‘We Need Rain’: Dry Fields Stall Corn Planting

Wed, 13 May 2026 21:40:40 GMT

Planting season sounds different across central Kansas this year. By mid-May, planters usually run full tilt, pushing long days and short nights as growers race to get corn, soybeans, and grain sorghum into the ground. Instead, silence hangs over many fields. Drought-stressed soils, soaring fertilizer costs, and mounting economic pressures have kept many farmers from even starting, according to Matt Splitter.

“We’ve had 1.2 to 1.5 inches of rain this year during a window where we should be at 28 inches,” says Splitter, who farms in the I-35 corridor between Kansas City and Wichita. “It is dry. I can’t even find the right words for how dry it is.”

The data backs up his frustration. Approximately 65% of topsoil moisture in Kansas is currently rated as “short” or “very short,” according to the May 11 Crop Progress & Condition Report.

On a recent school run, Splitter looked across empty fields that would typically be full of machinery.

“I took the kids to school and didn’t see one machine in a field — no tillage, no applications, no planting,” he told Chip Flory, host of AgriTalk. “Planting progress here is non-existent.”

Personally, Splitter gambled early on planting his corn, hoping the scant moisture near the soil surface would be enough to get a stand.

“We went early, thinking we were probably making the wrong decision,” he says. “We had just enough moisture for germination. The corn is up, but it can’t hang in there much longer.”

The National Picture

Corn planting in central Kansas, other parts of the High Plains and in the Southeast has been slow-going this spring. However, some states are surging ahead. Nationwide, 57% of the 2026 corn crop is in the ground, outpacing the five-year average of 52%.

The Crop Progress Report indicates the national average is being buoyed by high-efficiency corn planting in parts of the mid-South and Midwest:

The Early Birds: Tennessee and Kentucky are nearly finished, reporting 92% and 87% completion.
Midwest States: Iowa leads the I-states at 72% planted, while Illinois sits at 54%. Minnesota is at nearly 70% completion.
Emergence: Nationally, 23% of the crop has emerged — trailing last year’s 26% due to cooler, drier soils across the Central Plains.

Farming From A Desk in Kentucky

In central Kentucky, millennial farmer Quint Pottinger is planting corn from behind a desk, watching his fully autonomous tractor crawl across his fields, thanks to a computer screen. Pottinger says technology is his primary weapon against the brutal economic environment U.S. farmers are dealing with.

High expenses led him to equip a 100‑hp tractor with a Sabanto retrofit kit, sell his big-frame 8,000‑series tractors and 40‑foot planters, and move to a smaller 20‑foot planter. The result: he’s running a lot slower, but cheaper.

“We sold two large tractors, two big planters. That was the only way we knew how to cut costs in this economic environment we’re in, and we had no idea if it would work,” Pottinger says.

The trade-off is speed, but the gain is efficiency. “I can slow this planter down to 2.5 miles an hour to get the right depth as the soil dries out,” he adds.

Despite a smoother start than the flood-plagued springs of the last two years, weather remains a hurdle. A sudden frost during pollination “dinged” his wheat crop, causing a 20% loss in some areas.

The one bright spot? His rye grown for the whiskey industry is looking good. “It just grinds through this weather and keeps going. It’s a whole different animal,” Pottinger says.

The Fertilizer Squeeze

For both farmers, the drought collides with a second crisis: fertilizer prices. In Kansas, Splitter is trimming his nitrogen rates by 25% to 30%.

“We’re so dry that even if you apply fertilizer, the risk of volatilization is just too high,” Splitter explains. “We’re not spending as much money, because it wouldn’t do any good anyway. But there’s no truly ‘good’ decision here — it’s a perfect storm of bad options.”

In Kentucky, Pottinger’s attempt to lock in prices failed when global political shocks in the Strait of Hormuz voided his deferred pricing contracts. He was forced to buy at market price — when he could find supply at all. He worries the fallout will last years, especially if natural gas production for nitrogen doesn’t fully recover.

“This should be a problem for 2027, not 2026,” Pottinger says. “I fear farmers will get taken advantage of in both seasons, potentially stretching into 2028.”

