwest could make a big difference. “Maybe for some of the earlier wheat on the Southern Plains, we can still turn the corner and bring back some yield potential,” he says.

However, Rippey isn’t sure Western acres, or those in the central Great Plains will be able to come back from dry conditions. “Wheat’s already heading out in the far South. When you look at the numbers coming in out of Oklahoma and Texas, there’s only so much recovery at this point you’re going to have,” he says.

Fall NH3 Emphasis Set the Stage For Ugly Corn Syndrome

Mon, 23 Mar 2026 17:00:32 GMT

Farmers who leaned hard on anhydrous ammonia last fall could be in for an unwelcome surprise this spring. Despite having enough N on the books, many fields of corn across the Midwest are likely to struggle soon after planting—thanks not to how much nitrogen was applied, but where it is located now in soils.

Ken Ferrie says the current situation came about as a result of prices and product choices that drove many growers to change their N programs last fall.

“Due to price, some guys cut out or pulled back on their MAP and DAP and AMS,” says Ferrie, Farm Journal Field Agronomist. “Many farmers put on their N—all their N—as anhydrous ammonia last fall due to that price difference between liquid and smoke.”

Those choices made financial sense at the time, but they also resulted in more nitrogen being placed deeper in the soil as NH₃ — away from where young corn plants can access it this spring.

“If we dropped the dry last fall and put all of our N needs on as anhydrous ammonia, we have nothing to fight the carbon penalty stage,” Ferrie says. “The NH₃band is too deep. It’s below where the ‘fence post rots off.’ Corn roots will have to grow to it to pick it up.”

That creates a Catch-22 situation.

“The challenge is, roots will need to grow to find the nitrogen, but the carbon penalty will have them stalled out,” Ferrie explains.

Ferrie shares the example of one grower he works with who normally applies 220 pounds of nitrogen per acre, split between dry fertilizer and anhydrous. This year, that grower dropped the dry program and instead applied 250 pounds of nitrogen as fall anhydrous.

“His question: Will he still need to worry about the carbon penalty with the extra 30 pounds of nitrogen he has on? The answer is, yes. His corn will stall out for a period this spring,” Ferrie says.

How Big Is the Yield Risk?

In Ferrie’s field research, the yield impact from corn crops stalling out early in the season is clear.

“With corn on soybeans, it’s not uncommon to see a 15- to 20-bushel loss per acre,” he says. “With the G and L1 hybrids, it could get to be 15 to 30 bushels. And it gets a lot worse in corn-on-corn.”

Despite those potential yield losses, he says some growers still downplay the issue.

“This grower says his neighbor told him he has corn turn yellow every year, and he says it never affects yield,” Ferrie recounts. “Well, if you don’t check it, you’ll never know. Ignorance is bliss.”

If yellow corn in the spring has become part of your farm’s “normal,” Ferrie offers a pointed warning on hybrid choice. “If yellow corn in the spring is your MO—you just don’t feel right without having some yellow corn—I would not plant G or L1 hybrids—those that flex in girth and early length,” he says.

Inches That Matter: Banding and Carbon Penalty Rates

Ferrie’s field studies in central Illinois help quantify the amount of nitrogen needed near the surface to pay the carbon penalty.

“Our studies here show us that it takes about 60 pounds of N, minimum, placed where the fence post rots off, for bean stubble to pay this carbon penalty, and a minimum of 100 pounds worth when we’re in corn-on-corn,” he says.

One common approach growers use to build that total amount is with surface-applied fertilizer.

“Typically, we take what was surface applied as our fall fertilizer—let’s say 30, 40 pounds—and then add more surface-applied spring nitrogen to it to get to that minimum for our crop rotation,” Ferrie explains.

Another option is strategically banding nutrients near the row with the planter or a row freshener. “When it comes to keeping small plants happy, inches matter,” Ferrie notes.

He emphasizes how close the bands need to be.

“Staying within 2” to 3” of the row makes a big difference, so those crown roots can find this N in that band before the carbon penalty kicks in,” Ferrie says. “Banding some N with the planter or row freshener allows you to cut these minimums in half.”

By putting nitrogen where young roots can reach it early—near the surface and close to the row—growers can help corn push through the ugly phase instead of being stuck and languishing in it.

Don’t Let The Neighbor Decide When You Roll

Nitrogen isn’t the only factor that will shape how well corn roots perform this year. Ferrie warns that spring tillage timing and traffic decisions will also have lasting consequences.

“As our thoughts turn to spring tillage, getting the seedbed ready, remember, 80% of the compaction calls I will go on this next summer will be caused by the first pass in the spring,” he says. “Yes, the one you’re getting ready to make.”

He cautions against letting social pressure dictate when to roll.

“Don’t let the coffee shop or your neighbor set when you go to the field,” Ferrie says. “Make the decision based on your own field conditions.”

Are You Planting Second-Year Soybeans And Skipping Corn?

Fri, 20 Mar 2026 20:26:30 GMT

As input prices and markets fluctuate, many U.S. farmers are considering a shift from corn to soybeans this season. For some, like northwest Missouri farmer Todd Gibson, continuous soybeans aren’t just a one-year pivot—they are a long-term strategy to capture ROI on challenging soils.

Gibson, based near Norborne — a farming community that proudly bills itself as the “Soybean Capital of the World” — keeps a traditional corn-soybean rotation on his Missouri River bottom ground. But most of his fields with tougher, gumbo-type soils haven’t seen a corn planter in two decades.

“Growing corn on some of this heavy ground just doesn’t pay,” Gibson explains. “I’ve got some fields that have been in continuous soybeans for 20-plus years now.”

More Second-Year Soybeans In U.S. Farmers’ Plans

Gibson says he will grow more soybeans this season and on his better ground. “I’m going to cut my corn acres maybe in half. I’ll have more beans on the better dirt this year, mainly because of input prices,” he says.

Other U.S. farmers – many without Gibson’s experience – are looking to grow second-year soybeans. The Allendale Report released March 18 says private acreage estimates point to a shift toward more soybeans this season, notes Rich Nelson, chief analyst. He estimates U.S. corn planted area at 93.678 million acres, down about 5.1 million acres from 2025, while soybean acres are pegged at 85.659 million acres, up roughly 4.4 million acres over last year.

In southern Illinois, farmer and broker Sherman Newlin says the conversations he has with farmers these days are dominated by input costs and fertilizer availability concerns. While some tell him they’re sticking to their corn-bean rotations, others are considering a 100% shift to soybeans. Newlin is keeping his options open.

“I’m not planning on switching, but we’ll see,” he says. “We’ve still got a few weeks to go where we can swap out seed if we need to.”

Iowa Soybean Association Agronomist Lucas DeBruin says the farmers he works with in the state are sticking with their regular rotation and planting corn if that’s what the original plan was for this season.

“We use a lot of fall anhydrous here, so most guys are pretty locked into growing corn,” DeBruin says. “A lot of them also need the corn for livestock feed. Sometimes you can still squeeze a little bit more margin out of corn than the soybeans,” he adds, “and guys like growing corn more than soybeans. It’s more fun to pick corn.”

Look Before You Leap: The Ferrie Checklist

For farmers looking to change their seed order, Farm Journal Field Agronomist Ken Ferrie suggests taking a hard look at your balance sheet and your fields first. Here are some of his key recommendations:

Consider What You’ve Invested To Date: If you’ve already applied fall anhydrous or dry fertilizer for a corn crop, the “switch to beans” math doesn’t work. “You can’t afford to go to beans, because you’ve already spent the money,” Ferrie contends.

Account for the Yield Penalty: In a beans-after-beans scenario, Ferrie tells growers to expect a 5-to-7-bushel yield drag due to more stress from potential disease, insect and weed pressure. His question: “If you take 7 bushels off your bean yield, does it still cash flow against your corn APH?”

The Management “Claw Back": You can potentially mitigate some of the yield penalty in second-year soybeans by moving your planting date up from May to April, Ferrie says. Early planting helps the crop get an earlier and longer flowering period which can help recover some of the lost potential.

One morning this past week, Ferrie noted that the market was leaning back toward corn and that the see-saw between crops could continue this spring — another factor to keep in mind.

“Looking at the markets this morning, I think a lot of guys would prefer growing corn at $4.90 than beans at $11.10,” he contends.

The Continuous Soybean Playbook

For Gibson, success with continuous soybeans works based on a disciplined management system he relies on every year:

Fertility is Foundational. Even if you shift from corn to soybeans, Gibson says be aware that the beans could require more nutrients. He monitors his soil fertility closely, noting that continuous beans often require extra sulfur, phosphorus and potassium. He also keeps a close eye on micronutrients to ensure the crop won’t hit a hidden yield ceiling.

Non-Negotiable Seed Treatments: In continuous soybeans, the soil is more likely to become a reservoir for pathogens. Gibson hasn’t put a bare seed in the ground in 20 years. “Seed treatment guarantees me 100% replant,” he says. “It lets you sleep better at night knowing that if you get a heavy rain, you have that insurance to fall back on.”

Row Spacing and Canopy: Gibson plants in 15-inch rows at a rate of roughly 130,000 seeds per acre. The goals are quick emergence and a quick canopy. He believes a fast-closing row is your best defense against weeds and helps preserve soil moisture in the heavy gumbo. Seed treatment use and regular scouting help him feel confident in using narrow rows.

Keep Your Boots In The Field: In a corn-bean rotation, the “break” in the cycle helps farmers manage various diseases, insects and weeds. In continuous soybeans, you lose that advantage.

Gibson compensates by routine scouting and being prepared to address problems. “If you hear your neighbors have bug pressure, assume you will, too,” he says. “Don’t have the attitude that you can ‘get by,’ because you probably won’t.”

He has similar thoughts regarding weed pressure – “be proactive.” His program typically starts with a pre-emergence/burndown or early post application, with residual herbicides used to hold back weeds. If weeds break through, he is prepared to return with a post pass.

“We kind of wish sometimes we didn’t have to worry about weeds so much,” he says. “But if you don’t, then next thing you know, you think, ‘Oh, I wish we would have sprayed.’”

The Genetic Advantage: The final piece of the puzzle for Gibson is the advancement in soybean technology. He recalls the days when he says Williams 82 was his only real option for continuous soybeans. Today, advanced traits have made managing weeds and disease in continuous systems much more manageable, he notes.

