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.”

Farmers Emphasize Demand, Not Payments, Is The ‘Bridge To Better Times' For Agriculture

Wed, 22 Apr 2026 22:25:36 GMT

Two Midwest farmers are pinning their hopes for the future on stronger demand for corn and soybeans — especially the latter — as they navigate tight margins, high input costs, and an uncertain price outlook.

Northern Illinois farmer Steve Pitstick and south-central Iowa farmer Dennis Bogaards say they have exhausted most cost-cutting options for this season. They believe future profitability now rests on whether demand for both crops — particularly from domestic soybean crush and fuel markets — expands enough to support higher prices.

One silver lining currently, Pitstick says, is his relatively strong position on fertilizer heading into the 2026 planting season.

“We will do pretty much the dry spread program we always do,” he says. “We cut the rates a little bit on the phosphates just because of price. We booked our 32% in September, something we traditionally do. We have all the nitrogen bought, so I feel good about 2026 from that aspect.”

While he believes additional fertilizer is available, he notes it will likely be priced at a premium.

“I believe I can get more if I need it. I may not like the price, but I can get more,” he told AgriTalk Host Chip Flory during the weekly Farmer Forum segment.

Little To No Expansion On The Horizon

As the season begins, both farmers emphasize that the coming years will have farmers focusing on survival and strategic adjustments rather than acreage expansion.

One adjustment Bogaards is making is front-loading some of his nitrogen needs this season while leaving a portion open in case prices break.

“We booked anhydrous early on for this year, back in early fall, and got an OK price,” Bogaards says. “I have a little bit of sidedress that we do. We book about half of that, and I sit open on the rest of it. I’ll wait and see where it goes.”

Bogaards remains committed to sidedressing as long as product is available and prices do not continue ratcheting up. “If I can get it, I’ll put it on, unless it is a crazy, crazy price,” he says.

Like many U.S. growers, both Bogaards and Pitstick say there is virtually no room left to cut fertilizer use without risking yields.

“There is no place to cut back. We are being as efficient as we can be,” Pitstick says.

Bogaards agrees, noting that nitrogen is not the place to skimp. “Maybe a year or so, you can cut back on the P and K a little bit, but you do not want to get caught in three or four years of that.”

He also remains reluctant to drop fungicides. “Fungicides really pay off,” he says. “In the past, we did not use them, but the last few years they really paid, and I would hate to not spray them.”

Uncertainty About The 2027 Crop Mix

While the 2026 crop is largely “business as usual,” both farmers told Flory that 2027 brings real uncertainty—especially regarding nitrogen supplies. Pitstick is concerned about how global demand could impact costs for U.S. producers.

“I am worried about the price of the nitrogen,” he says. “It may not be an issue in the United States from a supply standpoint, but the rest of the world… could export our product because of opportunity cost, and that drives the price up. It is a total wait and see.”

Flory underscored how global trade flows directly shape what American farmers pay, noting that some fertilizer shipments originally destined for the U.S. were recently rerouted.

“Some boats are diverted from the U.S. to other countries,” Flory says. “If you want your share, you have to beat the next guy in line with the price.”

If nitrogen prices soar while corn prices stagnate, Pitstick says his rotation could shift. “That might change how we do things in 2027. We may have to go to more soybeans,” he says.

Bogaards also expects to alter his corn–soybean mix, given the potential demand from domestic crush and renewable fuels.

“In the past, we were probably 60% to 65% corn,” he says. “We have been backing off of that. I still do a little bit of corn-on-corn, but I might try to go to a 50–50 rotation.”

Flory believes this shift could help rebalance supplies and improve price prospects. “If we can pull some acres away from corn and get this thing rebalanced, maybe that is our bridge to a better time,” Flory says. “Our bridge to a better time is more demand across the board and crops competing for acres — not another payment.”

Bogaards says the shifting economics are already evident. “A couple of years ago, people said soybeans are a drag on our financial statements. It looks like almost the opposite right now.”

Even so, Bogaards is cautious about making long-term decisions based on short-term signals. “I can change acres right now, but by next fall, it might be the worst decision. I think you have to go with your rotation and stick with it.”

Pitstick links his long-term outlook to fuel sector growth, noting that both corn and soybeans increasingly function as energy crops.

“Some of the most profitable years of my career were when we had high fuel prices because we were also a fuel crop,” he says. “I have some optimism that these high fuel prices will cause some demand and increase our crop prices.”

For now, both farmers say their immediate job is to manage through 2026 while keeping their options open. With high costs for fertilizer, fuel, and machinery, they see expanded demand as the only realistic path forward.

“It is just survival at this point,” Bogaards says. “We just have to make sure we can survive and keep plugging through it.”

Corteva Unveils Executive Team Lineup For Its Two-Way Company Split

Tue, 14 Apr 2026 14:58:00 GMT

Corteva Inc. has reached a pivotal milestone in its corporate restructuring, announcing the executive leadership teams that will guide its transition into two independent, publicly traded entities.

The separation, which will result in the formation of New Corteva and SpinCo, is expected to be finalized in the fourth quarter of 2026.

New Corteva: A Focus on Crop Protection

Luther “Luke” Kissam has been appointed as the future chief executive officer of New Corteva, the entity that will retain the company’s crop protection portfolio. Kissam is scheduled to join the firm on June 1 as CEO.

Corteva’s Greg Page says the company board of directors selected Kissam following a global search, citing his ability to drive growth through innovation. Page notes that Kissam’s history of leading public companies and delivering market-focused solutions will benefit farmers and shareholders alike, according to a company press release.

Kissam brings a background in both agriculture and specialty chemicals to the new role. He previously served as the chairman and CEO of Albemarle Corporation and held legal and executive positions at Monsanto and Merisant Company.

Joining Kissam at New Corteva in key leadership roles will be:

Jeff Rudolph, chief financial officer
Brook Cunningham, chief commercial officer
Ralph Ford, chief integrated operations officer
Reza Rasoulpour, chief technology officer
Jim Alcombright, chief digital and information officer

SpinCo: Advancing Seed and Genetics

The second entity, provisionally named SpinCo, will operate as a standalone seed and genetics company. This business will focus on elite germplasm and cutting-edge biotechnologies, including gene editing and molecular breeding for row crops.

Current Corteva CEO Chuck Magro will transition to the role of SpinCo CEO at the time of formal separation. Magro says SpinCo’s success will be built on technological investments that allow farmers to increase yields in row crops and potentially new markets.

Along with Magro, the leadership team for SpinCo will include:

David Johnson, chief financial officer
Judd O’Connor, chief commercial and operations officer
Sam Eathington, chief technology officer
Audrey Grimm, chief people officer
Brian Lutz, chief digital and information officer
Jennifer Johnson, chief legal officer

Young Farmer Bets On ‘Lightning In A Tank’ To Tame His Fertilizer Bill

Thu, 09 Apr 2026 19:39:22 GMT

Farmer talk at the coffee shop often follows a predictable script: weather, grain prices and the eye-watering cost of inputs. But Carson Kahler, based in Martin County, Minn., is giving viewers of his 6th Gen Farmer videos on YouTube something more unique to discuss.

He’s decided to manufacture his own nitrogen.

“Starting my farming journey, I’m quickly realizing that there are certain things that I have to look at differently than a lot of other farmers do,” Kahler says. “One of those is the increased price in fertilizer and other inputs.”

While most corn and soybean growers are writing checks to their local co-op for all their nitrogen, Kahler is standing in his family’s machinery shed next to something he calls an “ugly conglomeration” of tanks and hoses. It’s a Green Lightning machine, a system that essentially tries to bottle a thunderstorm.

The Science Of The Spark

The technology behind the machine is an attempt to harness one of Mother Nature’s phenomenons. During a thunderstorm, a lightning strike generates enough heat and energy to break the incredibly strong triple bond that holds two nitrogen molecules together in the atmosphere. Once freed, the nitrogen atoms bond with oxygen and dissolve into falling raindrops. The result is a natural, nitrate-rich “fertigation” from the sky.

Kahler’s machine seeks to replicate this process in a controlled environment. By forcing compressed air, water, and electricity through a small chamber, it creates a miniature, continuous lightning storm. The output is water “high in nitrates” that can be stored and applied directly to the field.

For Kahler, the initial investment this past year was a calculated risk. Between the machine itself, the reverse osmosis unit to ensure water purity, the tanks, and the plumbing, he has approximately $10,000 in the system. His current unit is the smallest version available, rated to produce about 6,000 gallons of nitrate water annually. According to the manufacturer, that volume is equivalent to roughly 18,000 pounds of nitrogen.

However, as a young farmer who values data over marketing, Kahler isn’t taking those numbers at face value. “I took a sample out of one of my storage tanks and sent it over to the lab, and sure enough, it has nitrate in it,” he confirms. But knowing it’s there and knowing how the crop will react to it are two very different things.

Navigating Farmer Skepticism

Online, the reputation of Green Lightning is mixed. On forums like AgTalk, some farmers swear by it, while others say it’s a scam.

Much of the early failure associated with the technology stemmed from growers trying to use the nitrate water as a 1:1 replacement for traditional synthetic nitrogen. Research from Precision Planting’s PTI (Precision Technology Institute) Farm in Pontiac, Ill., backed up these concerns.

Precision Planting researchers have conducted a variety of tests on the Green Lightning technology at its Precision Technology Institute Farm based near Pontiac, Ill. More Info

(PTI/Carson Kahler)

Kahler points to data showing that in 2024, using the product as a total nitrogen replacement resulted in a nearly 45-bushel-per-acre yield hit, with similar disappointing results in 2025.

“When it first came out, a lot of people were thinking of it as a nitrogen replacer,” Kahler says. “But based on my research, that’s not the case.”

A Three-Pronged Strategy

Rather than asking the machine to do the impossible, Kahler has developed a strategy where the green lightning water acts as a supporting player — a utility player in his nitrogen lineup. He has identified three key areas where the product might provide a good ROI.

1. In-Furrow Advantage: Kahler modified his 12-row planter with two small tanks and a simple electric pump to apply the product in-furrow. One of the primary benefits of the nitrate water is its lack of salt.

“You don’t need to worry about burning the seed, burning the crops, creating a salt stress,” he says. “Also, if I have a leak or a spill or something, it’s not going to corrode my planter.”

He plans to run about 5 gallons per acre in-furrow, potentially pairing it with biologicals like Novonesis Torque IF. Based on PTI trials that showed a 3.5- to 5-bushel bump, Kahler is optimistic about the synergy.

2. Sidedress Blend The second pillar of his plan involves blending the product with UAN (28% or 32%) during sidedress. While the product performs poorly on its own, studies have suggested that when mixed with traditional nitrogen, it can enhance uptake. Kahler is planning a 70/30 ratio of UAN to green lightning.

Beck’s Hybrids 2025 research shows Green Lighting can replace a significant percentage of UAN:

Trial Insights: Beck’s PFR data shows that using Green Lightning as a starter (2x2x2) followed by a UAN sidedress was highly effective, yielding 207.6 Bu./A. However, when Green Lightning was used to replace the entire sidedress pass (UAN 2x2x2 followed by Green Lightning at V3), yields dropped significantly to 186.1 Bu./A.
Best Use Case: It is currently best utilized as a supplemental nitrogen source or to replace 25% to 55% of synthetic nitrogen. It excels as a “spoon-feeding” tool through foliar applications rather than a single bulk replacement for high-rate soil applications.