Searching For Optimism

Despite the stalled planters and market anxiety, both men are looking for reasons to stay positive — be it through cost-saving technology or policy shifts like higher ethanol blends that could drive demand.

“In tough times like this, everybody’s trying to find something to be optimistic about,” Splitter says. “We should be that way as an industry as a whole. We shouldn’t be pitting one guy against the other. That’s not what American agriculture is about.”

For now, optimism for Splitter and Pottinger depends on a simple, old‑fashioned variable neither farmer can control.

“We need rain,” Pottinger says. “We need rain now.”

Rethink Your Herbicide Strategy In High-Residue Systems

Wed, 13 May 2026 17:24:08 GMT

Waterhemp and other tough weeds are forcing farmers to rethink how they use herbicides in high-residue cropping systems, from heavy corn stalks to thick cereal rye covers.

Extension weed scientists say they increasingly hear from growers who did “everything right” with applying their preemergence products yet still see waterhemp push through and survive. Increasingly, one of the challenges is those fields carry a lot more residue than they used to.

“Every year, we have some situations where we get less than expected control of weeds for various reasons, and I’ve come around to appreciate the impact that residue can have on our success,” says Tom Peters, Extension agronomist and weed control specialist for North Dakota State University and the University of Minnesota.

Oftentimes, the assumption has been that rainfall will wash herbicides off the residue and down into the soil, where they can do their job. Peters says that belief does not hold up in reality.

“I would argue that some of our performance challenges have been related to those herbicides sticking to the residues,” contends Peters, who made his comments during the 2026 Field Notes program.

That problem is on the increase as farmers are dialing back their tillage passes, planting into more corn and soybean residue and seeding more cover crops.

Reduction In Control Assessed

During graduate work with the University of Minnesota, Eric Yu, now a regional crops Extension educator, measured just how much product residue can intercept herbicides. In cover crop plots, he and his colleagues placed water-sensitive cards below cereal rye crops, applied a preemergence herbicide and then evaluated the results.

“We were seeing about a 50% reduction in the amount of product that reaches the soil compared to our control plots,” Yu says. “Yet despite that 50% reduction, we were seeing still significant weed control, specifically waterhemp control.”

The message, Yu says, is not that residue makes the use of pre products pointless. It is that farmers need to account for residue when they design their weed-control programs — and still keep a strong preemergence herbicide in the plan.

Peters agrees. Even when residue cuts the amount of product reaching the soil, pres are still the foundation of a good program, especially as waterhemp increases in resistance to postemergence herbicides.

“Start the season with pre products, observe your results and then decide what the best postemergence program is,” he advises.

For farmers managing crops in high-residue systems, Peters and Yu point to several practical steps:

Prioritize Soil Contact: Ensure herbicides are actually reaching the soil surface. In cases of extreme residue, it may be necessary to manage or move stalks and straw ahead of planting.
Adjust Product and Rate: Work with agronomists to select products and rates that can withstand some interception while still delivering enough active ingredient to the soil to be effective. Using full labeled rates is increasingly a best-practice solution for control and to reduce selection pressure for further herbicide resistance.
Tighten the Timing Window: Because residue can blunt the effectiveness of a pre product, escapes are more likely. Small waterhemp is much easier to control; once the weed reaches the 4- to 5-inch range, control becomes significantly more difficult.

Researchers Evaluate 21 Herbicides

A group of University of Wisconsin-Madison scientists recently studied which herbicides make it to the ground and provide residual waterhemp control in high-residue farming systems. The controlled-environment study evaluated 21 single-active-ingredient corn and/or soybean herbicides compatible with high-biomass cereal rye. Here are the results, courtesy of GROW :

Corn herbicides identified as effective for waterhemp control and compatible with high-biomass cereal rye in this study included:

Acetochlor (Harness – Group 15)
Dimethenamid-P (Outlook – Group 15)
Pyroxasulfone (Zidua – Group 15)
S-metolachlor (Dual II Magnum – Group 15)
Atrazine (Group 5)*
Isoxaflutole (Balance Flexx – Group 27)
Mesotrione (Callisto – Group 27)

*waterhemp population used in this study is still susceptible to atrazine applied preemergence.