On his continuous soybean acres, Gibson consistently sees yields average in the 50-to-60-bushel range. When he factors in the lower input costs compared to growing corn on heavy gumbo ground, he believes the decision to go with continuous soybeans is a good one. For Gibson, it’s not about following a trend— it’s about knowing what his land does best and having the management practices in place to succeed.

Soil Test Results Offer ‘News You Can Use’ Beyond pH

Tue, 17 Mar 2026 16:44:43 GMT

When farmers talk about their soil test results, the conversation often starts and ends with soil pH.

While that one number is important to determining whether lime is needed, that insight is just a fraction of what’s available in the lab report, says Lizzie French, soil biology manager with Waypoint Analytical, a national soil testing lab that partners with Nutrien Ag Solutions.

At a time when fertility is one of the most expensive lines on a crop budget, she believes farmers are overlooking an opportunity to pull more data from soil test results into their everyday decisions.

“We know folks who get their testing done on a regular basis, and the only piece of it they use is the pH,” French says. “That’s important, but don’t overlook the rest of the results.”

From Paperwork To Management Tool

French says the first shift farmers often need to make is mental – to stop seeing the soil test as paperwork and start treating it as a management tool.

She encourages farmers to sit down with their agronomist, retailer or consultant and walk through the entire soil test report. Some of the specific areas to address in the discussion:

Where are phosphorus (P) and potassium (K) consistently low or high?
How do those nutrient levels line up with yield history?
Are problem spots in a field reflected in the soil test data?

“That conversation is where you start turning the report into a map,” French says — a map that can guide where to invest fertilizer dollars as well as where management practices might need to change.

Establish The Baseline

French doesn’t downplay pH; she calls it the essential baseline. In the Midwest, deep soils and high organic matter can sometimes mask underlying issues.

“Before you try to do anything else on that field, you’ve got to fix pH,” she notes. But once that is accomplished, she urges farmers to dig into information on:

Macronutrients: Determine if you are in a “build, maintain, or drawdown” mode.
Micronutrients: Identify elements that may help explain why high-fertility fields are underperforming.
CEC and Organic Matter: These offer clues on how well a soil holds nutrients and water, and how aggressively the land can be pushed.

Understanding the Chemistry

The “how” behind the numbers matters, too. Waypoint typically uses the Mehlich-3 extraction method for Midwest samples, French says, because it is well-validated and provides a quick turnaround.

However, other tests are also relevant depending on the region. Dan Kaiser, Extension nutrient management specialist at the University of Minnesota, highlights Bray P-1 and Olsen:

Bray-P1: Best for predicting yield response to P in slightly alkaline to highly acidic soils (pH of 7.4 or less), Kaiser says.
Olsen: The “gold standard” for soils with a pH of 7.4 or greater, though it can be used down to a pH of 6.0.

“Many labs using the Bray-P1 or Olsen tests will run the Olsen test at a certain pH automatically,” Kaiser says. He recommends using labs close to your farm and familiar with your soil type to ensure you get the best management advice.

The Biological Frontier

Beyond traditional chemistry, French is seeing more farmer interest in soil biology—getting a holistic view of what is living in the soil and how it affects nutrient cycling.

Waypoint’s soil biology tests help answer questions that traditional chemistry might miss, such as:

Are poorly drained zones losing nitrogen through denitrification?
Is there enough biological activity to release nutrients tied up in organic matter?
Are beneficial mycorrhizal fungi active?

“They’re farming microbes, whether they are aware of it or not,” French says of growers. “They’ve always been there, and they’ll continue to be a part of that growing system.”

Understanding that microbial workforce in soils, she says, can make every dollar spent on fertilizer work harder.

For farmers looking to get more from soil tests, one of the keys is connecting that biology back to management practices and product use such as:

Reduced tillage – “If you till, you’re going to break up those fungal networks,” she says. Less disturbance helps keep the “house” intact.
Residue management and cover – Keeping soil covered and adding organic inputs, whether through manure, cover crops or residues, feeds both microbes and fungi.
Targeted products – In some cases, she says, certain humic acid products appear to help “facilitate the conversation” between roots and fungi, though results depend on the product and the system.

Biology tests can show whether these practices and products are making a difference over time — moving the discussion from theory to measurable change.

Putting The Data Into Action

French is quick to point out that farmers don’t need to become microbiologists to get more practical information from soil testing. But they do need to ask more of their reports — and of the people who work with them.

“A lot of it’s logistical,” she says of the questions she routinely hears from farmers. “‘Can you work within what I’m already doing? Can you make recommendations? Can you work with this program I’m using for data?’”

Underneath those logistics is a bigger opportunity: using the full soil test report to shape decisions about where to spend, where to save and how to build long-term soil health.

For farmers already spending the money to sample their fields, French’s message is straightforward: don’t let that investment end with addressing only pH. The rest of the numbers are there, she adds, waiting to be turned into “news you can use” on every acre.

Solving The Sulfur Shortage In High-Yield Soybean Systems

Mon, 16 Mar 2026 16:45:27 GMT

As more farmers push to plant soybeans early, one nutrient is emerging as a valuable difference-maker in the crop: sulfur. The macronutrient is helping deliver some of the largest yield responses Shaun Casteel says he has seen in recent field trials.

“Never would you think you’d see double-digit results, let alone 20-bushel numbers in soybean yield from one treatment,” says Casteel, Purdue University agronomist and Extension soybean specialist.

Yet that’s exactly what he has documented in some Indiana fields where supplemental sulfur was applied, especially in early planted soybean fields.

Why Sulfur Matters More Now

Sulfur is required by all crops, but Casteel says soybean needs are unique compared with grass crops like corn. In soybeans, sulfur is critical as a co-factor for nodulation, the biological process that allows soybean plants to use atmospheric nitrogen (N).

“If we don’t have good sulfur supply, we don’t have good nodulation and fixation,” Casteel explains. “If you’re sold short on nitrogen in soybeans, you’re sold short on yield in a major way.”

Historically, sulfur came “free” from the atmosphere and also from mineralization of organic matter in the soil. Cleaner air regulations have reduced atmospheric deposition, and Casteel says many farmers are starting to see sulfur shortages that weren’t obvious just as recently as a decade ago.

Historically, sulfur was readily available to soybeans via atmospheric deposition (acid rain) from industrial emissions, providing 10 to 30 lbs./acre annually. Due to the 1970 Clean Air Act reducing emissions by over 95%, this “free” source has disappeared, making sulfur supplementation essential to prevent deficiencies, especially on sandy soils, according to University Extension.

(Shaun Casteel)

The classic high-response situations for sulfur — coarse-textured, sandy soils with less than 2% organic matter — still stand out. But Casteel’s work is showing the story for sulfur doesn’t end there.

“I also have fields that are flat and black as a table, with 4% organic matter, where we’re getting sizable yield differences,” he says.

Early Planting Amplifies Sulfur Response

Casteel links some of the most dramatic sulfur responses to a broader trend across the country: earlier soybean planting.

In Indiana, planting patterns have shifted sharply in recent years. Soybeans that once went in the ground two weeks after corn are now being planted within a day or two of corn — and in many cases, are planted first.

Early planting improves yield potential by giving soybeans more time to develop nodes and reproductive branches. But it can also expose a weakness in the natural sulfur supply.

For those farmers chasing higher yielding soybeans, Shaun Casteel believes the use of supplemental sulfur deserves more consideration.

(Shaun Casteel)

Casteel points out that mineralization of sulfur from soil organic matter depends on microbial activity and warm temperatures. When soybeans are planted in late April or early May, Indiana soils – as week as soils in other states – are often too cool for the microbes to release much sulfur.

“In those cooler conditions, that mineralization really isn’t occurring,” he says.

Across multiple studies where planting date was combined with sulfur use, Casteel has seen consistently stronger responses in early-planted soybeans.

“We’ve got years that we’re averaging an 8- to 11-bushel response on prairie soil,” he says. In these trials, sulfur was (e.g., ammonium sulfate, pelletized gypsum, ammonium thiosulfate) applied pre at 20 pounds per acre during a 5-year period.

Beyond Fertility: A Surprising Disease Connection

Sulfur’s role may extend beyond delivering nutrition and helping fix nitrogen in soybeans. Casteel and his research team are seeing signs that sulfur helps reduce the severity of sudden death syndrome (SDS) in soybeans.

In a 2023 soybean trial, as Casteel began rating symptoms of SDS, he noticed a clear difference between sulfur-treated and untreated strips.

“We had good conditions for SDS development — cool, wet conditions during early vegetative growth. We had a marked, substantial reduction in SDS in those areas that had the sulfur treatment,” he recalls.

The unexpected result prompted a deeper look in 2024, when Casteel worked with Plant Pathologist Darcy Telenko on trials that combined planting dates, sulfur rates and SDS inoculation. Early data from those studies pointed in the same direction: soybeans receiving sulfur showed reduced disease expression.

“Beyond the fertility effect, beyond the fixation-boosting capacity that comes with this, there is evidence that we have some disease control or suppression,” Casteel says, cautioning that the results are still based on only a few years of data.

“If you really think about it, the first fungicides on the market 100 years ago were sulfur-based, so it’s not too surprising that we might be seeing something here,” he adds.

Big Upsides Where Sulfur Use Fills The Gap

Casteel is careful to note that the sulfur response in soybeans is often site-specific. Classic sandy soils and low-organic-matter fields are prime candidates for the nutrient. But his work suggests that even high-organic-matter fields can show strong gains when sulfur is limiting.

(Shaun Casteel)

That variability doesn’t dampen his enthusiasm. Instead, he sees sulfur as a high-upside tool for intensive soybean managers who already have the basics — variety selection, disease packages, and timely planting — under control.

“It’s fun to have treatments out there that are providing hope and promise,” Casteel says. “We’re seeing numbers with sulfur that really move the needle.”

With earlier planting becoming the norm and biological sulfur supply under pressure, Casteel expects interest in using Sulfur to keep growing. For those growers chasing 100-bushel soybeans, especially, he believes sulfur deserves more consideration as they develop fertility plans.

“If you have not explored sulfur on your soybean crops, I suggest applying strips of S fertilizer that is soluble (e.g., ammonium sulfate, pelletized gypsum, ammonium thiosulfate) between 15- to 25-pounds of S per acre to determine if you have fields or production practices that are responsive to boosting nodulation and N fixation,” he recommends. “Applications can be applied mid-March through planting with higher rates the earlier you apply the S fertilizer.”