3. Water Conditioner: Perhaps the most overlooked benefit of the Green Lightning system, Kahler notes, is the water quality itself. Because the process starts with reverse osmosis water and ends with a product that has a pH of roughly 2.7, it could serve as an ideal carrier for fungicides.

“If you go and use a water that has a pH of 9, for example, the half-life of that fungicide… can go down to 2 minutes,” he explains.

By using the highly acidic, pure nitrate water as a carrier, he hopes to maximize the effectiveness of his chemical passes. “The water… is very pure, so it’s going to be able to be absorbed into the plant leaf a lot better than if you just took some well water and threw some AMS in it,” he estimates.

Dollars And Cents Have To Add Up

For Kahler, the math has to work. With electricity and water costs estimated at roughly 4 cents per gallon — or about 20 cents an acre — the operating costs are negligible compared to traditional starters that can run $20 to $30 per acre.

He is also being disciplined about his “nitrogen bill.” He doesn’t credit the green lightning for his total nitrogen needs in his primary calculations, treating it instead as a bonus or a conditioner. This conservative approach prevents him from under-applying traditional nitrogen and risking significant yield loss.

Despite the hurdles, Kahler remains a realist with an optimistic streak.

“If you add up all the small bushel increases from planting to fungicide, I think that there is a lot of potential efficacy for this product,” he says.

As the season progresses, Kahler will be watching his check strips and his storage tanks. He even has a safety valve in his contract that allows him to return the machine mid-summer if the results aren’t there. But for now, the 6th Gen Farmer is betting on the lightning.

“I’m pretty excited,” he says. “Sure hope it does good.”

‘If You’re Still Farming, You’ve Already Done Most of It’

Thu, 09 Apr 2026 14:26:35 GMT

On Chad Ingels’ northeast Iowa farm, every pass across the field is under the microscope as he fights to keep tight margins from slipping into the red.

“Oh, it’s tough,” Ingels said during an AgriTalk Farmer Forum discussion on Wednesday. “I think we’re going to have to really look at in-season passes that we planned to do. Maybe we’ll have to cut back one or two of those.”

Ingels, who splits his time between the farm and the Iowa Statehouse in Des Moines, says he can’t afford to simply slash expenses without weighing the risk to corn and soybean performance.

“You don’t want to impact yield,” he says. “You really want to take a look at what your return on investment is going to be on those passes.”

Across the Midwest, farmers like Ingels and Wisconsin grower and United Soybean Board director Tony Mellenthin are grappling with what they both describe as an “input price problem.” Corn and soybean prices have improved modestly from their lows, but fertilizer, pesticides and other inputs remain stubbornly high.

“I don’t think we necessarily have a corn or soybean price problem,” Mellenthin told AgriTalk Host Chip Flory. “We really have an input price problem, and until that can kind of get that addressed and fixed, that’s what I’m more concerned about than the price of corn and beans.”

Squeezing More From Every Dollar

On Ingels’ operation, the immediate response to high input costs is a sharper pencil and a more disciplined marketing plan.

In the field, that means reassessing every in-season trip across the crop. He’s eyeballing fertilizer or crop protection passes that might have been routine in good years, but now must clear a stricter bar: Will they pay?

On the balance sheet, Ingels says the focus turns to risk management and pricing discipline.

“Then it’s going to get to the marketing side,” he says. “We need to really do a better job of marketing corn and beans and — if we get a price run up — protect that run up so we can take advantage of it.”

The livestock side of the farm, he adds, is helping stabilize the operation, though it’s no windfall.

“The hog side is better than the crop side, but it’s not anywhere near like the beef side has been,” Ingels explains.

His hogs are sold into a specialty market through Niman Ranch, which ties its base price to grain and input costs.

“They’re setting a good base for us based on the corn and bean prices and our input costs,” Ingels says. “As we look out in the futures, the commercial price last year got higher than our base price, and so they adjusted our contract to say, ‘Hey, you’re going to get the better of the base price or the increased commercial price if the commercial price is higher.’”

That kind of contract flexibility, Ingels suggests, is one way the broader ag industry can help farmers weather volatile cost structures.

‘Not A Whole Lot Left To Do’

In western Wisconsin, Mellenthin says most of the fat has already been trimmed from farm budgets.

“If you’re still farming today, you’ve already done most of it, so there’s not a whole lot left to do,” he says. “There’s a little bit of tweaking to do, but I wouldn’t say there’s really any cuts to do.”

Instead of dramatic reductions, Mellenthin is stretching out capital decisions and switching to lower-cost inputs. That includes extending machinery trade cycles to delay big-ticket purchases and substituting generic fungicides for name-brand products when performance is comparable.

On the fertility side for corn, Mellenthin’s farm has been managing its nitrogen use through smaller, more targeted applications.

“We’ve been doing that for over a decade now,” he says. “There’s some of our ground that gets four passes of nitrogen.”

Recently, he’s begun to lean into alternative nitrogen sources to reduce dependence on high-priced synthetics. He points to biological products as one example.

“We have started utilizing some Pivot Bio,” he notes. “We haven’t seen a yield reduction, while at the same time reducing synthetic nitrogen, but we haven’t seen a yield gain, either. So I think we’re able to maintain there. And this year, that was the cheapest form of nitrogen a guy could buy.”

Policy and Industry: What Farmers Want Next

While individually they work to control what they can, both Ingels and Mellenthin are looking upstream — to input suppliers, processors and policymakers — to tackle what they can’t fix alone.

Regarding policy, Ingels points to the impact of global conflict and trade policy on fertilizer costs.

“There’s still some concerns out there with the war and how that’s impacted fertilizer prices going forward,” he notes. He adds that the greatest worry may lie beyond the current season to 2027, as farmers consider the next round of purchases.

During the discussion, Flory referenced efforts by the National Corn Growers Association and other ag organizations to push the administration to remove countervailing duties on phosphate imports from Morocco — one example of how farm groups are trying to pull down input prices through policy changes.

Ingels says those kinds of structural issues in fertilizer pricing could ultimately have more impact on future acreage decisions than anything farmers can do on their own fields this spring.

Demand, Renewable Fuels and Market Signals

Both farmers also stressed the importance of growing demand for the crops they produce, to help offset stubbornly high costs.

From his seat in the Iowa House, Ingels is backing measures aimed at strengthening markets for corn and soybeans, including renewable fuels. He references the Iowa Farm Act, saying it would increase the cap on the renewable fuels infrastructure fund grants to retailers from $100,000 to $150,000, and also help finance upgrades so more stations can offer E15 and higher ethanol blends.

“Retailers are taking advantage of that,” Ingels says “A few years ago, we had an E15 bill that went through… It certainly incentivized that all retailers handle E15 over time. And so this fund is being utilized all the time, and we’re trying to get to those last bit of retailers that maybe their costs are higher.”

At the federal level, though, Ingels is frustrated with delays on year-round E15 approval.

“This is the most frustrating thing I think the federal government has done to us,” he says. “They just keep kicking this down the road. We need to get it done.”

For soybean growers, Mellenthin is looking for similarly clear, long-term signals on low-carbon fuels.

In Wisconsin, he notes, lawmakers and the governor have already taken a supportive step by promoting “soy-based firefighting foam” to replace PFAS-based products. Nationally, Mellenthin wants to see the same kind of certainty for biomass-based diesel and other soy-driven fuels.

“We’ll take the good news when we can get it,” Mellenthin says of recent positive developments for biomass-based diesel. “Hopefully that could give a little certainty so infrastructure and investments can maintain being used.”

Relay Cropping System Lowers Input Costs, Raises ROI

Wed, 08 Apr 2026 20:57:07 GMT

Standing at the edge of a wheat field that will never break yield records, Jason Mauck explains that is exactly the point.

Instead of chasing trophies, the Gaston, Ind., farmer and CEO of Constant Canopy has spent over a decade turning wheat into a biological workhorse designed to support his soybean crops and, ultimately, protect his bottom line.

“It’s about economics,” Mauck says in an April 5 post to X.

Made some infographics tonight to explain our relay wheat system.

The main idea is we can grow 70 bushel wheat and 70 bushel soybeans and make about $250 more revenue per acre than pushing wheat yields up over 100 bu/ac and double cropping them.

We also save over $150 ac in… pic.twitter.com/ClmkKt1Jsq
— Jason Mauck (@jasonmauck1) April 6, 2026

By rethinking the traditional hierarchy of his fields, Mauck has engineered a relay system where wheat plays the perfect supporting actor, setting the stage for his soybean crop to take the lead and shine.

Rethinking Wheat’s Role On The Farm

Mauck’s strategy starts with a mental shift many growers may find uncomfortable: he does not try to push wheat past 100 bushels per acre.

“That takes too much time, too much sunlight,” he says. “You see your revenue is a lot less pushing wheat, selling 60 pounds of crop at a cheaper commodity price.”

Instead, he looks at how wheat and soybeans can perform together in the relay system — wheat first, then soybeans taking over as the season progresses. As wheat yields are dialed back, more resources open up for the beans.

“As your wheat yields go down, it creates space and opportunity and more water for beans,” Mauck explains.

He illustrates the benefit of the relay approach with a comparison. In one scenario, when wheat was pushed to yield 110 bushels, his soybean yields lagged. In a second scenario, both crops delivered yields of about 70 bushels.

“The main idea is we can grow 70-bushel wheat and 70-bushel soybeans and make about $250 more revenue per acre than pushing wheat yields up over 100 bushels per acre and double-cropping (soybeans),” he says in the post on X.

“We also save over $150 an acre in costs due to less wheat and soybean seed, less nitrogen… p+k, less fuel at harvest… and maybe the best thing is we can leave the field after wheat harvest and the soybeans are 2’ tall … not requiring baling/burning/ or tilling the straw,” he adds.

Mauck shows what his wheat crop looked like on April 5.

Lower Populations, Lower Inputs

To make the relay system work, over time Mauck has adjusted how he plants and manages wheat. One of the biggest changes has been to his seeding rate.

He plants a reduced wheat stand — about 425,000 seeds per acre — using only 18 rows of a 32-row planter. That leaves room in the system to intercrop soybeans while still establishing a solid wheat crop.

With fewer plants in the field, the wheat has access to more room and sunlight. Mauck notes that the result is heavy tillering which compensates for the lower population.

“We can get, you know, five, seven, nine wheat heads off of a single seed, and that helps drive the aggregate cost down to be about $150 [an acre] less than a corn crop,” he says.

Lower plant numbers also change how he fertilizes, reducing costs.

“It doesn’t take nearly as much nitrogen to push wheat to healthy vigor, with more light and less plants to feed,” he notes.

Wheat As A “Hybrid” Cover Crop

Another pillar of Mauck’s approach is timing of the crops. Wheat begins growing in February, well before soybeans go into the ground.

By early to mid-April, the wheat is about 10 inches tall. That growth is important, as the wheat pulls moisture out of the profile and conditions the field for the soybeans that will soon be planted.

Mauck says the wheat works like a “revenue-generating cover crop.” It creates a unique growing environment, allowing him to plant soybeans into a clean, conventional seedbed centered between the wheat rows. With a row of wheat positioned just inches to either side of the beans, the system naturally forms a solar corridor. This setup allows the wheat to manage soil moisture early on, while ensuring the soybeans have plenty of direct sunlight and space to flourish.