Soybean herbicides identified as effective for waterhemp control and compatible with high-biomass cereal rye in this study included:

Dimethenamid-P (Outlook – Group 15)
Pyroxasulfone (Zidua – Group 15)
S-metolachlor (Dual II Magnum – Group 15)
Flumioxazin (Valor – Group 14)
Fomesafen (Flexstar – Group 14)
Metribuzin (Group 5)

The Wisconsin researchers say soybean growers should pay close attention to application timing restrictions. Flumioxazin-containing products for instance must be applied within three days of soybean planting, while metribuzin must be applied prior to soybean emergence. The remaining soybean herbicides listed above can be applied preemergence or early postemergence, offering flexibility for growers who plant early and delay cereal rye termination until after soybean emergence.

A standard program in planting green systems where the cereal rye is terminated after soybean emergence may include glyphosate for cereal rye termination, combined with soil residual herbicides fomesafen plus a Group 15 herbicide (e.g., pyroxasulfone, S-metolachlor, or dimethenamid-P) and a Group 2 herbicide such as imazethapyr (Pursuit), cloransulam (FirstRate), or chlorimuron (Classic) for broad spectrum weed control.

Corteva Launches New Fungicide For Sugarbeets

Wed, 13 May 2026 13:30:39 GMT

Corteva Agriscience announced Wednesday the U.S. launch of Verpixo fungicide, a new tool designed to combat Cercospora leaf spot (CLS) in sugarbeets.

The U.S. Environmental Protection Agency has registered the product for the 2026 growing season. Verpixo features Adavelt active, which the EPA has designated as a reduced-risk chemistry.

New Mode of Action

Verpixo introduces a Fungicide Resistance Action Committee (FRAC) Group 21 mode of action to the sugarbeet market. Derived from a naturally occurring compound in soil bacteria, the fungicide offers broad-spectrum control and provides growers with increased application flexibility.

Cercospora leaf spot is considered the most economically damaging fungal disease for the U.S. sugarbeet industry. According to the Beet Sugar Development Foundation, the disease could have caused more than $900 million in economic losses during the 2024 production year if left unmanaged.

“Extensive lab and in-field testing confirm the efficacy of Verpixo fungicide with Adavelt active against CLS, which can cause up to 30% annual yield loss,” says Colleen Kent, specialty crops portfolio marketing lead with Corteva, in a press release.

Combating Resistance

The disease is characterized by brown spots on leaves that inhibit a plant’s ability to photosynthesize, directly reducing sugar content and root weight. Because CLS is polycyclic—meaning it can produce spores multiple times in a single season—ongoing management is required.

Current fungicides and some genetic traits have seen a decline in efficacy due to resistance. Verpixo uses translaminar movement to protect both the top and bottom of leaf surfaces.

“Verpixo fungicide with Adavelt active has no known resistance, making it ideally suited for resistance management programs,” Kent reports.

Environmental Impact

Corteva stated that the product’s natural origin and environmental profile are compatible with Integrated Pest Management (IPM) programs, allowing beneficial insects to thrive while controlling the fungal pathogen.

The fungicide is now available for use in the 2026 season and is compatible with standard tank-mix practices.

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.”

Soybean Gall Midge Emerges As Top-Tier Threat

Mon, 11 May 2026 20:19:03 GMT

Soybean gall midge is no longer just a curiosity or annoyance for many Midwest farmers. The pest is chewing into yield and profitability for soybean growers across parts of at least seven states – Kansas, Iowa, Minnesota, Missouri, Nebraska, North Dakota, South Dakota.

Iowa State University Entomologist Erin Hodgson reports the pest’s footprint is significant, present in at least 42% of the 45.4 million acres of soybeans farmers harvested across the seven states in 2025.

“At least 19 million soybean acres are potentially impacted by this pest,” Hodgson says, noting that the pest continues to spread. Eight new counties were confirmed in 2025, with five of those being in Iowa .

According to a recent farmer survey led by University of Nebraska Entomologist Doug Golick, the pest has become a major threat in parts of Nebraska. “In the last year or two, soybean gall midge is approaching as near high of concern as herbicide-resistant weeds for survey respondents,” Golick says.