El Niño Watch: 62% Chance of Arrival This Summer, But Drew Lerner Warns Extreme Forecasts May Be Overblown

Fri, 13 Mar 2026 19:58:22 GMT

Farmers are keeping a close eye on the Pacific as La Niña, which has dominated weather patterns across much of 2026, begins to give way to El Niño. The National Weather Service Climate Prediction Center (CPC) now reports La Niña persisted through February, with below-average sea surface temperatures across the east-central equatorial Pacific. However, rising subsurface ocean temperatures and weakening trade winds signal a likely shift to El Niño by this summer, potentially bringing dramatic changes to rainfall, planting conditions and crop development across the U.S.

CPC says that means the US. is now under an El Niño watch, forecasting a 62% chance that El Niño will emerge between June and August and continue through the end of 2026. But the event’s ultimate strength remains uncertain.

“There is only about a one-in-three chance that this could become a strong El Niño during October to December 2026,” CPC notes, underscoring the unpredictability farmers must plan around this year.

This transition from La Niña to El Niño could have major implications for the spring planting season in the Midwest, the central Plains, and the Southeast, where early dryness or shifting rainfall patterns may affect field work, soil moisture and crop progress.

While some meteorologists are saying there are signs this could be an extremely strong El Niño event , Drew Lerner, president of World Weather, cautions that strong of a declaration just yet.

A #LaNina advisory remains in effect. An #ElNino Watch has been issued. (2/2) https://t.co/5zlzaZ0D9Z pic.twitter.com/WpmK4dNKfn
— NWS Climate Prediction Center (@NWSCPC) March 12, 2026

Subsurface Ocean Warming Signals Early El Niño Development and Global Weather Shifts

What we do now is La Niña is making a quick exit.

Lerner says the current ocean subsurface warming is the early trigger for El Niño, which has far-reaching effects on weather patterns worldwide.

“The ocean subsurface water temperatures are anomalously warm, and we do see a strong upwelling current taking place as we move forward through the next several weeks,” Lerner says. “That will bring that warmer-than-normal water from below the surface up to the top. Once you bring it to the surface, you start shifting high and low pressure systems around the world. That’s when you’ll see El Niño beginning to influence everybody’s weather.”

Lerner notes farmers may not see immediate effects, but the pattern will begin influencing U.S. weather in a few weeks and become more pronounced by mid-summer.

“This is probably six to eight weeks before we really start to see any influence, and it will become more significant as we go through the Northern Hemisphere summer months,” he says. “We’ll likely see this El Niño become a little better defined by July and August.”

Understanding this early subsurface warming is critical for farmers to anticipate planting conditions, irrigation needs and crop development challenges.

Timing of El Niño Formation Remains Uncertain Despite Increasing Odds

While CPC forecasts a 62% chance of El Niño forming by late summer, Lerner warns several factors could shift or delay the event, making early-season planning more complex.

“There are a number of factors that could change that forecast quite a bit,” he says. “The Climate Prediction Center modified its official forecast from the raw model data. If you go to their website, you’ll see the actual forecast from their models suggests El Niño could be here in May, maybe even late April. The Australian Bureau of Meteorology also suggests it could begin in May or June. If that happens, weather around the world could start to change fairly quickly.”

Lerner stresses long-range forecast models are more reliable over three months and cautions farmers against assuming early signals guarantee timing or intensity.

“One factor is the strong easterly winds blowing across the equatorial Pacific,” he says. “If those winds lighten, it could delay the onset of El Niño. I have a lot of confidence we will move into an El Niño during the summer months, but the intensity and exact timing are still uncertain. My biggest question is how intense it will be, and at the moment, I want to play that down compared to what some forecast models have been suggesting.”

Farmers should track the weakening of trade winds and ocean temperature patterns closely, as these will influence planting schedules and fieldwork conditions in the coming months.

How Strong Could This El Niño Be?

Farmers are concerned about the potential strength of this El Niño, given its impact on rainfall, drought risk and crop yields.

“In 1998, we had a really strong El Niño that was disastrous, but it wasn’t predicted to be nearly as strong early on as it ended up being,” Lerner says. “This year is unprecedented in terms of early signals. It may also test our improved models, which attempt to forecast more than three months out. I think these models may be overreaching a little, and we could see the El Niño develop more slowly than some models suggest.”

Lerner predicts a moderately strong El Niño is possible, with peak impacts more likely in the latter part of the third quarter or into the fourth quarter of 2026.

“We might get to a very strong event, but not nearly as quickly as what some of the model data suggests today,” he says. “A moderately strong El Niño is a possibility, more likely later in the year.”

Farmers should be cautious about making early assumptions regarding extreme drought or flood events and plan for gradual changes in conditions.

Potential Impacts on U.S. Growing Season: Drier Springs, Variable Summer Rainfall

For U.S. farmers, the timing and intensity of this El Niño could bring mixed outcomes for planting and crop development. Lerner says a rapid transition from La Niña to El Niño can produce a drier bias in key agricultural regions.

“Our studies show that when we move quickly from a La Niña in January to an El Niño by June, the Midwest tends to have a drier bias in the spring,” he says. “This is particularly true in hard red winter wheat country and the central and southeastern Plains. That’s a concern because we already have dryness in some areas. A quickly developing El Niño could mean a fairly dry spring. That will help with field progress moving quickly, but crops may be limping along for a while.”

While spring dryness could help farmers get into the fields earlier, it may also stress emerging crops if rainfall does not arrive in time.

Lerner adds summer rainfall will likely vary by region.

“In the summer, situations like this often show improvement in rainfall in the Midwest and Northern Plains,” he says. “But the Delta, Mid-South, and southeastern U.S. have a tendency toward a drier bias with quickly developing El Niños. We already have some moisture deficits in the Delta, Tennessee basin and southeastern states. If rain intensities remain low, dryness could worsen as we move into late summer.”

Farmers in these regions may need to plan irrigation strategies and monitor soil moisture closely to offset potential dry spells.

Planning Ahead for Crop Management: Field Decisions, Irrigation and Risk Strategy

Lerner advises farmers to monitor early signals from the Pacific closely and to prepare for variability in precipitation and temperatures throughout the season.

“A quick movement from La Niña to El Niño could cause some spring problems in the Midwest, but much better conditions in the summer,” he says. “Meanwhile, the Delta and Southeast would probably see progressively more significant dryness by late summer. Farmers need to be aware and prepare accordingly.”

The key, he says, is understanding both the speed of El Niño development and its intensity to make informed decisions for planting, irrigation and crop management strategies.

“Pay attention and prepare for a spring with potential dryness in some areas and moderate rainfall improvement in others as the season progresses,” Lerner says. “This could influence how you handle fieldwork, fertilizer application and even crop marketing as the season develops.”

When Weird Corn Ears Wreck the Bottom Line

Mon, 23 Feb 2026 19:58:07 GMT

Abnormal corn ears may look like a cosmetic problem, but depending on the severity, they can deliver a significant hit to yield, reports Osler Ortez, Ohio State University corn specialist.

“If a field is managed for 200-bushel corn but only delivers 100 bushels because abnormal ears dominate, then every pound of nitrogen, every inch of irrigation and every pass you make across that field becomes much harder to justify,” he says.

Yield losses from abnormal corn ears can range from 35% to 91% in affected plants, with typical field-wide impacts often trailing lower, Ortez reports.

For reference, an “average” corn ear generally produces 16 kernel rows with about 800 kernels per ear, according to the Iowa State Extension.

Irregularities such as zipper ears (shown below), earless plants or multiple ears, reduce grain yield through poor kernel set, abortion or reduced kernel weight.

A common abnormality called zipper ear is caused by kernel abortion or failed pollination. The issue is often triggered by severe environmental stress during early grain fill or pollination from factors including drought, high heat or nutrient deficiency.

(R. L. Nielsen, professor emeritus and Purdue University Corn Specialist, retired)

Ortez emphasizes no single factor explains abnormal ear development. It’s nearly always the result of an interaction between three factors that corn researchers refer to as GEM:
G — Genetics (hybrid)

E — Environment (weather, stress)

M — Management (practices)

He adds that understanding when the stress is happening, the timing of it, is also important. For instance, early-season stress can limit ear initiation and potential ear number, while midseason issues impact pollination and kernel set. Late-season stress reduces kernel fill and overall weight.

Strategic Management Levers

While the weather can’t be controlled, Ortez says understanding the GEM interaction gives corn growers more leverage than they realize.

He lists three management decisions that can help growers mitigate the risk of abnormal ear development:

1. Evaluate the genetics: Treating hybrid selection as a defensive tool against ear problems — right alongside disease tolerance and standability — is one of the clearest ways to lower risk.

2. Pick a recommended seeding rate: In Nebraska field trials, Ortez observed abnormal ears increased at both ends of the seeding rate spectrum.

“Chasing a few extra bushels with aggressive populations, especially on drought-prone or otherwise stressed acres, often backfired when stress hit at the wrong time,” he notes. Conversely, pulling populations too low also created conditions where ear development went off track.

3. Consider the planting date: Researchers found planting hybrids outside the optimal window — either very early into cold, wet conditions or very late into heat and moisture stress — made it more likely sensitive growth stages would line up with damaging stress. Matching planting date to local recommendations and the strengths of a given hybrid proved to be an important way to reduce those risky overlaps.

Ultimately, by tuning into GEM, farmers can better safeguard their investments. As Ortez points out, the more sides of that triangle a farmer can stabilize or improve, the less likely a season’s worth of hard work and inputs will be undone by a field of problem ears.

Hear Ortez share more of his research on abnormal ear development in a recent podcast sponsored by the Crop Protection Network.

Mycotoxin Risk Holds Steady in 2025

Mon, 23 Feb 2026 19:49:10 GMT

According to the dsm-firmenich World Mycotoxin Survey , which assessed the global mycotoxin threat, 86% of North American samples tested above the recommended threshold for at least one mycotoxin. While mycotoxin levels haven’t necessarily escalated from 2024 to 2025, there was a shift in the distribution, which has some implications for cattle and swine operations.

“The 2025 results show a continued mycotoxin challenge, with contamination rates rising for both aflatoxins and zearalenone and average levels increasing across all major mycotoxins,” said Ursula Hofstetter, head of mycotoxin risk management at dsm-firmenich, in a press release.