Once the wheat is harvested, the soybeans get an additional boost. “When we remove the wheat, it essentially prunes the biomass, allowing more light for the soybeans,” Mauck says.

In effect, wheat serves three purposes, he adds: it functions as a cash crop, a living cover that prepares the soil environment, and a temporary competitor to weeds before soybeans close the canopy.

He’s finding this system to be much more profitable… pic.twitter.com/L6lvsM0E31

Built For Controlled Traffic And Big Iron

While Mauck says the agronomics of the relay system are impressive, the secret to its scalability is mechanical precision. He uses a 40-foot “controlled traffic” system in fields, which essentially designates permanent highways for heavy machinery and protects the rest of the soil from compaction.

Here is how he breaks down the math of the wheel tracks:

The Triple Row (135-inch centers): The widest part of the layout is designed so the combine’s “fat tires” roll directly over a specific triple row of wheat.

The Inside Rows (60-inch centers): These are spaced to match the standard wheel tracks of a tractor, allowing it to pass through the field without touching the crop zone.

GPS Guidance: Thanks to GPS, every pass — from the sprayer to the harvester — follows the same lines year after year.

By concentrating all the heavy weight into these narrow, dedicated lanes, Mauck keeps the majority of his soils loose and aerated. It turns the logistical headache of “driving over two crops” into a streamlined, repeatable process that limits damage.

Eleven Years Of Refinement

Mauck has been working with the wheat–soybean relay concept for more than a decade, tweaking details as he learns how the crops interact and how the economics pencil out.

At this point, he is largely satisfied with the agronomics and structure of the system. The next frontier, he believes, is adding more precision to how he applies inputs.

“The only change that we can make is getting equipment to where we can band spray, we can sidedress the wheat when we plant the beans, and we can do a little bit more with the system,” he says. “But I’m very happy with the agronomics that we’ve got this year. Really looking forward to how this will play out as we go forward.”

Mauck believes his experience offers a different way to think about having small grains and soybeans in the same field. Rather than treating wheat as a standalone crop or a cover that must be terminated, he uses it as a living partner that hands off moisture, light and space to soybeans at just the right time.

The takeaway for other farmers, he says, is straightforward: focus on profit, not just bushels, and let each crop in the system do the job it’s best suited to do.

Defend Every Bushel With A Proactive Disease Plan

Wed, 08 Apr 2026 17:33:53 GMT

Addressing corn disease pressure in-season is rarely a matter of “if” and more likely “when.” Coming off heavy disease pressure from 2025, now is the time to put your plan together for how you’ll address challenges like northern corn leaf blight, tar spot and others this season. Plan your moves with these five recommendations, so you are ready to take action when disease pressure hits:

1. Use A Proactive Scouting Plan.

Success begins with staying ahead of disease, according to high-yield corn grower David Hula. “You have to stay proactive with your scouting and willing to go with earlier fungicide or even multiple applications, depending on what shows up,” he says.

While planning, consider the following:

1. Know your potential threats. Depending on the disease, some pathogens survive the winter on previously infected crop residue (e.g., northern corn leaf blight, tar spot). Other diseases move into northern growing areas on winds from southern locations (e.g., southern corn rust). For a suitable environment, many foliar diseases need warm, humid, and wet conditions to propagate.

2. Have your budget in place. Be ready for at least one in-season fungicide application. Use tools like the Newly Designed Fungicide ROI Calculators to guide your investment in products and applications. By inputting costs, market prices, and disease severity, these calculators provide research-based estimates of net benefits and breakeven probabilities, helping you make a more informed decision.

3. Delegate the scouting job, if necessary. If you cannot scout personally, assign the task to a family member, employee, or employ a professional service.

“Lots of great pest managers work in retail,” says Ken Ferrie, Farm Journal Field Agronomist. “Their success depends on you being successful also.”

2. Leverage Friends, Neighbors And Industry Expertise.

Don’t monitor disease pressure in a vacuum. Stay informed about what’s moving into your neighbors’ fields; track regional pressure by tapping into local agronomists and organizations like the Crop Protection Network.

Randy Dowdy, Hula’s partner in Total Acre, notes that in the Southeast, farmers are constantly receiving feedback from Extension and industry experts regarding southern rust.

Similarly, Elliott Henderson, who farms in Buchanan County, Iowa, has a group of farmers there that he connects with on a regular basis during the growing season.

“It’s a network of dozens of us farmers that call each other, bounce ideas off each other,” he says. “The things we’re talking about are often time-sensitive. It can be a daily thing.”

3. Select The Right Chemistry.

Applying the wrong product in the heat of battle with disease pressure is a common mistake. For aggressive diseases like tar spot or southern rust, Farm Journal Field Agronomist Missy Bauer recommends using “Cadillac” type chemistries — newer technologies that feature multiple modes of action.

To ensure you are using the right tool:

Consult Your Experts. Use the Crop Protection Network’s Fungicide Efficacy tables to see which products perform best against specific diseases.
Match Product to Problem. Ensure the product is labeled for your specific issue and is capable of handling high-pressure scenarios.

4. Optimize Applications for Maximum ROI.

If you need to apply a fungicide, make sure it delivers the results you need.

“It’s all about coverage,” Dowdy says. “Drone applications can be fine, but no matter what you do, if a guy is spraying two to three gallons, and you compare it to a ground rig spraying 15 to 25 gallons, I mean, there’s just no comparison in that coverage.”

Another aspect of coverage, Hula adds, is making sure the fungicide gets into the plant canopy far enough to have the desired effect. That becomes even more critical as the season advances.

“Fungicides have a tendency to work from the leaf they’ve come in contact with and move up,” Hula says. “So, if you’re trying to protect at least that ear leaf – and I like to protect the leaf opposite and below the ear – you’ve got to get penetration with that product.”

Hula says growers might have to spend a couple extra dollars to get sufficient volume for the product to get down below the canopy, if using a drone for application.

“If that’s what needs to be done, let’s do it,” he encourages. “If I’m spending $30 or more an acre, then I want to at least have the success that I’m paying for.”

5. Commit To Protecting Corn Through The Entire Season.

Modern corn genetics have significant “back-end” potential, enabling them to add yield through kernel fill late into the season. Hula and Dowdy advise against walking away from the crop early. They say evaluating fungicide applications during later reproductive stages can often yield a high return on investment.

D hybrids are of particular concern late-season, Ferrie says. These are hybrids that have kernel depth changes, positive or negative, based on populations and environmental conditions during the last 30 days of grain fill.

Missy Bauer, Farm Journal Field Agronomist in Michigan, zeros in on corn growth stage to guide uber-late-season fungicide applications.

“If I had a field that has no fungicide at all on it, and I had fairly heavy disease pressure from something like southern rust or tar spot, and I’m at early R4, I would still apply the fungicide,” she recommends.

Early Soybeans Benefit From Protection In Cold Soils

Tue, 24 Mar 2026 20:11:26 GMT

When the calendar says it’s still a little early for soybeans but field conditions are just right, growers face this increasingly common dilemma: plant and risk the outcome in cold, tough soils—or wait and risk missing the best window.

More farmers are deciding to go early. As they do, seed treatments and inoculants are playing a bigger role in helping growers manage the risks, reports Missy Bauer, Farm Journal Field Agronomist, based in south-central Michigan.

The Case For Inoculant Use

While soybeans naturally fix nitrogen through root nodules, the process depends on the presence of Bradyrhizobium bacteria. Inoculants introduce these essential microbes to maximize nitrogen fixation and crop performance.

Inoculants are most often useful, the Crop Protection Network (CPN) reports, when fields have no history of soybean production, or when the field has gone four or more years without being planted to soybeans.

Farm Journal Field Agronomist Missy Bauer says her field research in south-central Michigan indicates inoculant use can also be a net positive in “ultra early” soybean planting. She has spent the past three years evaluating Preside Ultra, a “super-concentrated” soybean inoculant.

“The results are pretty positive,” says Bauer. “We’ve seen good early growth all three years that we looked at this product.”

Three years of field testing show a solid return-on-investment for the inoculant.

Her data shows the product has added about 2.4 bushels per acre on average, delivering roughly $25 per acre in return for about $1.10 per acre more cost than a “standard” inoculant.

“I’ve been pretty happy with what we’ve seen with the enhanced early growth,” Bauer says. “I think the product pairs well with when I plant early, what we can do to get these beans going better knowing that they’re in a tough, cold environment.”

Seed Treatments Continue To Play A Valuable Role

When it comes to protecting early-planted soybeans, Bauer says seed treatments like Ilevo and Saltro still earn a place in growers’ plans as important production tools.

“While we aren’t continuing to research the Ilevo, we have that good history of Ilevo seed treatment and still recommend growers use it or Saltro,” she says.

For Bauer, that “good history” matters. Even without continuous new trials every season, a solid base of multi-year data gives her confidence to keep recommending both products, particularly when growers want to push soybeans into colder soils ahead of the traditional planting window.

Her message to farmers is that early planting doesn’t have to mean planting unprotected. With a strong track record and comparable performance in her trials, she views Ilevo and Saltro as dependable options when the goal is to capture the yield upside of early soybeans while managing the risk that cold, challenging environments can bring.

While Farm Journal Field Agronomist Missy Bauer says she is not conducting further testing on Ilevo or Saltro, she has confidence in their performance in soybeans, especially in early-planted crops.

(B&M Crop Consulting, Coldwater, Michigan)

The CPN says the benefit of a seed treatment is most evident when reduced soybean seeding rates (140,000 seeds per acre or less) are used. In many regions, the minimum plant stand for highly productive soils is 100,000 plants per acre. Because farmers want to minimize input costs while maximizing yield, they may reduce their seeding rates and use seed treatments to help protect the stand, CPN reports.

Next Steps For Your System

For most soybean growers, adopting a different inoculant or seed treatment won’t require a major overhaul. In many cases, it’s a conversation with a seed dealer or custom treater, Bauer says.

Four next steps she recommends:

Talk to your seed dealer about the inoculant and seed treatment options they offer and the potential benefits.
Review local data from plots in your area, especially where beans were planted early.
Match products to your planting plans — early planting into cold soils typically justifies a more robust treatment package.
Consider a strip trial for evaluation purposes. Compare your standard package against an upgraded inoculant or seed treatment.

For farmers looking to protect their early-planted soybeans — and squeeze a few more bushels out of every acre — upgrading the inoculant and revisiting their seed treatment package may be one of the simpler, higher-return changes they can make, Bauer 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.

Elevated Corn Rootworm Pressure Projected For The Midwest

Wed, 18 Mar 2026 19:51:42 GMT

The “billion-dollar bug” is sharpening its teeth for 2026. Bayer CropScience reports corn rootworm pressure could be significant this year across major corn growing areas.

Based on 2025 beetle capture data from 555 monitored fields, the company projects medium to high rootworm pressure for the upcoming growing season in much of the Midwest:

31% of the corn fields sampled in 2025 had counts exceeding the economic threshold of 2 beetles/trap/day, which was 2% higher than 2024 fields (29%), 22% less than 2023 and 2022 fields (53%), and 7% less than 2021 fields (38%).
46% of the continuous corn fields sampled in 2025 were above the economic threshold, which was up 3% from 2024 (43%), down 25% from 2023 (71%), down 28% from 2022 (74%), and down 6% from 2021 (52%).
17% of the first-year corn fields in 2025 were above the economic threshold, which was 1% higher than 2024 (16%), 3% higher than 2023 (14%), up 7% from 2022 (10%), and equal to 2021 (17%).