Since 2018, the soybean gall midge has spread to 185 total counties in seven states, including five new counties in Iowa this past year, according to Erin Hodgson, Iowa State University Extension entomologist and professor.

Look For Small Orange Or White Larvae

Damage from the insect starts at the base of the soybean plants, largely out of sight. Adult midges emerge from the ground in May and June, then seek out tiny fissures in young soybean plants near the soil line to lay eggs, according to Thales Rodrigues da Silva, a master’s student at the University of Nebraska–Lincoln.

The larvae cause severe, localized yield losses from 20% to 100% loss along field edges and 17% to 50% reductions in entire fields average under heavy infestation, according to University of Nebraska-Lincoln (UNL) Extension. The larvae – small, orange worm-like pests – feed inside the base of the stem, causing plants to wither, die, and lodge (break), with damages sometimes extending 100+ feet into fields. Scouting for the pest should occur after the second trifoliate (V2) growth stage, according to the Crop Protection Network.

This damage in a soybean plant at the soil level shows the result of soybean gall midge larvae feeding.

(University of Nebraska-Lincoln Extension)

Because the pest often feeds along field edges, the damage in affected plants is often mistaken for issues caused by compaction or herbicide injury, according to Stine Seed Company .

To confirm the pest’s presence, Stine agronomists recommend digging up compromised soybean plants and splitting open the stem. If white or orange larvae are found feeding within the inner layers, growers should check the Soybean Gall Midge Alert Network tracking system to determine whether the pest has been reported in their area. Next, they should contact their local Extension specialist to help confirm the diagnosis and report the finding if their county is not yet documented in their area.

Cultural Practices Show Promise

Unfortunately, there are few strategies to manage and control soybean gall midge, according to Tony Lenz, Stine technical agronomist.
With no labeled, consistently effective in-season insecticide program and no established treatment threshold, researchers are testing cultural and mechanical tactics that might give farmers at least partial relief.

Tillage ahead of planting — a tough sell in no-till systems — shows some promise in reducing early infestations in current-year soybean fields.

“Turns out that disking alone, at least in (our) study… did reduce infestation,” says Justin McMechan an entomologist and associate professor at UNL.

“There’s a significant reduction as we move from no-till to that… where it’s just disked and planted into, and then disking and hilling (a practice used in growing potatoes), which really is effective, because you’re covering up the infestation site,” McMechan adds.

He notes that even subtle changes in seedbed shape may help by covering fissures or altering microclimates at the stem base.

On planters running row cleaners, McMechan says adjustments at field edges might be one of the more accessible tools.

“There are not huge differences, but they are statistically significant,” he adds.

Field edge management has been another area of experimentation, including mowing or managing dense vegetation next to infested fields. Results are mixed, but McMechan says there are situations where mowing modestly cuts pressure.

“Nebraska saw on occasion where mowing would reduce infestation and lead to marginal yield benefit… we’re talking like 6-bushel differences,” he says, adding that weather and nearby corn canopy can override those gains.

There are no insecticides currently available to control soybean gall midge. A combination of cultural practices and mechanical efforts is likely the best option, for now, to stop or slow the pest.

Scientists Evaluate ‘Out-Of-The-Box’ Practices

Other work by researchers is pushing even further outside the box to find control measures. At UNL, graduate research assistant Kristin Heinrichs Stark is testing whether a biodegradable surface barrier called BioWrap can physically trap larvae in the soil and prevent emergence.

The work is early-stage and raises reasonable questions about cost and field-scale application rates, but it points to the kind of layered, non-chemical tactics Extension researchers say will likely be needed to address the pest.

Even as these cultural and physical strategies are developed, Hodgson reminds farmers that the ag industry still lacks any clear control option once larvae are inside the soybean stem.

“We really don’t have a treatment threshold, or a rescue treatment option at this time,” she says. “We know that the soybean gall midge certainly can cause yield losses, plant death, and that directly relates to yield. But we don’t really have great answers on like, how many plants does it take? How many larvae per plant (causes yield loss)?”