The Major Players

Mycotoxins are toxic metabolites produced by fungi, most commonly Fusarium, Aspergillus and Claviceps species. They develop in the field and can persist through harvest and storage. Weather stress, hybrid selection and storage management all influence which toxins dominate in a given year.

The primary mycotoxins shaping North American livestock risk in 2025 were:

Deoxynivalenol (DON)
A Type B trichothecene produced by Fusarium species. Commonly found in corn and wheat. Often referred to as ‘vomitoxin’.
Zearalenone (ZEN)
Also a Fusarium toxin. Structurally estrogenic and frequently present alongside DON in corn and small grains.
Fumonisins (FUM)
Produced by Fusarium verticillioides and related species. Predominantly found in corn.
Aflatoxins (AFLA)
Produced by Aspergillus species. More common in drought- or heat-stressed corn.
Ergot alkaloids (ERGOT)
Produced by Claviceps species. Typically associated with small grains.

These toxins rarely occur in isolation. Co-contamination often shapes the reality producers see on the farm.

What Changed from 2024 to 2025

The 2025 North American mycotoxin prevalence in raw materials compared to 2024 shows the following shifts:

DON: 74% → 76%
ZEN: 73% → 78%
FUM: 46% → 55%
AFLA: 15% → 17%
ERGOT: 44% → 9%

Trichothecenes remain deeply entrenched, with DON prevalence increasing slightly. Most of this increase is a result of an increase in wheat (73% → 93%). Meanwhile, fumonisins rose meaningfully and ergots dropped sharply.

Cattle: Rumen Function, Immune Resilience and Production Losses

Cattle historically are considered somewhat more resilient to mycotoxins than monogastrics, owing to partial ruminal detoxification. However, evidence increasingly shows persistent exposure to Fusarium toxins like DON, ZEN and FUM, especially in combination, can exert significant effects on digestion, immunity and metabolic health.

When looking at global finished feed samples for ruminants:

DON was prevalent in 69% of samples and above the risk threshold in 53% of samples.
ZEN was prevalent in 73% of samples and above the risk threshold in 33% of samples.
AFLA was present in 34% of samples and above the risk threshold in 29% of samples.

Studies have demonstrated short-term exposure to Fusarium toxins, including ZEN and FUM, affects fermentation patterns and the microbial community, which in turn can reduce fiber breakdown and volatile fatty acid production — key drivers of energy supply in cattle. Even modest disruptions to the rumen microbiota can reduce feed efficiency and gain over time.

The immune system is also affected by mycotoxins. The immunosuppressive effects of common mycotoxins in ruminants have been documented , including alterations in cytokine gene expression, immunoglobulin production and macrophage function.

Further, individual toxins like AFLA have well-established effects on liver function and general metabolism in cattle. Chronic AFLA exposure has been linked to reduced appetite, lower weight gains and elevated liver enzymes, indicating compromised hepatic function that can impact production and health resilience.

These findings indicate how cattle performance and disease resistance can be eroded by the mycotoxin patterns reported in the 2025 data. Persistent DON and ZEN exposure, combined with higher FUM presence, places additional load on rumen fermentation and immune competence, potentially contributing to subclinical production drift.

Swine: Immune Disruption, Gut Barrier Injury and Performance Drag

In swine, elevated prevalence of DON, ZEN and FUM can exert systemic effects on immune function, gut integrity and reproductive physiology at both clinical and subclinical levels.

When looking at global finished feed samples for swine:

DON was present in 85% of samples and above the risk threshold in 41% of samples.
ZEN was present in 79% of samples and above the risk threshold in 19% of samples.
FUM was present in 44% of samples and above the risk threshold in 8% of samples.

Research has shown DON and FUM alter the gut epithelial barrier, impair immune defenses and increase bacterial translocation from the gut, making pigs more susceptible to infections even when properly vaccinated. In the immune tissues themselves, DON exposure has been linked to changes in the gene expression of key antimicrobial and inflammatory regulators, implying a weakened ability to respond to disease challenge at the cellular level.

ZEN adds another layer of complexity. Beyond its well-known estrogenic effects (i.e., swelling of reproductive tissues and altered estrous cycles), ZEN has been shown to suppress antibody production in porcine immune cells, reducing levels of IgM, IgG and IgA. These immunoglobulins are important for protective vaccine responses. This explains why farms employing what should be effective vaccination programs still report breakthrough disease.

Collectively, these mechanisms mean widespread DON and ZEN exposure is a disease vulnerability issue. When the gut barrier is compromised and immune cell function is suppressed, pigs are less able to defend against respiratory pathogens, enteric bacteria and systemic infections alike, and their response to vaccination may be diminished.

Mycotoxin Co-Contamination Defines 2025

The defining feature of mycotoxins in 2025 is not a single toxin spike, but co-contamination. Feeds routinely contain multiple mycotoxins at once and their effects overlap, creating steady biological pressure.

The result is rarely dramatic toxicosis, but production drift is reflected in reduced gains, narrower reproductive margins, lowered health resilience and increased performance variability.

With persistent DON, rising ZEN and higher FUM prevalence in North America, ingredient-level vigilance and close monitoring of performance trends are important. The mycotoxin burden did not spike, but it did rearrange.

Rethinking Nitrogen for Short-Stature Corn

Mon, 09 Feb 2026 21:43:32 GMT

Since its debut, the buzz around short-stature corn has often focused on standability—the promise of a crop that won’t fold like a lawn chair when a July windstorm sweeps across the field. But as these hybrids increasingly move from company test plots into real-world acres, farmers are discovering that standability is only one piece of the story.

In a recent deep dive into the technology, University of Minnesota Extension agronomist Jeff Coulter urged growers to look past the “miniature” aesthetic of short-stature hybrids, which are usually 7-feet tall or less (traditional hybrids are typically 9 to 12 feet).

Instead, he believes the way these new hybrids access and use nitrogen (N), other nutrients and moisture could be the key to their long-term fit on your farm.

A Different Architecture Below Ground

The most significant changes in short-stature hybrids happen where you can’t see them. Coulter says research from Purdue University found that these hybrids often feature dramatically larger and deeper root systems than traditional corn.

“[One] study found that the short-stature hybrids had 35% to 42% greater total root biomass and a deeper root system than the standard stature hybrids,” Coulter reports.

This expanded root zone acts like a web, allowing short-stature hybrids to capture more nutrients and water throughout the growing season.

Tactical Nitrogen Use

Farmers often ask Coulter if the smaller plants have lower nutrient requirements. He says the data suggests otherwise. While yields remain competitive with traditional hybrids, short-stature plants are more “tactical” with their nitrogen use.

Key research findings include:

Higher Nitrogen Harvest Index: Short-stature corn shows a 3.5% greater N harvest index, meaning more nitrogen ends up in the grain rather than in the stalks and leaves.
Late-Season Uptake: These hybrids show a 20% greater total above-ground N uptake from silking to maturity, as compared to most traditional hybrids.
Better Efficiency: Research indicates an 18.5% greater recovery efficiency of applied N fertilizer.

“If you have greater N uptake, that means potentially less residual nitrogen in the soil will be lost,” Coulter notes. This efficiency helps protect the environment by reducing nitrate leaching post-harvest.

Application Timing Is Important

Research across Illinois and Indiana suggests that short-stature hybrids respond exceptionally well to split nutrient applications.

“Compared to applying all of the N near planting, researchers found that splitting the application with half of the N at the V6 stage increased yield in 60% of the trials for the short-stature corn,” says Coulter.

Delaying that second application to V12 was less consistent, showing yield benefits in only about a quarter of the trials.

For upper Midwest corn growers, a base nutrient rate at planting followed by a substantial in-season application around V6 appears to be the strongest strategy.

Despite the smaller stature of these new hybrids, Coulter warns against cutting nutrient rates, especially N. Total nutrient demand is driven by plant population and yield, not just height. Because short-stature corn is usually planted at higher populations (40,000 to 50,000-plus plants per acre), the total N, phosphorus, and potassium needs may actually be slightly higher than in traditional systems.

Three Tips for Managing Short-Stature Corn

Maintain Your Rates: Do not reduce N applications based on plant size; short-stature hybrids’ larger root systems and higher populations require full fertility.
Prioritize V6: Use some base level of nutrients at or around planting. Aim for an in-season application around the V6 growth stage to maximize yield response.
Run Strip Trials: Use the crop’s shorter height to your advantage by running ground-based trials to compare different rates and timings on your own fields.

Coulter stresses that short-stature corn is still in the early stages of use and needs more research. That future work includes refining economic optimum nitrogen rates for short-stature hybrids at different populations and row spacings, understanding their response to starter fertilizers, and quantifying phosphorus and potassium use in the new architecture.

In the meantime, short-stature corn offers farmers a compelling combination: strong yield potential, improved standability, a more efficient root system, and the management flexibility to deliver nitrogen later and in ways that can benefit both profitability and environmental stewardship.

Coulter addressed the nutrient needs of short-stature corn, along with other agronomic insights, during the 18th Annual Nutrient Management Conference in Mankato, Minn. You can watch his presentation via YouTube here .

4 Biocontrol Strategies To Shrink Your Weed Seed Bank

Wed, 04 Feb 2026 16:27:28 GMT

Mother Nature has a way of balancing the scales, and for farmers looking to manage persistent weed pressure, biological control—or biocontrol—is one testament to that.

Unlike making a traditional herbicide pass with your sprayer, biocontrol isn’t about fast or even total eradication. Instead, it’s usually a long-term strategy designed to tip the scales in your favor, using living organisms to keep weed populations at a “manageable level,” according to William Curran, Penn State emeritus weed scientist.

While biocontrol methods are common in rangelands and perennial systems, Curran notes they can require more effort to adopt in row-crop settings where tillage and rotations can disrupt the very organisms farmers are trying to put to work.