On a broad scale, Bayer reports that rootworm larval populations — and consequently the risk potential from all CRW species this season — are likely to be elevated in fields in northern Illinois, south central Illinois, western Iowa, eastern, southeastern, and southwestern Nebraska, eastern and southeastern Wisconsin, and northern Colorado. Read the full report here .

Rootworm larvae feeding on corn roots compromise the plants’ structural integrity and can slice yields in affected fields by as much as 45%.

How Two CRW Variants Beat The Corn-Soybean Rotation

“CRW beetles are very, very adaptable to many of the things that we throw at them,” says Ashley Dean, Iowa State University Extension field crop entomologist.

She says CRW is forcing many row-crop growers to rewrite their management playbooks to address the pest better, especially variant populations.

Dean reports that the “variant” label describes two distinct genetic adaptations of corn rootworm:

Northern Corn Rootworm (Extended Diapause): These small green beetles have learned to hit the “snooze” button. Instead of hatching the following spring, their eggs remain dormant in the soil for two or more years—sometimes up to five. This allows larvae to emerge exactly when a field rotates back to corn.
Western Corn Rootworm (The Soybean Variant): These yellow-and-black striped beetles have developed a behavioral shift. Instead of staying in cornfields to lay eggs, females migrate to soybean fields to deposit them. When that field is planted to corn the next season, the larvae are already waiting in the soil. “These variants have essentially lost their fidelity to corn when they’re laying eggs,” Dean notes in a webinar.

These maps give approximate locations for western and northern corn rootworm variants.

A Multi-Pronged Management Strategy

Addressing corn rootworm effectively requires farmers use a localized, field-by-field strategy, says Jim Robinson, chief technology officer for Rob-See-Co. Because geography, soil, and history vary, growers should work with agronomists to tailor traits and stewardship practices to their specific acres rather than relying solely on regional forecasts, he advises.

Here are four additional recommendations Extension and industry advise farmers use in areas with expected high populations of CRW this season:

Make Root Scouting Non-Negotiable: Dig and rate roots in every field—continuous or rotated—to understand your baseline pressure. For assessing damage, use the interactive node-injury scale from Iowa State available here .
Consider Longer Rotations: In areas with heavy Northern corn rootworm extended diapause, adding a third crop like oats can break the cycle, Dean says.
Strategic Use of Bt and Insecticides: While Western corn rootworm has shown resistance to all four Bt traits in some areas, these tools still have a place. However, Iowa State suggests choosing either a Bt hybrid or a soil-applied insecticide rather than using both as “insurance” unless pressure is extreme.

To help farmers make informed decisions, Chris DiFonzo, professor & field crops entomologist at Michigan State University, provides the Handy Bt Trait Table for U.S. Corn Production , a valuable resource that outlines available Bt traits, their targets, and other key information.

Leave a Check Strip: When testing a new transgenic hybrid or insecticide in first-year corn, leave an untreated strip. This is the only way to verify if the treatment provided a return on investment.

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.

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.”

Making the Invisible Seen: How Artificial Intelligence is Unmasking Soybean Nematodes

Thu, 12 Mar 2026 18:20:15 GMT

Nematodes are nearly impossible to see with the naked eye, but their impact on soybean yields is about to come into clear focus. Thanks to a new digital tool from Syngenta called Nema Digital, the invisible is becoming visible.

The technology uses satellite imagery and artificial intelligence (AI) to scan soybean fields for crop stress that mimics nematode damage. According to Kirt L. Durand, PhD, Syngenta digital ag solutions R&D manager, the goal is to bridge the gap between what a farmer sees and what is actually happening in crops beneath the soil surface.

“Farmers might not even know that they’re losing yield due to this microscopic pest, and that’s what this technology is really all about – providing awareness,” he says.

How the Algorithm “Thinks”

Nema Digital is a satellite-based algorithm trained to distinguish nematode pressure from other common crop-production headaches like nutrient deficiencies, soil compaction, or simple field anomalies. By analyzing multiple years of historical satellite data, the system searches for specific patterns that match known nematode behavior and damage.

For farmers and retailers, the process is designed to be hands-off. Syngenta only needs basic information—field boundaries and crop history—much of which is already automated for those using the Syngenta Cropwise platform.

“Really, most of this is very automated at this point, very little input required from the farmer,” Durand says.

Once the data is incorporated, the AI filters out any visual noise.

“When we get done, it narrows it down and says, with high accuracy 90% of the time, this is going to be a problem caused by nematodes,” Durand says.

The Limits of the Soil Probe

While traditional soil sampling has been the standard tool to check for nematodes, Durand notes research shows how easy for a sample to miss them.

He points to research from Iowa State University nematologist Greg Tylka, which shows that nematode egg counts can vary wildly just a few feet apart. You could pull a core sample that looks clean, while two feet away, thousands of eggs are feeding on your profits.

“You can imagine that if you’ve been looking for nematodes simply by soil sampling, it’s not accurate enough,” Durand says.

Protecting the Bottom Line

The financial stakes of nematode pressure are high. Research from The SCN Coalition indicates that nematodes commonly cause a 25% yield loss in infected soybean fields, but in severe cases—or when multiple species like root-knot and soybean cyst nematode (SCN) team up—that loss can skyrocket past 70%.

“When you have multiple species of nematode present, the impact on soybeans tends to be even more severe than just SCN alone,” Durand says.

One way Durand says farmers and retailers will be able visualize that impact is to pair Nema Digital results with yield maps. By overlaying the nematode output on harvested yield, Durand says growers and retailers often can see a clear connection between areas flagged for nematode pressure and zones of lower yield.

“You can actually see in the field where we identify that you have a nematode problem, and if you put a yield map on it, we’ve seen that those areas tend to have lower yields versus the average yield for that entire field,” he says.

Commercial Launch In 2027

While Nema Digital is being piloted through select retail partners and their farmer customers in 2026, Syngenta expects a broad commercial launch next year.

For soybean growers wondering about the return on investment for the technology, Durand stops short of assigning a specific dollar figure. But he stresses that identifying nematode pressure is the first step to protecting yield with available tools, including Syngenta’s new broad-spectrum nematicide seed treatment, Victrato.

Ultimately, Durand’s message to growers is simple: don’t confuse “invisible” with “absent.”

“The issue is out there,” he says. “We want to help farmers be aware of it and what they’re losing.”

Is A Nitrogen Inhibitor Worth The Cost?

Wed, 11 Mar 2026 20:34:06 GMT

Nitrogen inhibitors, often referred to as stabilizers, are increasingly used by farmers looking to protect their fertilizer investments and maintain yields amid increasingly erratic weather.

There are two primary types of nitrogen inhibitors in the marketplace today: urease inhibitors and nitrification inhibitors.

Nitrification inhibitors such as nitrapyrin, DCD, and pronitridine have been developed to delay the conversion of nitrogen fertilizers into nitrate, according to Fabian Fernandez, University of Minnesota Extension nutrient management specialist.

“The reason we want to delay transformation to nitrate is that nitrate can leach below the root zone or be denitrified if there is excessive precipitation,” Fernandez reports.

University of Minnesota researchers have evaluated nitrogen inhibitors as well as numerous enhanced efficiency fertilizer products.

(Fabian Fernandez)

Urease inhibitors such as NBPT and NPPT delay the conversion of urea into ammonia. “We want to prevent nitrogen transformation to ammonia as this too will end up in the environment and not available to the crop. In this case, though, the loss happens as ammonia goes off as a gas to the atmosphere,” he says.

As the 2026 season gets underway, here are two key reasons to consider using a nitrogen inhibitor:

1. Maximize Nitrogen Efficiency

Inhibitors delay the conversion of ammonium-N to nitrate-N, which reduces nitrogen loss via leaching and denitrification, increasing N availability for crops and boosting yields by 5% to 12%, according to Bob Nielsen, Purdue University agronomist and professor emeritus.

Furthermore, because inhibitors slow down the nitrogen conversion process the nutrients stay in the root zone and available to crops longer – up to eight weeks depending on the product used, according to Corteva Agriscience.

2. Keep Nitrogen In The Field

Early in the season, heavy rains and warming soil temperatures can contribute to significant nitrogen loss. With spring applications, research shows soil can lose more than 20% of its total nitrogen after just one or two rain events, according to Heather Vosburgh, nitrogen stabilizer strategic account manager, Corteva Agriscience.

The concern for potential N runoff is why Tyler Wiltfang , a fourth-generation farmer, near Oregon, Ill., says he uses an inhibitor in early spring, prior to planting corn.

“Some of our fields are very close to a creek, and we don’t want that [nitrogen] going other places,” says Wiltfang, who grows corn and soybeans on the same land his great grandfather bought in 1929.

“It’s important to be thinking about the environmental impact, because we have to take care of the ground to grow our crop,” Wiltfang adds. “If the soil isn’t up to par, and we’re not doing our part, we’re not going to have a good crop using a nitrogen stabilizer, such as Instinct.”

With meteorologists predicting an active weather pattern across the Eastern Corn Belt this spring delivering excess moisture that could delay early planting, farmers in those areas might want to be prepared to use an inhibitor.

When To Pass On Using An Inhibitor?

There’s at least one scenario when you don’t need to use a urease inhibitor — when you make a broadcast application of urea that is immediately incorporated by tillage at least 2” in the soil, Fernandez reports in this online video and article.

“If you were concerned about nitrogen loss from a pre-plant application, I would not use urea-ammonium nitrate (UAN) and include a nitrification inhibitor to protect the investment,” he says. “While the nitrification inhibitor will provide protection, 25% of the application is already nitrate in this fertilizer source and the inhibitor will do nothing to protect nitrate from leaching or denitrification loss. It would be a much better idea to use the inhibitor with a urea application.”

On the other hand, Fernandez says using a urease inhibitor when urea is surface-applied in a high crop-residue field, or a nitrification inhibitor or polymer-coated urea in fields or portions of fields that tend to be wet, is most likely to increase the chance that you see a benefit from your investment.

Agronomic specialists like Fernandez emphasize that nitrogen stabilizers are not stand-alone solutions. They are most effective when integrated into a broader nitrogen management strategy that includes realistic yield goals, soil testing, attention to soil type and drainage, and thoughtful decisions on application rate and timing.

Smart Strategies for Planting in Wet or Dry Conditions

Tue, 10 Mar 2026 20:47:18 GMT

There are few mistakes that you can’t overcome, given enough time. But problems at planting time set the stage for an entire season’s worth of trouble.

Many, if not most, planting problems result from failing to adjust practices and equipment to fit soil and weather conditions, says Farm Journal Field Agronomist Ken Ferrie. Since you can’t know what the weather will do, you have to plan for various scenarios.

What If It’s Dry?

Ferrie has one rule: Don’t plant corn into dry soil, hoping to “rain it up.”

“Putting corn in dry soil, and not having it germinate in timely fashion, can be a disaster for your stand,” he says. “If you do spring tillage too far ahead of planting, that lets the soil dry out. Don’t let your soil finisher get too far ahead of the planter in a hot, dry spring.”

In a dry situation with conventional tillage, use row cleaners to push away clods in front of the planting units. “If you crush clods with your depth wheels, you’ll put dry soil around the seed,” Ferrie says. “Use your row cleaners as a clod roller.”