For now, farmers dealing with soybean gall midge are being asked to combine careful field scouting, crop rotation, and targeted cultural tactics to address the pest as the research community races to find answers and close those gaps.

Specialists from three Midwest universities provided the latest updates on soybean gall midge (SGM) this spring in a webinar, available at the link below:

Are Your Fields A Green Light? Use the Three-Factor System To Guide Planting Decisions

Fri, 08 May 2026 16:51:42 GMT

Farm Journal Field Agronomist Ken Ferrie is urging farmers to pay close attention to soil conditions and local weather forecasts as planting accelerates across the Midwest.

Ferrie and his team at Crop-Tech Consulting recommend using a “red-yellow-green light” system to guide planting decisions. The practice is based on three factors: soil moisture, seed chilling risks and the 10-day emergence forecast.

The information on the green-yellow-red color system for planting is pretty self-explanatory, says Ken Ferrie. Once you know the light color, you can see the meaning and the action he recommends taking.

(Crop-Tech Consulting)

Regional Forecast And Recommendation

Despite ongoing weather struggles from cold and rain in some parts of the country, planting progress continues across much of the upper Midwest.

For central Illinois, Ferrie says there is a green light for Monday, with some areas getting a yellow or red light for Tuesday. The U.S. National Weather Service says a weak cold front will bring the next chance for storms later on Tuesday, some of which could be severe. Temperatures will turn cooler for midweek.

Ferrie warns that the first 12 to 24 hours seed corn is in the ground are the most critical. During this window of time, the seed absorbs 30% of its weight in water. If that water is below 50 degrees Fahrenheit, the cells lose elasticity and tear. Chilled seed corn can easily result in a 10% stand loss.

“You can literally tell the difference between fields that were planted in the morning compared to in an afternoon that’s going into a cool night,” Ferrie says. “That is why you’ll see our lights change at noon some days, trying to get enough water absorbed before the soil temperature drops.”

You can get more information from Ferrie on the perils of seed corn chilling in this brief video:

Ferrie says if corn takes longer than 11 days to emerge, those kernels that were planted “spike down” will struggle to compete.

“The spike-down plants can be a week or two weeks behind the spike-up plants,” Ferrie explains. “At that point, they will be more than a collar behind and not produce a regular-sized ear.”

Oregon Farmers Navigate The Ups And Downs Of A Changing Ag Landscape

Wed, 06 May 2026 22:05:35 GMT

Helle and Bruce Ruddenklau make almost every agronomic move on their Willamette Valley, Oregon, farm with their balance sheet in mind. Crop rotations, contracts and niche markets are the core tools they use to maneuver through and survive today’s costly inputs and soft crop prices.

The couple farm about 1,100 acres near Amity, Ore. They own a third of the ground and rent the rest.

About half the acres are in commercial grass seed — perennial ryegrass and fescue for lawns, golf courses, sports fields and parks. The rest of their acreage cycles through wheat, an oilseed called Meadowfoam (highly sought after in cosmetics, skincare products, and specialty industrial applications), green beans, occasional sweet corn and peas, radish seed for export to Japan, clover seed and hazelnuts.

The crop diversity is critical. It helps even out the economic ups and downs of farming, and it also helps address a problem the couple didn’t even know they had initially in the 1990s: herbicide-resistant grass weeds, a challenge exacerbated by the fact they produce commercial grass seed.

“We had to come up with a different way of fighting some of these grassy weeds without chemistry, and that was through rotation. And no-till was the other big, big thing,” Helle recalls.

In the late 1990s, the couple invested in a no-till drill and redesigned their rotation.

“The (commercial) grass seeds stay in for two to four years, and when they come out, we have at least two years of other crops in those fields so we can get new chemical applications on, try to rotate and get on top of any grassy weeds that may have built up,” Helle tells Andrew McCrea during a recent episode of Farming The Countryside , available on Farm Journal TV.

Focused On Crop Diversity To Create Income

Crop rotation is a framework for stacking income streams. Every crop has to pull its weight against rising fertilizer and fuel costs.

“As with all farmers, our input costs are higher than what they have been. That’s been a huge challenge. Everybody here’s trying to find something that’s more profitable to grow,” she says, adding that she believes Midwest farmers have an even harder time generating ROI.