Curran says if you’re interested in using biocontrol measures as part of a comprehensive weed-control program, there are four primary categories to consider, including:

The Classical Approach: This involves introducing a specific natural enemy into a weed-infested area. The goal is for that organism to establish a permanent home, feeding on the target weeds year after year to naturally suppress their growth and seed development. An example of this would be the use of a Canada thistle rust pathogen .
The Augmentative or Inundative Method: Bio-herbicides are one example of inundative methods. The intent is to overwhelm the weed population quickly. This practice often requires multiple applications to be effective.
Conservation Management: Sometimes, the best helpers are already in your fields. By adjusting your cropping system to be more “predator-friendly,” you can boost the populations of native organisms, like ground beetles, that naturally snack on weed seeds.
Grazing: One of the oldest tools in the shed is still one of the most effective. Utilizing cattle, sheep, or goats to graze down weed-heavy areas can significantly reduce seed banks and keep invasive species in check.

Talc And Graphite With 'Added Benefits'?

Fri, 23 Jan 2026 21:38:52 GMT

Talc and graphite are usually treated as a necessary cost in the planting process—a basic fluency agent you buy every year to keep seed flowing, prevent bridging and skips and protect singulation. But what if that same line item could work harder for you—supporting early plant health and yield instead of just smooth meter performance? That’s the door talc replacement products are starting to open, according to Beck’s Practical Farm Research (PFR) .

On a recent episode of Beck’s The Dig podcast, hosts Collin Scherer and Tyler Schindler, walked through why this seemingly small decision at the planter matters.

They contend that value‑added planter box additives are designed to do what your standard talc or graphite does for seed flow—and then layers agronomic benefits on top.

“Most growers already use a fluency agent. So what if that same line item could give you a yield bump?” Scherer said.

Over multiple years of testing, Beck’s researchers have looked at four talc/graphite replacement products that maintain seed flow but also carry biologicals and micronutrients to the furrow. The data, Scherer and Schindler say, shows positive financial returns.

“Stride Bio is now PFR-approved, with the three-year average ROI of $9.04 on corn and 13.99 on soybeans,” Scherer reported.

Other products — including GroPak AI, EnzUp SeedFlow Zn and BioWake — have also tested well.

“They’re not quite PFR-proven yet, but they’re close,” Schindler said.

A number of fluency products offer value-add potential to the planting process, according to recent research.

(Beck’s Hybrids)

The advantage goes beyond the spreadsheet. These products still do the basic job corn and soybean growers expect from a fluency agent and more.

Scherer said that the “more” often shows up as better early vigor, improved nutrient availability in cool soils, and a stronger start for both corn and soybeans.

For farmers already feeling like their planting process is overcomplicated, there’s also a practicality angle. Many of the same early-season benefits growers chase with in‑furrow systems can be captured at the seed level, Schindler noted.

“If you’re looking to simplify your planter setup, these options can deliver similar early-season benefits to intro applications without the plumbing,” he said.

The broader message from Beck’s is that in a year when cutting inputs is tempting, you can’t afford to cut the wrong ones—or leave easy ROI on the table.

“Cutting inputs shouldn’t mean cutting corners. These strategies give you a path to higher ROIs without adding costs,” Scherer said. During the podcast, He and Schindler discussed two additional ways farmers might be able to reduce input costs this season. You can hear their ideas and recommendations here .

Umbrella vs. Deep Diver: Which Corn Root Personality Fits Your Farm?

Thu, 22 Jan 2026 17:48:58 GMT

As corn yields climb across the U.S., farmers face a growing challenge: managing the massive amount of crop residue left behind. But within that challenge is an opportunity, according to University of Illinois researchers. Their work indicates that farmers who pair their tillage practices and residue management strategy with the root architecture of their specific corn hybrids can boost yield even more.

Connor Sible, research assistant professor at the university, says a good starting point in the process is recognizing what higher yields mean for residue levels in the field. Assuming an average harvest index of about 52% give or take, he notes that every bushel of corn you produce sends 44 pounds of dry matter out the back end of your combine.

You might say “no big deal” but that’s not the case. As Sible tells corn growers who question whether that’s significant: “Have your yields gone up 10 bushels? If so, now that’s 440 pounds per acre. If your yield’s 20 bushels higher, that’s almost 1,000 pounds per acre more residue on your field that you may be tilling or managing the same way you have for the last 20 years.”

Sible’s point is if your yield trend over the last decade or so has moved upward, you can assume your residue load has increased as well – and it’s probably time to rethink how you manage it.

Defining Root Architecture

The other side of the conversation about residue management is root architecture. Sible describes corn root systems as having three characteristics to consider: surface area, root angle and root mass.

“The surface area is how fibrous those roots are,” he says. “With root angle, consider are they wide angle, sometimes described as umbrella roots? Or, are they narrow-angle roots that grow deep? And then we look at the pure mass, how dense the roots are.”

What Sible and his team have determined is that wide, shallow root systems are usually most responsive to nutrients placed near the soil surface. The reason: these roots occupy the same zone where surface-applied or banded nutrients tend to accumulate in no-till or high-residue systems.

“The wider-angled roots are more responsive to split-applied nitrogen,” Sible says, as a for instance. “Those ‘umbrella roots’ are wide. They’re in the surface profile, so sidedress N goes right to where the roots are.”

In contrast, narrow, deeper root systems often perform better when nitrogen is placed deeper. In drought-prone environments or where nitrogen is placed deeper, these hybrids are genetically built to chase water and mobile nutrients moving downward, offering an advantage over the wide-angle root system.

Genetic Consistency Across Environments

One of the most striking findings from Sible’s research is how stable the root “personalities” are in the field. A PhD-level student Sible works with at the university, Sam Leskanich, determined this personality stability through field research.

Sible says Leskanich planted the same hybrids across different sites and years and then ranked the hybrids relative to each other. Whether at a southern Illinois test site with 1.8% to 2.0% organic matter and then at a northern Illinois site with organic matter above 3.5%, across dry and wet years, corn hybrids characterized as having narrow root systems stayed narrow, and wide-rooted hybrids remained wide.

The environment changes the overall size and development of the root system, but “it doesn’t change a specific hybrid’s natural rooting approach,” Sible says. That suggests root architecture is controlled by genetics.

A Call for More Data

For farmers, the practical implication is that hybrid root architecture should be matched to their production system by field. For instance, Sible and team contend that farmers might benefit from considering where water and nutrients tend to be available in their particular system, then select hybrids whose rooting patterns are well-suited to that system.

Sible adds that he believes a long-term opportunity lies in encouraging seed companies to share more information about their hybrids’ root architecture. Sible believes that adding root information to hybrid descriptions—such as surface area, angle and mass—would help farmers match hybrids not only to geography and maturity zones but also to tillage, residue level and fertility placement strategies. (Learn what Beck’s Hybrids is doing in this area here .)

Until this type of information is readily available from companies, carefully designed on-farm test comparisons across residue levels, tillage systems and fertilizer placements remain the best way for individual farmers to learn where each hybrid performs best.

As Sible puts it, “If you pick the right hybrid for your system, that can make you get a few more bushels out of what you’re already doing.”

Control the Controllables To Capture More Bushels

Fri, 16 Jan 2026 19:27:18 GMT

A solid game plan addressing key fundamentals could be the most powerful risk-management tool farmers have going into the 2026 season, according to Randy Dowdy and David Hula. Here are four they encourage farmers to review and work on this winter:

Fuel The Crop Adequately

Hula stresses that even in low-margin years, you can’t cut corners on fundamental crop needs. He emphasizes using soil tests to manage N, P and K, looking at soil pH and applying lime where needed.

“When you think about where you’re spending dollars, you can’t waiver from that,” he says. “We have to cover the basics… there’s nothing that’s sexy about farming right now, [everyone’s] just trying to survive.”

Why Your Planter Is the Lowest Hanging Fruit for Yield

Randy Dowdy says the planter represents the “lowest hanging fruit” for yield improvement on 90% of U.S. farms.

“The planter is just not performing at the levels to reach the maximum potential that most farmers need to support and service debt,” Dowdy says.

He encourages growers to spend time in the shop, ensuring that every row unit is capable of delivering “picket fence” seed placement and performance. For Dowdy, this means every seed is placed at a consistent depth and spacing, emerging within a tight window of 10 to 12 Growing Degree Units (GDUs) of one another

“Does every seed have the same standard deviation between them, the placement from one seed to the next? Are they all singulated, and are they all coming up at the same time? If that’s not happening, that’s a big deal,” Dowdy says.

Consider Seed Size Along With Good Genetics

While every farmer is tuned into genetics, Dowdy and Hula say they can benefit from taking seed size into consideration, too.

One of the questions Hula says he often gets is, “What’s the best seed size to plant?”

After years of analyzing small rounds versus large flats, his philosophy has evolved into a practical rule of thumb.

“My answer now is simple: whatever your planter plants the best, that’s the seed you want to plant,” he says.

But that only works if you’ve done your homework on the meters—cleaning them, replacing worn parts, and calibrating them with actual seed to determine the vacuum and speed settings. Taking these steps can eliminate guesswork that leads to skips and doubles.

Generally, Dowdy observes that “Deere likes rounds, Precision likes flats.”

Both Dowdy and Hula caution against the temptation of buying plateless (mixed-size) seed just because it carries a lower price tag. Their take: if you use it, run side‑by‑side strips with good, graded seed so you can see the real yield cost.

“I’d really challenge [anyone using plateless seed] to plant some graded seed next to it… just so you could know what it’s costing you. It’s costing you money,” says Hula.

Take Only Calculated Risks, ‘Miss Small’

Dowdy says this is the year to “control the controllables” and stick with practices you know consistently pay. He warns that farmers can’t afford big mistakes in this economy. While he’s not afraid of trying new practices, he is afraid of not being profitable and not being able to service debt, so due diligence and ROI have to come first.

“If we’re going to have a fail, we don’t need to fail in a big way. We need to miss small in an economy like this,” Dowdy says. “I’ll put my big toe in the water, but it won’t be my whole foot and a bunch of acres.”

A Checklist For Reference This Winter

Here are additional highlights of recommendations Dowdy and Hula listed during their most recent Breaking Barriers With R&D podcast. These are not all-inclusive, but rather a starting point for farmers preparing for spring:

1. Soil and Fertility Basics

Lime and pH: Check pH by zone or grid. Apply lime only where pH is low. Avoid wasting inputs on ground at 6.5 or higher.
Manganese Alert: Watch for potential deficiencies in high pH spots (above 6.8).
P and K Strategy: Use recent soil tests to determine if Phosphorus can be reduced. Keep Potash a priority where base saturation justifies the spend.