In either no-till or conventional tillage, use row cleaners to move residue out of the way. “Normally, a little residue is no big deal,” Ferrie says. “But if it’s dry, residue tucked into the seedbed wicks moisture out of the furrow, away from the seed.”

Running out of planting moisture in no-till is rare, but it can happen in sandy soil or if you fail to kill a cover crop on time, Ferrie notes. “It can happen when strip-tilling in coarse soils, if you are not timely with your planter,” he says. “In strip-till, you may have to go off the strip and no-till the seed beside the strip.

In tough conditions, with no rain in the forecast and you know it will be even drier in 10 more days, use your row cleaners to move away the dry soil. Hopefully, this will get you closer to some moisture where you can place the seed, Ferrie advises.

This carries risk, though. “If you applied a pre-emergence herbicide, there will be no herbicide left in the row,” Ferrie says. “Have a plan in place to control weeds in the row.”

If you “plow down to moisture” in strip-till or conventional tillage, you will actually be planting in a valley. “If the weatherman turns out to be wrong and you get a toad strangling rain before the corn comes up, the corn will get buried and you’ll have to replant,” Ferrie says. “But at least you’ll have moisture to replant in.”

What If It’s Wet?

Unless you own a crystal ball, you need a plan for wet weather, too. “Don’t mud a crop into cold, wet soil unless you’re running up against the crop insurance date because of prolonged cool, damp weather,” Ferrie says.

Most often, you’ll have soil that, while fit to plant, is on the wet side. “In marginally wet conditions, the biggest problems I see are carrying too much down pressure on row units and being too aggressive with row cleaners,” Ferrie says. “That makes it difficult to close the slot. If you back off down pressure and let up on the row cleaners, you’ll often find that a field that seemed too wet to plant will plant nicely.”

Worries about maintaining seed depth are what make farmers too aggressive with down pressure. “That gets people in trouble in marginally wet conditions,” Ferrie says. “With today’s monitoring equipment, you can back off down pressure and know whether you’re maintaining depth control.”

A row unit functions sort of like a Jet Ski, Ferrie says. The faster you pull the planter, the more it wants to come out of the ground, so it takes more down pressure to maintain proper depth.

“In these marginal conditions, in order to stay on top of dry soil and plant through it without moving it, you may have to slow down the planter to maintain depth control,” Ferrie adds. “Slowing down from 5 mph to 4 mph is still faster than waiting for the field to dry out, so you can plant with more down pressure and a higher speed.”

In marginal conditions, stop the planter and adjust row cleaners, closing wheels and down pressure from field to field, Ferrie says.
One other time you might need to plant in wet soil is when you have wet spots in an otherwise dry field.

“It’s a time-sensitive issue,” Ferrie says. “If you’re in danger of missing the optimum planting period, and 80% of the field is ready but 20% is still wet, go ahead and plant. You’ll have yield loss in the areas that aren’t ready, but not as much as if you miss the optimum planting window on the 80%.”

If spots in a field are wet every year, consider tiling them. “If you improve timeliness over the entire field, you pick up yield everywhere, not just in the wet spots,” Ferrie says.

If you can’t improve drainage in those fields, set your planter for wet conditions. “Use spoked closing wheels to close the furrow,” Ferrie says. “Put scrapers on your planter’s depth wheels. Use a variable down-pressure system, so you can take the pressure off when planting through wet areas.

“Be conscious of planter weight in those fields. If you have a center-fill planter with starter fertilizer tanks, fill the hopper and tanks only partway. Keep the planter as light as possible.”

Give Extra Attention To Fertilizer Management

“In a dry year, be careful about applying starter in the furrow, even if you’re using a low-salt product,” Ferrie says. “If you’re worried about having enough moisture to germinate the corn, don’t put any salt in the furrow.”

If you apply anhydrous ammonia in the spring, allow at least two weeks between application and planting, and hope for a 2" rain. “In a dry spring, I’ve seen ammonia applied in February burn corn planted in April,” Ferrie says. “If you have auto-steer, you can use it to apply the ammonia and then plant between the ammonia strips.”

Here are a couple of other things to keep in mind if spring turns out dry: “Soil-applied herbicides need moisture to disperse in the soil and activate the active ingredients,” Ferrie says. “Plan to scout more and apply rescue or cleanup treatments, if needed.”

In northern areas where primary tillage is done in the spring, do secondary tillage within hours after chiseling. “There will be no freezing and thawing to break up chunks and prevent them from turning into clods,” Ferrie says. “If they turn into clods, you’ll have to deal with them all season long.”

Whatever the weather brings, patience at planting is a virtue. “Don’t feel that you have to plant just because your neighbor is,” Ferrie says. “With today’s genetics, we have a wider planting window. Diversity in planting dates, as long as you don’t miss the optimum range, reduces pollination risk.”

Is Planting Always a Struggle?

If weather is cool and wet, you might have to fight to get corn planted during the optimum window—that’s normal. But if you struggle to finish on time every season, or if you find yourself starting earlier to finish on time, you might need to re-evaluate your equipment and manpower, says Farm Journal Field Agronomist Ken Ferrie. “Early planting is fine if conditions are right, but if you plant in wet soil in order to finish on time, you risk problems with stand establishment,” he says.

Consider the following pinch points to determine if your planting pipeline needs an update:

Timing. How much time do you have to get planting done? Your landgrant university or seed company can tell you the optimum planting window for your locality because it varies by area.

Ferrie suggests his Midwestern clients be able to plant their corn crop in five days, when conditions are right. “Of course, those five days may not come in one stretch. It may take a month to get five days of good planting conditions, depending on the weather,” he says.

Machine power. Is your planter sized for your acreage? “As farmers pick up acres, they may add a grain cart or a second combine but forget to upsize their planter,” Ferrie says. “Rather than a bigger planter, you may want a second one, so you can plant in two areas at once.”

Manpower. Consider hiring a custom operator to spray while your skilled employee plants. “You can hire people to do a lot of jobs,” Ferrie says. “But it’s difficult to hire someone to plant your crop on a timely basis.”

Use This 4-Step Checklist for 97%-Plus Waterhemp Control

Fri, 06 Mar 2026 19:44:09 GMT

In the constant battle to keep soybean fields clean, few weeds have proven as difficult for farmers to control as waterhemp.

“Last year, in 2025 we struggled a lot with waterhemp, and that’s a weed that’s going to continue to present problems for us,” notes Mike Hannewald, field agronomist with Beck’s Hybrids.

Seasonlong competition by waterhemp (more than 20 plants per square foot) has been shown to reduce soybean yield by 44%. Waterhemp emerging as late as V5 soybean reduced yields up to 10%, according to Take Action .

Hannewald’s message to farmers for 2026 is this: Controlling waterhemp isn’t about a single product or pass. It’s about designing a thoughtful, layered herbicide program that starts before the planter rolls.

Here is a summary of the four key practices he recommends:

1. Begin the season with clean fields.

The first principle is deceptively simple: start clean.

Hannewald advises using a burndown herbicide pass or properly set tillage if you’re in conventional tillage to completely remove existing weeds before planting.

“Make sure the tillage tool is actually set to tear the weeds out, checking that they’re fully uprooted and not just being knocked over,” he says.

2. Use a “three in the pre” herbicide application

Beck’s Practical Farm Research (PFR) data shows when three modes of action are used in a pre-emerge application to control waterhemp, 97% control was achieved and maintained 45 days after treatment.

“That residual can be either made after we do our tillage or combined with our burndown pass,” Hannewald says.

Adding a third site-of-action chemistry delivered an 8% boost over the use of two SOAs.

(Beck’s Hybrids)

Because there are many active ingredients available — and even more brand names — it’s easy to not succeed in getting three different chemistries in the tank. To help minimize confusion, Hannewald recommends tuning into the chemistry group numbers.

He recommends soybean growers use some combination of three herbicides from these four groups:

Group 2: Amino acid synthesis inhibitors, such as cloransulam.
Group 5: Photosynthesis inhibitors, such as metribuzin.
Group 14: Cell membrane disruptors, such as sulfentrazone
Group 15: Seedling root growth inhibitors, such as metolachlor, acetochlor and pyroxasulfone

“Now, if you are planting XtendFlex soybeans and you’re using an approved version of dicamba as your burndown, dicamba does have residual value, so that counts as one of the three,” Hannewald says. “But if you’re using 2,4-D on Enlist soybeans, 2,4-D does not have residual value, so that doesn’t count. You need to add three additional modes of action there.”

For more insights on specific Group Numbers, the MOAs, and product brand names, be sure to check out the 2025 Take Action Herbicide Classification Chart.

3. Make a post-herbicide pass prior to flowering

If building a strong pre strategy is partly about chemistry, the next step—timing the post pass—is about mindset. For many soybean growers, waiting to spray until weeds are obvious is a common course of action. Hannewald believes it’s time to change that thinking.

“This is the biggest mindset shift for us to stay ahead of waterhemp, and that’s spraying your soybeans before flowering,” he says.

In practical terms, this means moving the post pass much earlier than many farmers are used to—often when the field appears relatively clean (e.g. around V3 rather than R1).

“In most cases, you’re probably going to be driving through the field thinking, ‘I don’t need to be out here at this point because there’s not much weed pressure, if at all,’” he says.

But targeting small weeds early, before the beans canopy, allows you to get good coverage and control. This is especially important if you’re going to spray glufosinate (Liberty), reports Isaac Ferrie, Crop-Tech Consulting field agronomist.

According to the label Liberty can be sprayed on LibertyLink soybeans from emergence up to the R1 growth stage (first bloom).

“That means once 50% of those plants out there have one flower on them, we can’t spray Liberty,” Ferrie says.

Another consideration is the impact of later herbicide applications on yield potential.

A PFR study that compared herbicide applications in soybeans at V3 to those made at R1 found the latter application caused a yield decrease.

“We saw losses of 1.2 bushels to 2.5 bushels per acre just from the R1 application stressing that soybean plant,” Hannewald explains. “Even though our beans are tolerant to these herbicides, it still takes energy for that soybean plant to process that herbicide, metabolize it, break it down and get rid of it, and that energy causes stress on the plant.”

A post application with glufosinate (Liberty) gets another chemistry in the weed-control mix, which helps stop weeds and the opportunity for resistance to build.

(Beck’s Hybrids)

4. Add an in-season residual with the post pass

Step four is adding an in-season residual to the post pass. This is what makes the early post pass work.

“At this point, we still have some soil visible, and when we add that in-season residual, it’s like you’re laying a blanket across that soil to stop late-emerging waterhemp from growing,” says Hannewald.

He adds that he likes using a Group 15 herbicide as the residual now, because they’re effective on small-seeded broadleaf weeds.

Hannewald says Beck’s PFR shows farmers get 6% additional control – going from 88% to 94% control of waterhemp at harvest – by adding the in-season residual.

“While 6% may not seem like a whole lot, that works out to 17.1 million fewer viable waterhemp seeds per acre going in our seed bank for the next year and future years,” he says.

Fewer weed seeds means fewer waterhemp to deal with the following year.

(Beck’s Hybrids)

In summary, Hannewald boils his recommendations for 2026 down to a four-step framework: start clean, layer three modes of action into the pre pass, move the post application earlier—before flowering—and add an in-season residual to carry the field through canopy and into harvest with fewer waterhemp.