Grass seed has delivered strong margins at times, but COVID-era demand whipsawed the market. A surge in lawn and turf projects sent prices sharply higher in 2020. Seed companies then pushed acres. A couple of variable years later, and the industry became awash in seed.

“We’re still working through that oversupply from three years ago or so,” Helle says. “Our price has dropped in half, basically, from what it was.”

With prices cut and input costs elevated, some growers are rolling the dice and producing grass seed on speculation.

“You have the option to grow grass seed without a contract, and then you have it on the open market,” she says. “If there’s a market for it, you can sell it. If not, you just sit with [it] in the barn and wait.”

The Ruddenklaus work hard to avoid being in that position, growing most everything under contract.

“We have one field that we have an open market Kentucky 31 variety on. But other than that, everything we grow is under contract on both the grass seed, specialty crops, hazelnuts, vegetables, everything.”

Relationships Play An Important Role In Farming

That contract-first mindset shapes what they plant and who they do business with.

“A lot of it is relationships with different dealers… that we know they will treat us fairly, and they know that we will produce a quality product for them,” she says.

Those relationships open doors to new niche markets that fit within their existing rotation.

“A few years ago, a local economic development company came to us and said a local soy sauce manufacturer was looking to have some local production of hard red spring wheat,” she recalls. “Oregon traditionally grows soft white wheat, so it’s not something we had worked with in the past, but we decided to try it, and that’s become a very valuable little niche market for us that has worked out well.”

Through that same connection, the farm links with AgLaunch, a Tennessee-based network that brings farmers and ag tech startups together.

“The companies come in [and] want to get the support of the farmers, the advice, the on-farm trials,” she says. “In exchange, they have to give up some equity to the farmers’ network. So through that, we also are getting exposure to some new companies and potentially new opportunities. We are definitely always looking at things.”

Some experiments — like trying grain corn and soybeans — have not become permanent fixtures on the farm. But even those tests help the Ruddenklaus calibrate where their competitive edge really lies: in specialty crops backed by contracts and rotations that help them manage weeds and other risks at the same time.

“I think agriculture has an amazing, amazing story. Farmers are innovators, and that’s just part of what we have done through generations,” Helle says.

“I’m not pessimistic about where we’re at,” she adds. “I believe agriculture has a bright, bright future. We belong in society. We have an important role to play. It won’t look the same as it has in the past, but we’ll figure it out.”

Metabolic Weed Resistance Crisis Builds Across The Heartland

Wed, 06 May 2026 16:50:37 GMT

Waterhemp, Palmer amaranth and some other tough broadleaf weeds and grasses are no longer slipping past just single herbicides. Across the Corn Belt and beyond, they are tolerating entire herbicide programs. Weed scientists say that pattern points to a critical issue more farmers are facing: metabolic resistance.

Unlike traditional target-site resistance, which is often specific to a single herbicide class, metabolic resistance is even worse because it can confer cross-resistance to multiple, unrelated herbicide groups .

Aaron Hager, University of Illinois Extension weed scientist often warns that when a tough weed like waterhemp learns to metabolize one herbicide, it becomes easier for it to “learn” to detoxify others. That ability has helped lead to the 7-way resistance with waterhemp seen in some Illinois counties, according to weed scientist Patrick Tranel, one of Hager’s colleagues.

At least 13 states have reported having some degree of “highly suspected” or confirmed cases of metabolic weed resistance. Here are three of the broadleaf weeds demonstrating metabolic resistance and states where they’re located:

Along with these broadleaf weeds, some common and giant ragweed, marestail/horseweed, annual (Italian) ryegrass and barnyardgrass populations have also demonstrated metabolic resistance.

(Weed Science Society of America, GROW, BASF, Syngenta)

Target-site resistance can be identified through DNA tests. But metabolic resistance is a “guessing game” involving potentially dozens to hundreds of genes working in tandem, making it difficult for scientists and farmers to know which products will still work in their specific fields.

Tommy Butts sees the trend for metabolic resistance taking root in Indiana. He says HPPD resistance in waterhemp is “getting widespread,” and the failures are expanding to other chemistries as well.