2. The Planter Bar and Row Units

Parallel Arms: Inspect for “oblong” wear or side play. Replace any arms that aren’t tight.
Double-Disc Openers: Use a jig to check run-out. Only use blades that meet tight tolerances for a clean V-trench.
Gauge Wheels: Lift by hand. If they feel loose or drop instantly, adjust or replace the bushings and arms.
Alignment: Use a tape measure to verify every row is exactly on target (e.g., 30 inches). Ensure the toolbar is perfectly level front-to-back at operating height.

3. Seed Trench and Closing System

Centering: Run the planter across concrete. Ensure closing wheel marks are perfectly centered over the seed path.
Row Cleaners: Adjust “trash whippers” to move residue without gouging a deep furrow that could lead to erosion or crusting.

4. Seed and Meter Calibration

Match Seed to Meter: Generally, John Deere/ExactEmerge systems prefer rounds, while Precision Planting systems prefer flats.
The Meter Test: Replace worn belts and brushes. Calibrate meters annually on a test stand using your actual seed to determine the exact vacuum and speed settings.
The “Plateless” Warning: Avoid the temptation of cheap, mixed-size seed. If you use it, run a side-by-side strip against graded seed to measure the true cost of lost bushels.

5. Management Mindset

Miss Small: This is the year for calculated risks. Put your “big toe” in the water with new tech, but don’t commit the whole farm until you see a proven ROI on your own soil.
Check Strips: Always leave a clean, untreated check strip when trying new products for evaluation.

Unmask the 'Party' in Your Corn Crop

Thu, 15 Jan 2026 20:05:44 GMT

For years, crown rot was viewed through a narrow lens—a single pathogen causing a single problem. But researchers at the University of Nebraska and Iowa State University suggest the reality is much rowdier. They report that crown rot often behaves like a disease complex rather than a solo act.

According to Alison Robertson, Iowa State University Extension field crops pathologist, the disease is frequently the result of a “party” of organisms. Robertson and Tamara Jackson-Ziems, University of Nebraska field crops pathologist, have often found a crowd of fungi – including Fusarium graminearum, the organism Phytopythium ambiguum (nicknamed “Pam”) and others – within the same rotted crown.

“One of the big unanswered questions is which ones start the infection, which ones join later, and which ones are just saprophytes feeding on dead tissue,” Robertson says.

Jackson-Ziems adds that she and Robertson are exploring the possibility that these pathogens must work together to produce the severe symptoms growers frequently see in their fields. While this complexity makes the disease harder to address, the researchers offer five practical steps you can take to prevent or minimize the impact of crown rot this season..

1. Evaluate Corn Hybrid Disease Ratings

While few if any hybrids are currently scored specifically for crown rot, field work in Nebraska shows clear differences in how various genetics handle the disease. Jackson-Ziems advises looking beyond general disease ratings.

“Talk with your seed dealer about data on hybrids specific to crown rot or early plant health,” she suggests.

Matt Essick, Pioneer agronomy innovation leader, notes that other traits are your best defense. Trait scores such as stress tolerance, stalk strength and stay-green can help combat symptoms, he explains.

2. Manage Early-Season Stress

Crown rot is heavily linked to “wet feet” and cold starts. While it is difficult to replicate the disease in a lab, Robertson notes practical experience shows that planting into cold, saturated soils—especially in fields with a history of the disease—is an invitation for trouble.

Brett Leahr, a regional agronomist with AgriGold, points out that poorly drained areas and compacted soils are particularly vulnerable.

He says a lack of strong freeze and thaw cycles to break up Midwest soils in recent years has allowed compaction layers to build, trapping moisture and stressing young roots.

Fertility also plays a defensive role. “Tissue sampling can show farmers where their nitrogen is, especially at an early stage,” Leahr reports in a press release. “Making sure nitrogen is adequate ... is key to minimizing risk.”

3. Set Realistic Expectations for Fungicides

While lab tests show that “Pam” and various Fusarium isolates are sensitive to common seed treatments and in-furrow fungicides, field results have been less consistent.

“Field trials in Iowa so far have not consistently produced crown rot to prove a clear yield or disease benefit,” Robertson notes.

Pioneer’s Essick agrees that while these products may suppress early infections, they aren’t a silver bullet. The most effective strategy remains maintaining overall plant health by reducing environmental stress and preventing insect damage to the roots.

4. Scout Early And Bring A Shovel

Farmers frequently notice crown rot at around dent stage (R5), but Robertson and Jackson-Ziems say the damage often starts earlier, between V3 and V6. They tell farmers to keep an eye out for stunted, pale or off-color plants in the midst of healthy plants.

“The first thing we might notice is that some plants may die early, and leading up to that, you might see some really odd discoloration. We call it ghosting—an off, ugly, greenish-gray color where the tops of the plant die,” Jackson-Ziems explains.

To confirm your suspicions, dig up the dead plant, wash the roots, and split the crown lengthwise. Look for brown, discolored tissue and root loss.

If you find significant “ghosting” in fields, Leahr recommends a proactive harvest strategy. “If you see a lot of ghosted plants in the field, consider making plans to harvest it early,” he says, suggesting a 5% threshold for prioritizing those fields.

5. Document And Share Your Findings

Because so much is still unknown about crown rot, on-farm data from affected fields is invaluable. Robertson and Jackson-Ziems encourage growers to keep detailed records of planting dates, soil conditions and hybrid performance.

Also, consider diagnostic testing of affected plants and sharing the results with your agronomist and university Extension specialists. What you share can contribute to a larger pool of knowledge about the disease. The faster researchers can identify which organisms are leading the “party” in your corn crop, the faster they can develop the tools needed to help you shut it down, say Robertson and Jackson-Ziems.

No-Cost And Low-Cost Ways To Grow More Profitable Soybeans

Wed, 31 Dec 2025 17:01:44 GMT

As soybean growers face razor-thin margins next year, the temptation to chase new products and practices is understandable. But decades of research show that the most reliable return on investment doesn’t come in a jug—it comes from focusing on good fundamentals.

University of Minnesota Extension agronomist Seth Naeve tells Farming The Countryside host Andrew McCrea there are a number of reliable practices that can help farmers grow more profitable soybeans with little or no added cost next season. Here are five of them:

1. Use Row Spacing To Your Advantage.

Row spacing is one of the most underrated tools farmers have available, Naeve reports. Across a wide range of environments, narrowing soybeans from 30-inch rows to 20–22 inches will deliver about a 5% yield increase.

“That’s three or four bushels, in a lot of cases,” he says. “Farmers are working really hard, buying a lot of products out there, trying to increase their yields by two or three bushels; whereas, adjusting their row spacing would get them to that basically guaranteed.”

Naeve adds that if farmers go from 30-inch rows to drilled soybeans, they could potentially pick up 10% additional yield.

“That would take you from 60 bushels to 66 bushels or from 80 bushels to 88 bushels. It’s not at all unrealistic,” he says.

Why narrow rows deliver on better yield: the canopy closes faster, there’s better light interception by the crop and more efficient use of space.

Naeve says he has preached the message that farmers can benefit from going with narrow rows for years, but the practice hasn’t gained as much traction as he believes it warrants. Equipment cost has been one deterrent, and the other is farmers just haven’t bought into the practice.

“Farmers pretty much universally believe that the row spacing they’re using is probably the best for them, and I think that makes them feel comfortable about their systems,” Naeve says. “I certainly can’t argue with them if that’s really their belief.”

Still, Naeve wants to encourage farmers who are changing planters or open to adjusting their systems to seriously consider going with narrow rows.

2. Consider Whether You Can Scale Back On Plant Population.

Research shows farmers can achieve maximum soybean yields with fewer plants per acre when they focus on achieving a uniform stand across fields.

“We can optimize yields at very low levels” Naeve says. “We have done a ton of research showing where we have yields that are maximized at below 100,000 plants per acre, as long as they’re well distributed.”

Naeve says to use precision placement practices where possible. You can adjust seeding rates upward as needed to address tough areas within fields, higher risk conditions (cold, crusting soils), or if you’re using lower-quality seed.

“My take home on this is a farmer wants to ensure they’ve got 100,000 plants on every single acre of their whole farm,” Naeve says. “But if they don’t sleep well at night because they’re concerned about their crop, adding another 5,000 or 10,000 seeds is an easy way to fix it.”

3. Plant Early—Within Reason.

Naeve says across most of the Midwest, the sweet spot for planting soybeans is from late April into early May.

“Very early May planting puts us into a situation where we can basically maximize yields across almost all the Corn Belt,” he notes.

Going earlier than late April can help yields in some years, but risk rises from poor environmental conditions (cold, wet soils). A freeze will also cancel the benefits.

For many growers, Naeve says the “real decision” is whether to plant soybeans or corn first, and more farmers are finding that putting some soybeans in the ground ahead of corn can be a winning strategy.

4. Consider Using Reduced Tillage.

In northern areas like Minnesota, full no-till soybeans often lag a few bushels behind conventional tillage due to slower warming of soils and slower emergence. But Naeve says there is a lot of middle ground for farmers to consider with their tillage practices.

For one, he says strip tillage can deliver comparable results to full tillage with less fuel and machinery costs along with providing less soil disturbance.

“Reducing the number of passes, even if not full no-till, saves money and protects soil health without a big yield hit,” he says.

5. Spend Input Dollars Where You Know They Pay.

Stay with tried-and-true products in these tight times, Naeve encourages. He says research shows that products sold mainly as yield enhancers or general “plant health” boosters rarely deliver consistent yield benefits across multiple locations and years.

What does consistently pay: making sure fertility, especially macronutrients, is not yield limiting, and investing the time to choose the best varieties for your ground and practices.

“Variety selection is one of the most profitable decisions a soybean farmer makes, yet it is also one of the hardest,” he says. “If farmers move from premium brands to more economical seed this season, they can still do well, but they must be more careful in sorting through the options because there may be more variability in performance.”

Beyond Bushels: Align High-Yield Strategies With Your Crop Budget

Mon, 29 Dec 2025 20:30:45 GMT

A practical crop budget can serve as a valuable farming playbook, offering essential direction and guidance from planting through harvest, according to farmers and business partners David Hula and Randy Dowdy.

“Return on Investment (ROI) is the primary focus for the year ahead,” says Dowdy, who farms near Valdosta, Ga. “Everybody is trying to figure out how to survive this lean time, because we don’t have $8 corn or $15 beans.”