He adds that soybean growers can adapt those four steps to their own equipment, weed spectrum and trait platforms, but the underlying strategy remains the same: think proactively, diversify chemistry, and protect yield potential for this year and in the future.

Next-Gen Herbicides Target Tough Weeds In Corn And Soybeans

Thu, 05 Mar 2026 18:43:22 GMT

Several companies have announced new weed-control tools for row-crop growers’ use in the upcoming season. Here is a brief summary of the technologies:

Helena Agri-Enterprises plans to give corn and soybean growers more weed-control options this season with the launch of Testament. The new herbicide provides early-season weed control and strong crop establishment in pre-plant and pre-emergence applications, according to Michael Cox, Helena products group brand manager.

The herbicide combines three active ingredients—saflufenacil, pyroxasulfone, and dimethenamid-p—to create a powerful defense against tough weeds. In trials conducted across diverse regions, including the Dakotas, the Texas Panhandle, and the Mid-South, Testament proved effective against Palmer amaranth, waterhemp, marestail, morningglory and annual grasses.

“Testament fills a gap by providing great weed control in areas where crop rotation sensitivity is a concern,” Cox says in company news release. “Its broad application rate allows you to customize it based on your specific soil type and how long you need the protection to last.”

Timing and Resistance Management

Cox notes one of the standout features of Testament is its versatility. It can be used during fall burndown, pre-plant, or pre-emergence windows. Because it offers generous plant-back restrictions, growers have more flexibility when dealing with unpredictable weather or changing planting schedules. Additionally, by using multiple modes of action, Testament helps farmers manage the growing challenge of herbicide resistance.

In addition to Testament, Helena announced the EPA registration of Sinister Nexus, a three-way soybean herbicide. While Sinister Nexus will have limited availability starting in 2026 (pending state approvals), Cox says it represents Helena’s ongoing commitment to expanding its portfolio of weed control solutions.

Growers interested in learning more about Testament or Sinister Nexus can visit www.helenaagri.com for availability in their state.

The Future Of 2,4-D From Nufarm

Nufarm announces its 2,4-D-based product Weed Master XHL is available for use in 2026. The product features Nufarm’s patented Dual Salt Technology and lower-volatility DGA dicamba.

Four key features of WeedMaster XHL:

controls 90+ annual and perennial broadleaf weeds
provides reduced volatility and is a low odor formulation
offers improved handling and tank-mix compatibility
delivers superior cold storage performance

BASF Introduces Engenia and Zidua Plus

BASF announces it has received notice from the U.S. Environmental Protection Agency (EPA) of federal registration for Engeniaherbicide for over the top (OTT) applications on dicamba-tolerant soybeans and cotton.

The new registration gives U.S. soybean and cotton farmers an additional tool to battle 200-plus weed species, including Palmer amaranth, waterhemp, kochia, morningglory and ragweed.

Stewardship is a critical component of any pesticide registration, and BASF says it continues to work with the EPA and state agencies to create national and state-specific training materials. The company will offer a suite of training options to ensure farmers and applicators understand the new Engenia herbicide label requirements.

On the horizon — potentially coming to U.S. farmers in 2026 — is new Zidua Plus herbicide. BASF says, upon registration, the herbicide will bring application flexibility, comprehensive weed control and residual endurance to soybeans with two modes of action. The product will be available for application from pre-plant through post-emergence.

First Dual Mode-Of-Action Classification

While not a new herbicide, FMC’s rimisoxafen has been classified by the Herbicide Resistance Action Committee (HRAC) as a dual mode of action herbicide, designated under HRAC Groups 12 and 32.

This is the first dual mode-of-action classification in HRAC’s history. The unprecedented classification recognizes rimisoxafen’s unique ability to simultaneously inhibit both phytoene desaturase (PDS) and solanesyl diphosphate synthase (SDPS), two critical biochemical pathways in weeds. The dual mode of action makes it far more difficult for weeds to survive and adapt, providing a critical new tool in the fight against herbicide resistance.

“HRAC’s historic classification of rimisoxafen validates the breakthrough nature of this technology,” said Seva Rostovtsev, executive vice president and chief technology officer, in a press release. “Studies show this molecule delivers control of palmer amaranth and waterhemp, giving farmers an effective solution against weeds that have become resistant to multiple herbicide classes. This is the kind of innovation growers need to protect their crops and their livelihoods.”

Rimisoxafen’s dual mode of action creates a significantly higher barrier to resistance development compared to single mode of action herbicides. Rimisoxafen is designed primarily for use in broadacre crops such as corn, soybean, cereals, pulses and sunflower, and will provide effective control of troublesome and resistant broadleaf weeds.

Could Strip Tillage Be Your Key To Lower Costs And Higher Yields?

Mon, 02 Mar 2026 21:51:29 GMT

Strip tillage has provided Ron Verly with a valuable resource nearly every farmer wants more of during planting season: time.

The southwest Minnesota farmer says he is able to create a good seedbed while leaving residue between rows for erosion control and moisture conservation. The result is a significant head start on every season.

“I build strips in the fall, and then I plant right into those strips in the spring,” he says. “While [conventional till farmers] are trying to figure out which field they can go hit with the field cultivator, I’m already out setting my planter.”

Verly’s experience reflects a key benefit: using strip-till can reduce field time by nearly 50%, according to the Strip-Till Farmer 2025 Operational Benchmark Study.

Efficiency in Fuel and Horsepower

Five years ago, Verly was looking for a way to transition away from conventional tillage. The move to strip-till allowed him to reduce his high-horsepower needs and fuel consumption.

“With conventional till, we run a 500 QuadTrac, which can burn over 25 gallons of fuel per hour, and I’ve eliminated a pass,” Verly explains. “I’m running a smaller tractor with my strip-till. There’s a lot of variables to doing strip-till, but if you add them all together, there’s savings to be had.”

Beyond time and fuel, strip-tillage allows for better precision in nutrient management. Verly aligns his fertility program directly with the strip.

“My fertilizer is right where I’m putting my corn and soybean seed,” he says. This targeting helps him maximize every nutrient dollar spent on the ground his grandfather started farming more than 80 years ago.

Before making the switch to strip-till, Ken Ferrie advises farmers to balance pH levels since soil will no longer be mixed. “After you begin strip-tilling, you can then apply smaller lime applications more frequently,” notes Ferrie, Farm Journal Field Agronomist.

Navigating the Learning Curve

Transitioning to strip-till is a management shift that requires a flexible mindset. Garrett Asmus, a fifth-generation farmer from north-central Iowa, suggests that new adopters be prepared to deal more with residue.

“You’re not working the ground and hiding the residue, so there can be times when there’s a lot more of it on the surface to manage,” Asmus says. “Make sure your planter is equipped to handle it.”

Asmus also emphasizes the important role technology plays in the process: “GPS lines are very important with strip-till because you’re putting that narrow strip down (usually 6” to 10”), and then you have to come plant directly over that, so accuracy is really important.”

Verly agrees that “tinkering” is part of the process. “Every year is different. Some years it’s a breeze, and some years you’re out there struggling a little bit,” he says. “There’s a ton of adjustability on these machines, and you need to be willing to make adjustments for your conditions and for each season.”

Asmus, who farms with his dad, Harlan, says they started their journey to strip-till in 2002, working with an experienced custom operator who could teach them the ropes and minimize the potential for costly mistakes. They continued the arrangement for nearly a decade.

“At that point, we invested in our own strip-till bar, and went 100% strip-till,” Asmus recalls.

Timing and Resilience

While Verly and Asmus prefer to build strips in the fall, Ferrie notes that creating spring strips are an option, provided the weather cooperates.

“We’ve built strips in March and early April, and when we got rain to settle them we got a decent seedbed,” Ferrie says.

However, in dry years, he notes that spring-built strips can dry out too much — but there is a Plan B available. “If it’s too dry to plant in the strips, it’s usually dry enough to no-till,” he adds.

The Long-Term Payoff: Yield and Soil Health

Strip-till requires a “long game” strategy. Verly notes that the most valuable results can take a few seasons to achieve.

“You’re not going to see results the first year. You’re going to see results the third year, the fourth year, the fifth year,” he says.

For Verly, the proof is in the bin. Before the switch, he says his soybeans had hit a yield ceiling of 50 to 55 bushels. “By my fourth or fifth year with strip till, I was getting 70 to 72 bushels,” he says, adding he expects to see additional yield increases over time.

“Soil health equals plant health, plant health equals yield,” he says.

Is Strip-Till Right for You?

Ken Ferrie offers five questions for you to consider if you’re contemplating making a move to strip-till:

How well can you manage disease pressure?
Are you willing to take the time to adjust your planter for conditions in each field?
Can you control gully erosion in strips on rolling ground?
Can you control weeds with a burndown herbicide?
How will you manage traffic so you don’t drive over the strips with herbicide and fertilizer applications?

Smart Strategies for Topdressing Dry Fertilizer

If you’re topdressing corn acres this spring with dry fertilizer, keep in mind how that product is managed in a high-residue system will determine whether the fertilizer feeds your crop or disappears into thin air.

Ken Ferrie notes that farmers in his area, central Illinois, commonly use ammonium sulfate, urea and potash for topdressing. He says every hour untreated urea sits on the field surface is a chance for the nitrogen (N) in the fertilizer to gas off and disappear.

“The ammonium sulfate is stable, but the urea has potential to get away when it breaks down,” explains Ferrie, Farm Journal Field Agronomist.

That “getting away” is nitrogen loss caused through volatilization—when N escapes as ammonia gas instead of being captured in the soil as ammonium. In a corn-on-corn rotation, with a lot of stalks and leaves on the field surface for instance, the risk for volatilization is even higher.

Residue Can Supercharge Urease

The problem starts with a naturally occurring soil enzyme called urease. It’s what kicks off the breakdown of urea into ammonia and then ammonium. In a corn-on-corn field with lots of residue, the urease is supercharged.

“The thing about urease enzyme here in the surface with all this residue, it is 10 times higher than it would be in the soil,” he says.
The enzyme goes to work quickly, converting urea to ammonia at the soil–air interface, and that ammonia can simply drift off into the atmosphere. The more time it spends on the surface, the higher the odds of loss.

That’s why timing and management of dry fertilizer applications are critical.

“We sometimes say you need to keep the pin in the grenade – keep the urease enzyme at bay until we can get it worked in or rained in,” Ferrie says.

Evaluate Your Risk Potential

If tillage is in the plan, your solution to prevent volatilization is simple. Apply the fertilizer, then work it into the soil as soon as field conditions allow. When urea is incorporated, even lightly, any ammonia that forms is far more likely to be captured in the soil and converted to ammonium, where the crop can use it.

“There’s probably not a lot of worry in that scenario,” he says. “You’re going to incorporate this urea, and when it gasses, it’ll be in the soil, it’ll be captured.”

But not every system or scenario involves immediate tillage. In many no-till or strip-till fields, or when soil conditions are too wet for equipment, growers end up spreading fertilizer and then waiting on the weather to do the incorporation work. In those situations,
Ferrie warns, the risk of volatilization can increase quickly.

“If it’s going to lay out here and depend on rain [for incorporation], depending on how long that’s going to be, we’re going to need a urease inhibitor to give us time to get it rained in,” he says.

Urease inhibitors can temporarily slow or stop enzyme activity, giving farmers a bigger window before significant nitrogen loss occurs. For fields with a lot of residue, that extra time can make a big difference—especially when the forecast is uncertain.