“We had more complaints last year about things like mesotrione or Callisto starting to fail, which is really scary in the corn acres,” says Butts, Purdue University Extension weed scientist. “Corn is supposed to be our easy year to control waterhemp, and now, all of a sudden, we start losing Callisto.” He addresses this in detail in the latest Purdue Crop Chat .

The bad news does not stop there.

“You start talking auxins and glufosinate, and we have confirmed resistance in the state to those,” he says. “I wouldn’t say that’s as widespread, but it’s definitely popping up.”

With metabolic resistance chipping away at PPOs, HPPDs, atrazine partners, auxins and glufosinate, the old playbook of “just switch products” no longer works well.

Glufosinate alone 😀⁰Mesotrione alone 😕⁰Glufosinate + mesotrione 🔥😎

That’s the power of effective herbicide tank mixtures.

“Hammer With Residuals” And Build Effective Combinations

Butts’ first message to corn and soybean farmers is straightforward: no more solo herbicide passes in the field.

“We have to hammer weeds with effective residuals and then mix up our posts as much as possible,” he says.

In his view, that means at least two things for row-crop growers. First, use layered residual programs that keep fields clean as long as possible and reduce the number of emerged weeds that ever see a post pass. Second, use post-emerge applications that combine multiple, truly effective modes of action at full labeled rates.

Cutting rates, he warns, is exactly how growers “train” metabolism-based resistance to take root.

With soybean trait systems, he pushes hard against relying on a single flagship product.

“If we’re growing Enlist soybeans, don’t just rely on Enlist and don’t just rely on Liberty,” Butts advises. “Do the tank mix. The tank mix trumps everything.”

This field shows the result of waterhemp seeds that were spread during harvest by a combine.

Pay More Up Front To Avoid Making Expensive “Revenge Sprays”

Metabolic resistance can thrive when weeds are hit with chemistry they can partially tolerate. That is why Butts keeps coming back to strong, early, soil-applied programs.

He hears pushback from farmers every year on using multiple products in the tank.

“A lot of people tell me, ‘Well, it costs way too much up front with $20 for a pre. Corn gets even more expensive,’” he acknowledges.
However, Butts points to work by Purdue University Extension and other states showing those dollars pay off when the entire season is measured.

“If you can get a strong residual program out and get it activated, the whole-season economics of it makes sense,” Butts says. “It’s consistently shown that if you have that strong pre up front, you don’t have what I like to call the revenge sprays in August, where we’re going across the field three different times trying to kill waist-high waterhemp.”

Check out this tool from GROW on how to address waterhemp specifically.

Protect Herbicide Tools To Extend Their Use

As more herbicide modes of action come under pressure, Butts singles out metribuzin as an example of a product that still pulls its weight in soybeans.

“Metribuzin is a big one in soybeans, because we don’t have a lot of resistance to that,” he says.

“I will also put in the plug for AMS in general, across the board,” Butts says. “That always helps with some of those products… when we start getting later in the season, we get more stressed weeds. AMS even tends to help there.”

Butts does caution farmers that AMS is not allowed in dicamba tank mixes for XtendFlex soybeans.

Underlying all of it is a blunt warning about what happens if growers decide to skimp on their weed control efforts.

“If you let it go even one year, now you’ve made yourself a mess for the next five to 10 years,” he says. “You’ve got to try and stay on top of weeds as much as possible.”

5 Practical Recommendations To Address Metabolic Resistance

Because metabolic resistance is so unpredictable, weed scientists have shifted their advice away from “rotating chemicals” toward a “zero-threshold” approach to control. The following metabolic resistance management recommendations have been presented by Aaron Hager, University of Illinois Weed Scientist, and Beck’s agronomists:

1. The primary focus of metabolic resistance management should be on decreasing the weed seed bank. This means that weeds must be eliminated before they ever go to seed.

2. A robust residual herbicide program should be used, not because residuals represent a different herbicide family but because they eliminate weeds at the earliest growth stages – slashing contributions to the weed seed bank.

3. Physically cutting weeds out of the crop must be included in the management plan, because physical elimination of weed escapes further slashes contributions to the weed seed bank.