Start The Season Strong

For Hula, the strategy for achieving both high yields and ROI begins with selecting the right hybrids and using excellent planting practices, followed by consistent nutrition.

“You want to feel optimistic that you’re going to have high yield potential starting out,” he says. “Then, you need to make sure the crop has all the groceries it needs, because if it runs out of juice at any one time, you’ve just hit the minus button.”

Power Of Finishing The Crop

Hula highlights that another critical component of maximizing ROI, even in current tight markets, is finishing the crop well.

He shares that despite having a challenging growing season this year, his dryland acres achieved their third-best farmgate average. He attributes that to ensuring the crop received the necessary resources late in the season, especially a fungicide application.

“We felt pretty confident [the crop] was going to deliver... and that was mostly because we finished it well. We were picking 66.7 to 67 pounds test weight corn at harvest,” reports Hula, who is based near Charles City, Va.

“Finishing the crop is by far where a lot of people leave a lot of yield on the table,” adds Dowdy.

Use ‘Bushels’ To Track Costs

The current market outlook for 2026 necessitates a sharp focus on expense management, Dowdy notes.

“Obviously servicing debt is still on everybody’s mind. A farmer should never cut out anything that he or she knows makes money. But the problem is sometimes they don’t always know what that is,” he says.

When planning the budget, Hula urges growers to shift their perspective away from the cost of the input and toward the bushel return needed to justify it.

He offers, as an example: “For me to do in-furrow, that requires seven bushels. If I’m not going to get a seven-bushel return per acre, I’m not going to do it.”

Hula believes the bushel ROI mindset should be applied to all inputs. By framing decisions in terms of bushels rather than dollars, he says growers can more easily see the economic impact of each investment they make.

Make Every Input Pay Its Way

Hula and Dowdy are spending significant time this winter consulting with growers on budget strategies through their business, Total Acre . In many cases, they are stressing the importance of refining in-season input applications to make them more efficient, rather than cutting them completely.

“We can keep some of the in-season applications and make them more efficient by placement,” Dowdy says. “The goal is not merely to cut costs, but to find better, more efficient ways to invest money that directly leads to a higher ROI.”

Iowa Farmer Battles Today's Pests While Eyeing Tomorrow's 'Mean Sixteen' Threats

Fri, 12 Dec 2025 18:52:50 GMT

For Worth County, Iowa, farmer Sarah Tweeten, the list of high-priority agronomic threats isn’t a political abstract — it’s a harsh reality she deals with every season.

Farming with her parents, Brian and Julie, and her uncle Roger, Tweeten has been steering the partnership toward more resilient cropping practices since joining the operation in 2021. This includes shifting from conventional tillage to strip tillage and splitting nitrogen applications.

The changes are part of a broader mindset: Protecting yields today from weeds, disease and insects while aggressively preparing for the next generation of agronomic threats. This forward-thinking approach is what led Tweeten to Washington, D.C., earlier this week as a Farm Journal Foundation farmer ambassador to help introduce a new report: “ The Mean Sixteen: Major Biosecurity Threats Facing U.S. Agriculture and How Policy Solutions Can Help. ”

Today’s Battles and Tomorrow’s Warnings
Researched and developed by Stephanie Mercier, PhD, the report takes an in-depth look at 16 significant pest issues U.S. farmers face now or could realistically in the future.

Tweeten is already battling a couple of the problems that underpin the urgency behind the research. For example, Palmer amaranth (pigweed) is gaining ground in her fields and across Iowa. The pervasive broadleaf weed can drastically reduce yields, with studies showing corn yield reductions between 11% and 91% and soybean yield reductions of 17% to 68%.

“We’ve struggled with pigweed as it continues to establish more resistance to our herbicides in our toolkit,” Tweeten says.

Two additional agronomic issues the report details include:

1. Asian Soybean Rust. First detected in the U.S. in Louisiana in 2004, this fungal disease has spread to southern states like Georgia and Mississippi. Scientists warn that warming winters could enable its migration to the Midwest, adding to existing disease pressures.

2. Corn Ear Rot. It can lead to aflatoxin production, making corn unmarketable and posing risks to humans and livestock. Aflatoxin is an issue Pickens County, Ala., farmer Annie Dee says is an ongoing problem for corn growers in her area.

“If we have aflatoxin, it can be impossible to sell the corn,” says Dee, also a Farm Journal Foundation Farmer ambassador.

A more recent threat she references is the impact of Highly Pathogenic Avian Influenza (bird flu) on local poultry farms.

Since January 2022, HPAI has been confirmed in a commercial or backyard poultry flock in all 50 states.

(USDA)

“An important market for us is poultry feed meal, so that’s a constant worry. The trickle-down effect is if we can’t move our corn then we can’t meet our financial obligations,” Dee adds.

Despite agricultural R&D offering a high ROI — $20 in benefits for every $1 spent — the Farm Journal Foundation report notes public funding for ag research has been declining over the past two decades.

“Farmers urgently need sustained support for aflatoxin research and prevention because these risks threaten our yields, our markets and the trust consumers place in American agriculture,” Dee says.

U.S. public spending on ag research and development has been falling for two decades.

(USDA-ERS)

African Swine Fever Has ‘Devastating Potential’
Looking to the future, Tweeten says she is concerned about African swine fever (ASF) and its potential to impact crop farmers as well as hog producers. The highly contagious swine disease hasn’t been detected in the U.S. mainland, but it isn’t far away. ASF has been confirmed in the Caribbean countries of Haiti and the Dominican Republic, roughly 700 miles from Miami, Fla.

“Being a farmer from Iowa, where we have probably eight times the amount of pigs as we do people, an outbreak of ASF would be just devastating to our state,” Tweeten says.

Hogs are among the biggest customers for the corn and soybeans Tweeten and her family grow. If African swine fever were to shut down hog production or exports, it wouldn’t just be a blow to livestock producers – it would hurt the entire agricultural community, she contends.

Read about 5 livestock diseases that could impact U.S. food security and economic stability.

Food Security Is National Security
When it comes to justifying funding for ag research, Tweeten knows there’s competition for every federal dollar. But she believes agriculture deserves a front-row seat — not only because of its economic weight and impact on farmers, but because of its role in national security.

“There’s that argument that food security is national security,” she says. “If there’s one thing COVID made us aware of, it’s that a disruption to our food chain can be terrifying, quite frankly.”

The pandemic made consumers and policymakers more aware of supply chain vulnerability. In 2020, the shock to the supply chain came from a human disease and logistical bottlenecks.

Next time, Tweeten says, the disruption could just as easily come from animal or plant disease — whether African swine fever in hogs, Asian soybean rust or some other pathogen in crops. She worries about scenarios where farmers could face a fast-moving disease or crop pest while critical tools are still hung up in regulatory delays.

Her message: Farmers need a full toolbox, not one that’s half-built by the time a threat arrives.

“Ag needs to be in a good position when these sorts of emerging diseases and pests come into the country,” she says, “to have the tools in our toolbox ready for farmers to pull out.”

Living Sensors Turn Soybeans into Fungal Disease Detectives

Mon, 08 Dec 2025 21:06:49 GMT

For Aidan Kleinschmit, trying to get the upper hand over white mold disease in soybeans used to involve a frustrating amount of guesswork.

White mold can lurk in soybean fields undetected for weeks, causing significant damage before any visible symptoms appear. Kleinschmit says his annual struggle with the disease turned a corner this past season when he decided to trial the use of CropVoice from InnerPlant.

“I remember they sent out an alert on a Saturday night about white mold being detected, and by Monday we had decided we were going to treat,” recounts Kleinschmit, who farms in northeast Nebraska with his dad and brother.

“That put us way ahead of the white mold, because by the time you see it some damage is done,” Kleinschmit adds. “You might get disease suppression from a fungicide at that point, but you’re going to have some yield loss.”

Early Detection: A Game-Changer For Disease Control
The proactive treatment Kleinschmit made included whole-field fungicide applications as well as some targeted spot spraying with a drone over 500-plus acres. The payoff was evident in yield results Kleinschmit saw at harvest.

“We sprayed one entire field in our bottom ground, and it made about 86 bushels per acre,” he says. “That was well over, probably 25 bushels better, than what some of the other fields in our bottom ground yielded.”

Gary Schaefer, chief commercial officer at InnerPlant, says the big takeaway with CropVoice is the tool gives farmers real-time disease detection, informing decisions on whether to spray a fungicide. This directly addresses the ambiguity that farmers like Kleinschmit have long faced with disease management decisions.

“CropVoice is designed to deliver ROI by either saving costs in years when spraying isn’t necessary, or by enabling timely, effective action during heavy disease pressure, significantly improving the efficacy and financial return of fungicide applications,” Schaefer says.

While Schaefer doesn’t say what the return-on-investment for using CropVoice is, he contends that for every dollar a farmer spends on technology or an input “they should get at least $3 back,” a number Kleinschmit affirms as being on par for his expectations.

A ‘Cell Phone Tower’ for Soybean Fields
CropVoice is the first product InnerPlant has designed for farmers. How the technology works hinges on a seed biotech trait the company has developed that turns soybeans into living sensors that detect disease at the molecular level. The soybeans emit a fluorescent optical signal within 48 hours of a fungal infection – before any visible symptoms appear.

The company is placing its soybeans in sentinel plots that act like an early alert system in a defined geography. CropVoice analyzes the data coming from the plots 24/7. If a foliar disease moves into the plots, farmers and retailers working with InnerPlant are alerted that the disease is in their area.

Schaefer says to think of the sentinel plots as working like a network of cell towers for farmers whose fields are the cell phones.
“What you’re subscribing to is the network of cell towers that gives coverage for a broad area,” he explains.

For 2026, InnerPlant is placing 100 sentinel plots in fields across Iowa, Illinois, Nebraska and South Dakota to achieve the cell tower network effect for farmers in those states. Each plot will range in size from one-eighth acre to one-fourth of an acre.

Cultural Practices Play An Important Role
The soybeans grown in the sentinel plots mimic the cultural practices representative of soybean growers in each state. The strategy ensures highly relevant data for farms that are enrolled in InnerPlant’s program, which is implemented through strategic partnerships with retailers, Schaefer reports.

Farmers enroll their soybean acres in the InnerPlant network for a fee ($6 per acre for 2026). Retailers facilitate the process, mapping fields into the company’s program for retailers’ continuous monitoring throughout the growing season.