Alongside conventional urea plus a urease inhibitor, Ferrie points to another option – using ESN, a polymer-coated, encapsulated urea.

“The ESN basically keeps the urea protected,” he says. “In that situation, if we lay it on the surface, you’re going to have about 60 days of protection. If you incorporate it, in our studies, [it] would show about 30 days of protection.”

ESN uses a physical coating to regulate how quickly water gets in and dissolves the urea. For growers who want extended protection or are looking to match nitrogen release more closely with crop uptake, that can be a useful tool. Still, Ferrie’s quick to point out that this isn’t a one-size-fits-all solution.

“It’s quite a bit more expensive,” he notes, underscoring the need to weigh costs against potential risks. For some high-yield, intensively managed corn-on-corn systems, the extra investment might pencil out. For others, a urease inhibitor on regular urea, combined with smart timing and placement, might be the more economical choice.

In addition, farmers need to think through when and how the urea in a fertilizer blend will get treated, Ferrie says If a urease inhibitor is added after everything is mixed together, you end up paying to “treat” nutrients that don’t actually need it.

“Treat the urea before you add the ammonium sulfate and the potash, or you’re going to end up treating all of the product, otherwise,” he cautions.

Unlocking New Farm Revenue: Bayer’s Newgold Targets The Biofuel Boom

Fri, 20 Feb 2026 20:36:47 GMT

At the intersection of low-carbon fuels and practical farm economics, Bayer’s newgold seed brand is being developed, offering an opportunity for farmers to make additional income from their existing acres.

By inserting high-oil, low-carbon intensity crops such as camelina and canola into idle/fallow acres or wheat rotations, growers can tap into a new income stream that feeds the fast-growing biomass-based diesel market.

The new opportunities are backed by defined grain contracts, downstream demand, and long-term R&D investment, according to Chad Bilby, Bayer biofuel crops innovation and commercial lead.

Bilby says Bayer’s biofuel crops portfolio is currently centered on three crops:

1. Camelina (spring and winter): Under the newgold brand, initial focus for 2026 is in the northern Great Plains (southern Saskatchewan, southeast Alberta, eastern Montana, western North Dakota), with potential expansion as the program and value chain build out.

2. Winter canola: Also under newgold, the crop is targeted for commercial planting starting in September 2027 in the southern Great Plains (Kansas, Oklahoma, northern Texas) within wheat rotation systems.

3. CoverCress: This offering is a joint venture between Bayer, Chevron and Bunge and has been in place for several years. CoverCress is an oilseed targeted to corn-soybean farmers in the Midwest and used to produce low-carbon intensity oil for renewable fuels and high-protein meal for animal feed.

“All these crops that we’re focused on are geared for the biomass-based diesel segment of biofuels,” Bilby says. “When you look at biodiesel, renewable diesel, sustainable aviation fuel… a lot of the higher horsepower engines where electric vehicles are not going to play a role are really seeking a path to get access to biofuels,” he adds.

Seed to Market: Closed-Loop System and Value-Chain Alignment

Newgold is being built on the recognition by Bayer that agronomy alone doesn’t make a new crop successful for farmers — marketing certainty is needed.

Because many specialty oilseeds, such as camelina, don’t have a standard commodity market behind them already, Bayer is structuring a closed-loop, contract-based system from the outset.

“Some of these crops aren’t a commodity trade, so something like camelina or CoverCress, you don’t have a market for those crops,” Bilby explains. “There will be a grain contract in place that will establish the pricing and delivery options… farmers will have that grain contract available. And then in the case of a camelina or winter canola, we will then sell the seed to the farmer against that contract to fulfill the contract.”

In parallel, Bayer is working across the entire value chain to align agronomy, grain flow and processing capacity.

“We’re collaborating closely with value chain partners,” Bilby says. “So as crush and renewable fuel capacity comes online, [farmers will] have a locally relevant crop and clear contracting options, kind of a seamless path from seed to market,” he says. “This is going to help ensure that agronomic fit, and that grain logistics and crush demand start to scale together.”

On the distribution side, newgold will tap into Bayer’s existing retail networks but says it won’t be locked into any single channel. Bilby notes that Bayer will leverage relationships and brands like DEKALB, WestBred, and others, but the newgold label gives the company the freedom to choose the best local partners.

More formal announcements around the Bayer newgold brand and opportunities are expected in the coming weeks. Farmers can learn more of the various program details by contacting their local Bayer representative.

Is Your Nitrogen Program Leaving Bushels and ROI Behind?

Thu, 19 Feb 2026 19:20:17 GMT

Corn gives farmers three big chances during the growing season to turn nitrogen (N) into higher yields — but most fertilizer programs only partially hit the key windows, according to University of Illinois crop physiologist Fred Below.

His team’s research indicates there are three critical periods — early growth, vegetative and grain fill — where precise timing and placement can drive yields higher with smarter use of the same amount of N.

Below says corn’s nitrogen supply is essentially a two-way partnership between the soil and fertilizer. About half of the N the crop uses comes from the soil as organic matter breaks down, and the other half comes from applied fertilizer. For 230-bushel corn, for example, the crop accumulates about 260 lb. N per acre over the season, with roughly 130 lb. coming from the soil and 130 lb. from fertilizer.

Here’s a summary of Below’s latest research on N timing and placement — and how you can put the findings to work in your fields this season.

1. Early Growth: Small Uptake, Huge Benefits

On paper, early-season N uptake looks modest. But Below warns that starving a corn crop early is a huge mistake with season-long consequences.

“The corn plant senses nitrogen availability from a very early age, and it sets yield potential based on that,” he says. “If you don’t have enough nitrogen at the beginning, you will not set [high] yield potential.”

That makes well-placed N at planting a powerful tool.

Below’s team compared banded N to broadcast N at planting, holding total N use at 180 lb. per acre and then varying upfront vs. sidedress ratios, across multiple Illinois sites and years. Three things the team determined:

* Banding or a 2x2 application at planting generally out-yielded broadcast across treatments, averaging about a 7-bushel advantage.

* With broadcast, the exact upfront-to-sidedress ratio was critical — farmers often needed more N upfront to protect yield.

* With banded N, the system was more forgiving: a smaller, well-placed band at planting could set yield potential, then sidedress could be timed to match peak uptake.

2. Vegetative Stages: The Make-or-Break Window For N Uptake

By flowering (R1), Below’s data show a 230-bushel crop has already taken up about 75% of its nitrogen — roughly 200 lb. N per acre.

“When the crop flowers, it’s got 75% of its nitrogen. That’s for the ear development and for the grain,” he says.

Using integrated uptake curves, Below’s research team calculated that during peak vegetative growth, corn can take up more than 7 lb. of N per acre per day.

“That is the most important period in nitrogen uptake by corn,” he says. “You cannot increase yield without increasing the peak uptake.”

If N isn’t readily available in the root zone when that peak demand hits, yield will drop — regardless of how much total N is applied.

The placement of N is critical, Below adds, because corn roots move predominantly down into the soil and not horizontally, as he notes in the photo below.

(Fred Below)

In field trials comparing sidedress N applied down the middle of the row versus along the row with a Y-drop, the results showed the latter performed best. This approach ensures an N “reservoir” is around the roots during this peak uptake period, supporting higher yields without necessarily increasing total fertilizer rates, Below adds.

3. Grain Fill: Finishing the Job

By late season, corn isn’t taking up much nitrogen through the roots. Only about a quarter of its total N comes after flowering. Instead, the plant mostly pulls nitrogen out of the leaves and stalks and sends it to the ear to fill kernels.

If the crop is nitrogen-deficient, it robs the leaves of N faster, causing the canopy to “burn down” prematurely. This reduces the plant’s ability to finish grain fill and build deep and heavy kernels.

Below stresses that any late-season N application is fine-tuning, not a rescue pass. If the crop is already showing nitrogen deficiency (firing), the yield penalty has already been paid. However, he adds, in healthy fields with good moisture, a modest late-N application can help keep leaves green longer and improve the finish on the ear and deliver ROI.

Below’s research on nitrogen use was funded by the Illinois Nutrient Research & Education Council (NREC).

Know The Rules For Dicamba Use In Your State

Wed, 18 Feb 2026 19:50:50 GMT

The EPA has finalized the dicamba label for the next two growing seasons, bringing much-needed clarity to U.S. farmers. But while over-the-top (OTT) use is officially back, it arrives with the most restrictive federal requirements farmers have seen to date for products like Engenia , Tavium , and Bayer’s new XtendiMax replacement, Stryax .

In some cases, states are adopting stronger regulations for dicamba use, especially with regard to temperature and calendar cutoffs:

Temperature Cutoff: The federal label mandates a 95°F forecast high as a hard cutoff. If the National Weather Service forecasts a high above 95°F, you cannot legally spray OTT dicamba that day.
No Federal Calendar Cutoff: Unlike previous labels, the EPA has not set a nationwide calendar deadline.

State-Specific Restrictions In Place

Illinois and Minnesota are two states, so far, that are going with stricter regulations for temperature and application timing cutoffs for dicamba.

Illinois is using an 85°F forecast high as the cutoff for dicamba applications in soybeans.

“If you load your sprayer and it is 78 degrees at 10 a.m. in the morning, but the forecasted high by the National Weather Service is supposed to be 85 or 86, that is a do-not-spray day,” says Kevin Johnson, director of government relations and strategy for the Illinois Soybean Association.

Deadline for application: Plan for a June 20 cutoff for OTT applications, Johnson says.

Minnesota:

Temperature: Minnesota is using an 85°F forecast high cutoff for dicamba applications in soybeans.

Deadline for applications: June 12 cutoff south of I-94; June 30 cutoff north of I-94, according to Dicamba Restrictions Announced for 2026 Growing Season .

Shifting Your Weed Control Strategy

Because of the tighter application timing windows in Illinois, Johnson anticipates there could be a shift in how farmers there use the chemistry. He expects many Illinois farmers to move dicamba to a pre-emergence timing rather than post-emergence, saving OTT dicamba only for “super high weed” pressure situations.

With many seed trait packages now stacking dicamba and glufosinate (Liberty) tolerance, Johnson says to expect “a lot more guys using Liberty on the back end.”

In addition, the EPA is tying dicamba use to mandatory conservation practices. Farmers can find more details on the Bulletins Live! Two Website

“We’re still waiting on a lot of details on what those conservation practices are,” Johnson says. “Bulletins Live! Two is a good website, but it’s, I’ll say clunky… it’s not real easy to just find one thing and find what you need,” he cautions.

Record Keeping: Don’t Risk A $700 Fine

The most immediate hurdle for many farmers interested in using the technology this spring will be the paperwork. In Illinois, the Department of Agriculture uses a 22-question record-keeping sheet specifically for dicamba.

“If I can stress anything in this call, do your record keeping,” Johnson emphasizes. “If you ever get called in on a complaint, the first thing they ask you for is your record keeping. If you do not have all 22 questions filled out, you are going to get a $700 fine. There’s no questions asked.”

To stay ahead of that risk, Johnson advises Illinois farmers to complete records on a timely basis, not “later when things slow down.” He urges them to fill out as much of the form as possible before the season begins, including static information about equipment, farm identifiers, and general practices, then finish the day-specific entries in the cab during or immediately after the job. Some of the information—like wind speed, wind direction, and exact application timing—can only be captured accurately in real time.

For custom applications, the legal burden for record keeping falls on the applicator, Johnson adds, but growers should still ask for copies for their own files and talk openly with retailers about documentation expectations.

All of this points toward one overarching need, Johnson says: have a clear herbicide game plan for 2026, especially if you plan to use dicamba, and build in contingencies. He addresses more of the dicamba requirements specific to Illinois farmers in a recent Field Advisor podcast, available here .

Seed Powerhouse Flexes Its Muscle With Sharpened Brands, Stronger Local Focus

Fri, 13 Feb 2026 22:30:27 GMT

GDM’s acquisition of AgReliant Genetics is moving from a finalized deal to a focused reality for U.S. growers. As the company asserts its place among the top-four corn and soybean seed providers in the country, it is redrawing its brand map to eliminate overlap and improve service.

In the process, Austin Horn, GDM spokesman and brand leader for Mustang Seeds, says the company is focused on providing more impactful, “boots-on-the-ground” support for farmers.

Here is a breakdown of the realignment and what it means for U.S. row-crop growers.

A New Brand Architecture

Horn says GDM’s new structure is anchored by five seed brands:

AgriGold: Serving Corn Belt states from Ohio to Nebraska.
Mustang Seeds: Serving the northern Corn Belt, including the Dakotas, Minnesota, and Wisconsin.
Producers Hybrids: Launching to strengthen the company’s presence in Texas and the West.
Donmario & Revere: These brands remain “business as usual,” Horn notes. Donmario continues its focus on soybeans, while Revere serves the Southeast, Delta, and Kentucky regions with corn, soybeans and wheat.

The Retirement of LG Seeds

As part of GDM’s realignment strategy, the LG Seeds brand will be retired and absorbed into the new structure.

Horn emphasizes that the heritage of LG Seeds’ products and service isn’t being discarded, that it’s being carried forward.

“While the name may be going away, its strength of seed products and service is not. It’s going to be continued on in the other brands that it’s being absorbed into,” he says.

Timeline: Expect Few Changes for 2026

Farmers planning for the 2026 season can expect minimal changes. The transition to the new brand strategy will not begin in earnest, Horn notes, until the industry turns its attention to 2027.

“For this year, the changes will be minimal,” he says. “There aren’t any changes that should take shape this year because of that. The current teams, the current brands, the current logos, the current seed hybrids and varieties none of that will change.”

Farmers can expect implementation of the new brand strategy to start only “after seed is in the ground,” he adds.

Strategic Rationale: Focus and Efficiency

One of the primary drivers for the reorganization, Horn says, is the elimination of overlapping footprints. By focusing on one primary brand per geography, the company intends to make its marketing and support dollars work harder.

“We’re removing the overlap so that when we spend $1 it goes to one brand in a more powerful way, versus fragmenting that dollar across multiple brands and having mixed messages,” Horn explains.

Despite some staff reductions due to the realignment and elimination of LG Seeds, Horn stresses that the long-term goal is to increase local support for farmers: “At the end of the day, we’re actually gaining more boots on the ground with our brands versus what each brand had before.”

A Seed-Only Focus In The Marketplace

As GDM rolls out its realignment strategy, the company has cemented its position as one of the top-five juggernauts in the U.S. corn and soybean seed industry, which also includes BASF, Bayer, Corteva and Syngenta.

Corteva and Bayer provided more than half the U.S. retail seed sales of corn, soybeans, and cotton in 2018–20, the most recent period for which estimates are available, according to a 2023 USDA Economic Research Service report .

Horn highlights GDM’s large global footprint—controlling roughly 45% of global soybean genetics—and its unique position as a company dedicated solely to seed.

“The others have focus on other parts of the ag input industry,” he points out, referencing their focus on crop protection products.

Horn contends GDM ranks at least fourth in the U.S. seed industry today — if not third — and has plans to move even higher in the lineup.

“We’ve got ambitions to be the largest and most impactful seed-focused breeding engine and product engine out there,” he says. “And I would argue that we are well on our way.”

In the process, Horn’s message to farmers is that they remain the center of the strategy, even as brands consolidate and market footprints are redrawn.

“This is all being done with our customers in mind,” he says. “We’ve heard from a lot of people already that they’re excited and ready to see the strategy play out.”

Two Ways 45Z Will Help Farmers Capture Dollars

Wed, 11 Feb 2026 16:24:33 GMT

For the past couple of years, the buzz around the 45Z tax credit has been little more than background noise at coffee shops and farmer meetings. But the “wait and see” period is over, according to University of Illinois Ag Economist Scott Irwin. As the policy takes root, it is fundamentally changing the ledgers of the ethanol plants you deliver to—and, by extension, could improve the profit potential for your farm.

According to Irwin, agriculture is in the process of entering a “mini ethanol boom.” After a decade of stagnant capacity, the industry is suddenly in growth mode.

“Three different ethanol plants have already announced expansions, and there will be more, all due to the 45Z tax credit,” Irwin reports.

The Section 45Z Clean Fuel Production Credit, often called the “Clean Fuel Credit,” is a federal tax incentive that rewards the production of low-carbon biofuels.

Doubling the Bottom Line

To understand why your local ethanol plant might suddenly be eyeing an expansion, you have to look at their margins. Since 2007,
Irwin has tracked the profitability of the typical Midwest dry-mill plant, finding that most have a profit of about 12 cents per gallon.

That profit margin goes up a lot with the adoption of 45Z. Irwin estimates that even a “plain vanilla” plant—one that hasn’t invested a dime in carbon capture—will qualify for roughly 11 cents per gallon in credits.

“Their margin has been 12 cents, and all of a sudden the U.S. government is helicoptering in an additional 10–11 cents, essentially doubling their income,” Irwin says.

For the plants playing the long game with carbon capture and storage (CCS), the profit potential moves from good to an astounding number.

“A 200-million-gallon dry mill ethanol plant that can inject its CO₂… I estimate that they’ll probably get a credit of 60 cents a gallon,” Irwin says. “That means a 200-million-gallon plant will earn $120 million of credits a year over the four years that this is on the books for. It’s almost half a billion dollars.”

With that kind of profit potential, plants won’t just be staying open; they’ll be hungry for grain. “I think we are going to see every plant running flat out with those kind of dollars in front of them,” Irwin notes.

How the Dollars Can Reach Your Farm

While the 45Z credit will be paid directly to the processors, the ripple effect will find its way into your bank account through two primary channels: local basis and premiums.

1. A Stronger Local Basis: As plants “run flat out” to maximize their credits, their demand for physical bushels will tighten the local market.

“For those farmers that are in the ‘draw territory’ for ethanol plants, they’ll probably see a bit stronger local basis, five cents or so,” Irwin anticipates.

2. The Low-CI Premium: The bigger opportunity, however, lies in helping reduce a plant’s Carbon Intensity (CI) score. By using climate-smart practices like no-till, strip-till, or in-season nitrogen use to grow crops, you can help lower the plant’s overall CI score—which makes their 45Z credit even more valuable.

“For each point that the ethanol plant’s carbon intensity score is reduced, the plant will earn about two cents per gallon of ethanol produced,” Irwin says. “I’ve heard that it might be up to 10 points, which would be 20 cents. That’s significant.”

Forward-thinking plants are already evaluating ways to partner with farmers — and share their windfall — who will make a lower CI score possible.

“I have talked to ethanol plants that have really thought this through and are ready to work with their farmer customers on a sharing agreement for the farmers’ role in reducing the ethanol plant’s CI,” Irwin says.

He advises farmers interested in working with their local ethanol plant to reach out to them and start a conversation. Three things to discuss:

Ask if they plan to claim 45Z credits and what their timeline looks like.
Find out if they are building a formal low-CI or climate-smart sourcing program.
Ask which practices (no-till, split N, etc.) and what documentation the plant will require.

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 .

A High-ROI Strategy for Corn Planter Upgrades and Stand Success

Fri, 06 Feb 2026 19:24:00 GMT

During a recent Farm Journal Corn College session, Field Agronomist Ken Ferrie tackled some of the tough questions growers have about closing systems and stand evaluation. From why social media trends shouldn’t dictate your equipment budget to the “ground-truthing” techniques that reveal hidden planting errors, Ferrie breaks down how to ensure your planter setup delivers a true return on investment this spring. Here are three questions Ferrie answered in detail:

1. Question: “Where would you rank the value of updating the closing wheel system compared to other planter attachments?”

Answer: Ferrie says before ranking anything, you need to know what problem you’re trying to solve. Today, you can easily spend as much on planter attachments as you did on the planter itself. So, every attachment needs a clear purpose and a clear return.
Whenever a farmer asks him about new attachments, Ferrie always asks a question of his own: “What do you hope this investment will do for you?”

“Too often, the honest reply is, ‘I don’t know, but I saw it on social media or at a farm show and it looked interesting,’” Ferrie notes.

He explains if you’re routinely evaluating corn stands and can see that your current closing system is not doing the job — there’s poor trench closure, sidewall smearing issues, uneven emergence — then upgrading that system can offer a strong ROI. But if your real limiting factor is row-unit downforce, leading to uneven depth and sidewall smearing, then changing the closing wheels won’t move the needle like fixing the downforce will.

Ferrie says if he had to pick “the top advancement” for corn stand establishment, it would be hydraulic downforce systems that both push and lift, and adjust on the go.

“Those systems, both in conventional and no-till situations, have done a lot to improve stands by maintaining consistent depth and reducing sidewall problems,” he says.

2. Question: “How can I evaluate my stand to identify if my closing system is an issue?”

Answer: Ferrie says good stand evaluation doesn’t start weeks after crop emergence. Instead, it starts at the planter.

“Ground-truthing your planter performance at planting can prevent a lot of stand issues later on,” Ferrie says. “This practice needs to be done on multiple rows across the planter, and in multiple soil types within the field.”

Ferrie’s recommendation: stop the planter several times in each field, get out and dig a cross-section across the furrow. In that crosscut, you’re looking for several problems that might need to be corrected.

(Crop-Tech Consulting)

A “perfect” cross-section, Ferrie says, is one where there’s no evidence of sidewalls standing, and no dry soil or air pockets are surrounding the seed.

He also reminds growers that the first 12 hours after planting, when the seed imbibes water, are critical. Dry soil around the seed in that window of time will delay water uptake and slow emergence.

Once the corn crop is out of the ground, shift your evaluation process to stand uniformity. At this point, Ferrie recommends doing plant counts and writing your observations down for future reference.

“Pay special attention to plants that are more than one collar behind their neighbors,” he says. “Those lagging plants should be dug up and examined.”

(Crop-Tech Consulting)

3. Question: “Can you put too much downforce on cast iron closing wheels?”

Answer: Yes, you definitely can, particularly in tilled or strip-tilled fields. Ferrie explains that excessive downforce on cast iron wheels can cause unnecessary compaction that young plants must fight through. The wheels can cut a deep trench in the furrow and push soil up into a ridge between the wheels.

This can create emergence problems in a couple of ways. If the spike doesn’t emerge dead center of the furrow, it may come up early off to the side, or it may attempt to leaf out underground if enough light filters down into the trench.

For plants that do emerge dead center, there’s another risk. As they break through that crown of soil pushed up by the closing wheels, they tend to set their crown roots about three-quarters of an inch below that raised ridge, Ferrie notes. If a heavy rain comes after emergence and flattens that ridge, those plants are effectively left with shallow crown roots — shallow corn that is more vulnerable to stress.