Participating farmers get weekly scouting reports, which include a disease score indicating risk levels in their area along with a detailed map showing any disease progression in their area. In addition, the company provides real-time disease alerts that are pushed directly to farmers via text anytime CropVoice detects a disease in the sentinel plots in thearea.

“The plants will turn on to any fungal pathogen,” Schaefer reports. He says end-of-year scouting reports from 2025 in Nebraska and Illinois revealed the detection of between five and seven different fungal pathogens in the company’s plots.

Kleinschmit says the proximity of the sentinel plots to his soybean fields and the early text alerts are two of the factors that sold him on enrolling a portion of his acres in the program.

“We’re only going to spray acres that we think are going to be affected by white mold at this point. I thought the technology really gave us a good benefit there,” says Kleinschmit.

“There are so many variables and moving parts in farming, so if there’s a way to help minimize the guesswork to help us make a good decision, I’m going to look into it and try it,” he adds.

Other technologies are also being explored by researchers for early soybean disease detection, such as hyperspectral imaging for charcoal rot and the Sporecaster smartphone app from the University of Wisconsin–Madison. The latter predicts white mold risk based on weather data and field conditions.

Expanding the Network: Coverage for 2026 and Beyond
InnerPlant expects to scale up to more than 500,000 soybean acres across Iowa, Illinois, Nebraska and South Dakota in 2026 and plans to expand beyond those states over time.

To learn more about the technology, farmers can connect with participating ag retailers or reach out directly to InnerPlant.
Schaefer says the companyis hosting demos this winter, offering a firsthand look at this real-time, plant-based technology that could redefine how farmers address key diseases in the future.

He adds that InnerPlant will start field testing a corn fungal sensor in 2026, aiming to expand the plant-based disease detection technology to even more farmers and geographies in the coming years.

Avoid The Pitfall of Leasing Farmland With Low Fertility

Mon, 01 Dec 2025 22:46:05 GMT

Farmland often changes hands in the fall, and such exchanges are currently underway across the country as farmers and landlords look to finalize deals for the 2026 season. But some of the ground changing hands is in poor condition with regard to fertility, according to Ken Ferrie, Farm Journal Field Agronomist.

“I’m really shocked at how poor the stewardship is on some of these farms,” says Ferrie, who is seeing the issue in central Illinois, where he’s based. “We have seen multiple pieces of ground this fall that have been literally sucked dry of fertility and are sitting in bad shape on pH.”

While Ferrie isn’t sure how widespread the issue is, he says more farmers have reached out to him about the problem than in previous years. He attributes much of the issue to non-operating, absentee landowners who might not understand the need for good stewardship practices to keep ground productive. In other cases, he is concerned some landowners are simply interested in financial gain.

“It’s often land they inherited, [and they’re] two or three generations away from farming,” Ferrie says. “They look at it like an investment in the stock market.... In many cases, their relatives, the original landowner, would be turning over in their graves if they could see what’s happening to some of this ground.”

Conservation Practices On Rented Ground
Around 40% of all farmland in the U.S. is rented — in some U.S. counties that number is nearing 80%. According to USDA data, 283 million acres (30% of all farmland) are owned by non-operator landlords — those who own land used in agricultural production but are not actively involved in farming it.

The American Farmland Trust (AFT) reports that many non-operating landowners are unfamiliar with conservation practices or have difficulty discussing long-term goals with their renters. One survey found that 65% of non-operating landowners rely on their farm operator or someone else to make decisions on conservation practices.

“This dynamic can lead to a lack of investment in practices that improve productivity and resiliency of the land,” AFT reports. “Some of the areas with the highest rates of rental agricultural land are also those experiencing high rates of soil erosion and nutrient losses.”

Due Diligence Can Prevent A Costly Investment
Leasing land with low fertility levels can create financial hardship for unsuspecting growers. Such “hidden” costs frequently impact younger farmers who have limited resources and opportunities to rent ground.

“Many times, it’s our younger growers looking for land to expand their operation that seem to get caught up in these sucked-dry, short-term cash rent scenarios,” Ferrie says. “For short-term leases, that could be an anvil around your neck. There may not be a way to gain profitability short-term on some of these farms.”

While cash rents are softening slightly in some states for 2026, they still represent a huge investment for growers who are unlikely to see improved commodity prices to counter their investment in land and other inputs.

Table 1 provides average USDA cash rents across 4 land classes defined by soil productivity index (SPI). Average cash rents declined for the excellent, good, and average land classes while average rents slightly increased for areas classified as fair. Table 1 also provides average cash rents by land class as reported by the Illinois Society of Professional Farm Managers and Rural Appraisers (ISPFMRA). Average rents on professionally managed farmland tend to be higher than the averages reported by USDA.

(USDA and others as noted)

Ferrie’s advice for farmers looking to pick up more ground: do your homework thoroughly before signing on any dotted line. Here are three steps he recommends farmers take as they consider renting new ground for the year ahead:

1. Avoid making assumptions. “Don’t assume just because a piece of land is being managed, that stewardship is being followed,” Ferrie cautions. “Farm managers work for landlords/owners. If they want the farm taken care of so it can be passed down to future generations, they’ll make it happen. If the landlord wants the highest return without any regard to stewardship that, too, is the farm manager’s job,” he explains.

2. Ask for current soil tests and yield maps. That will provide some insights on how the ground has been treated and its general productivity.
“If the leaser is not supplying any information, talk to the neighbors, if possible. Ask whether they ever see a lime truck on the farm,” he says.

Another option is to ask the leaser if you can pull some spot soil samples to get a feel for fertility in the field.

“If the answer or situation is no, ask about a conditional lease based on soil fertility levels once you do get the field tested,” Ferrie advises.

3. Gather information about past practices on the ground. For example, Ferrie says if you no-till, you’ll want to evaluate whether there are horizontal layers present in the field.

“I’ve seen in many situations where the No. 1 hurdle is removing compaction layers left by the previous tenant,” Ferrie says. “If you rent the ground, you’ll need a plan with your agronomist on how to address that.”

Different Factors Influence Farmers Who Are Buying Land
Ferrie points out that poor soil fertility across a parcel of ground might not be as concerning for farmers who are purchasing the property.

“I’ve been told by more than one realtor and farm manager that soil fertility doesn’t matter when selling a piece of ground, and that low-fertility fields will bring the same as farms that have received good stewardship. And this is apparently true based on what I’m seeing on farms that we are testing,” he reports.

He believes the reason is those farmers often have confidence that they can bring their new ground up to speed production-wise over time. And time is on their side as most buyers make the investment planning to hold onto the ground for the long haul.

3 Corn Disease Lessons You Should Apply in 2026

Wed, 19 Nov 2025 22:37:12 GMT

As farmers continue to battle through the valley of the current farm economic cycle, they can glean valuable lessons about managing corn disease from the 2025 season. According to Farm Journal Field Agronomist Ken Ferrie, these three takeaways can apply next year:

Diseases might be severe in one area but nonexistent a few miles away.
Designating a pest boss and a pest management team pays big.
Don’t walk away from your crop.

Here You Find Disease, There You Don’t

“In 2025, in many areas of the Corn Belt, farmers experienced 10-to-50-bu. yield losses from corn disease,” Ferrie says. “The big problems were tar spot and southern rust, often in the same field. When disease was discovered in time, damage was somewhat preventable.

“Here’s what made management tricky: One field would be at threshold levels for treatment, but 5 miles away fields were disease-free. It boiled down to the disease triangle, requiring a susceptible host, a pathogen and the right environment. In some areas, where the three components never came together, growers harvested some of their highest yields ever with no fungicide.”

That hit-and-miss disease situation, in a period of tight profit margins, made scouting fields and having a pest boss making timely treatment decisions even more crucial than usual.

These photos taken through the windshield of a combine show the impact of a disease compared to two applications of a fungicide. Besides higher yield, the stay-green effect of the fungicide can also lengthen the harvest window.

“Where disease was present, many growers netted a 25-bu.-to-40-bu. yield response from a fungicide application,” Ferrie says. “Good managers who continued to scout often discovered diseases coming back about two weeks after treatment. Many of them sprayed a second time and netted another 20-bu. or 30-bu. response in addition to improved standability. That’s why I say never walk away from a growing crop.

“Conversely, many farmers who failed to identify disease in their fields and did not apply a fungicide found their yields shrank by 40 bu. per acre from their July estimates.”

Go Low for Rust and Tar Spot

One lesson from 2025 that applies to fungicide application confirmed Ferrie’s previous studies and observations.

“Last season, tar spot and southern rust started low on the plants and worked their way upward,” Ferrie says. “Fungicides had to penetrate deep into the canopy to control them.”

With aerial application, big droplets often fell beneath the aircraft and penetrated the canopy. But the smaller, lighter droplets floated to the outside of the pattern, remaining on the top leaves. Most years, that’s not a problem; but in 2025 it provided streaky results.

“With ground applicators, we did not see that streaking effect, because we got good penetration across the swath,” Ferrie says. “They put the fungicide down low, where it was needed.”

Lesson for 2026: To control tar spot and rust low in the canopy, when using aerial application, narrow your spray pattern.

“If you have both diseases in a field, make sure you use a fungicide that controls both,” Ferrie adds.

Your Pest Management Team

“Don’t have a pest management team yet? The offseason is the ideal time to assemble one. Here’s some advice to help:

A team can consist of farm employees, retail employees or scouting services. Hesitant to use someone who sells products? “Lots of great pest managers work in retail,” Ferrie says. “Their success depends on you being successful also.”
You might want to assemble several teams, for various issues such as weeds, disease and insects.
On a smaller operation, the whole team can be just one person, but make sure someone is authorized to make timely decisions.
The team must know how to collect accurate data, including good pictures for the pest boss. There’s no room for emotion in their reports.
Scouting must not stop after a treatment is applied. “If a disease resurges, as many did last year, it can shorten the grain-fill period and turn a great crop into a mediocre one,” Ferrie says.
Just like the scouts, the pest boss must base decisions on data, not emotion, coffee shop conversation or someone else’s team.
While market prices influence the economic threshold of when to treat, don’t let them create an emotional situation where the option is to treat or not to treat.
The pest boss must consider crop insurance coverage when making treatment decisions. Is the operator insured? The landowner? For how much? Do any other insurance factors apply?