4. Post-herbicide programs should shift from calendar-based timing to scouting-based timing. Once weeds break through a pre-emerge residual program, they must be eliminated. Such early targeting further slashes contributions to the weed seed bank.

5. Mechanical techniques, field cultivators, etc., should be used where possible to further the cause of decreased seed production.

Build A High-Yield Powerhouse From The Bottom Up

Tue, 05 May 2026 17:40:08 GMT

The planter monitor in your tractor cab insists the seed corn is tucked away at a 2.5-inch planting depth, but Randy Dowdy says to question that placement. The high-yield row-crop grower explains there is often a difference between what the planter monitor says and what the soil shows — and the gap between the two can rob farmers of yield potential before the crop ever breaks the soil surface.

“You have to distinguish between the planting depth and what we call the germination depth. It’s a potential problem we talk about all the time with our farmers in Total Acre ,” says Dowdy of his agronomic business he co-owns with David Hula, world champion corn grower.

Iowa State Extension defines planting depth as the placement of the seed corn in the soil, while germination depth (emergence) is where the corn nodal roots will form, regardless of the planting depth.

The discrepancy that can occur between the planting depth and germination depth often happens at the moment the seed trench is closed or shortly thereafter. The planter might place the seed at 2.5 inches, but the closing system can shift seed upward — especially in dry, loose soils. As the dirt settles the seed can end up germinating at a significantly shallower depth than the grower intended.

“When we check seed placement in an open furrow, there’s no doubt about it, we were planting at 2.5 inches,” Dowdy notes in a recent video. But as he moves behind the machine to inspect the closed row, the reality changes. In Dowdy’s field demonstration, the shift is dramatic, showing the seed is now sitting much closer to the soil surface.

“When we dig into that closed trench, we find that the seed is now sitting in the ground at about 1.5 inches to 1.75 inches, and that’s not what you want,” Dowdy says. Watch the video on Farm Journal TV .

The result of that shallow germination depth is a fundamental threat to corn, Iowa State Extension reports. Shallow germination can impact early root development and contribute to rootless corn syndrome, susceptibility to herbicide injury, poor drought tolerance and other issues that can impact growth and development throughout the season and, ultimately, reduce yield.

(Farm Journal TV)

To combat this, Dowdy’s philosophy is simple: trust what you learn using a shovel to dig behind the planter to locate the seed; don’t depend only on what the planter monitor in the tractor cab shows.

Dowdy and Hula advocate for establishing a consistent germination depth for seed corn across the field, ensuring that plants have the strong foundation they need to thrive.

“For proper root development, we like to maintain a consistent two-inch germination depth,” advises Dowdy, who’s based near Valdosta, Ga.

Dan Quinn, Purdue University Extension corn specialist, says the “most common seeding depths recommended for corn range between 1.5 and 2 inches deep, and these planting depths can work very well within most conditions, however, certain soil moisture conditions at planting may warrant further examination/change in seeding depth.”

This year, with dry soil conditions in the Southeast, farmers have had difficulty achieving a 2-inch planting depth consistently for good emergence. Dowdy’s directive to growers in dry ground is to account for the “settle” in soils at planting by adjusting planter settings to go a bit deeper with planting.

Iowa State Extension agrees, noting that a 3-inch depth is usually OK in drier soils. While deeper planting can take slightly longer to emerge, it can lead to more uniform stands compared to shallow planting.

“My advice in these (dry) conditions is to plant a bit deeper, knowing the ground will settle, and you’ll get better root development,” Dowdy says.

By prioritizing the physical reality of the seedbed over the digital feedback in the cab, Dowdy believes farmers can unlock better performance without any additional overhead. By doing so, growers “will do a better job, and you’ll have proper root development and help you on your yields for free,” he says.

EPA Opens Public Comment Period On Draft Fungicide Strategy

Mon, 04 May 2026 16:19:42 GMT

The U.S. Environmental Protection Agency (EPA) is offering the U.S. public an opportunity to help shape the future of agricultural safety, unveiling a draft Fungicide Strategy designed to balance the needs of American farmers with the protection of the nation’s most vulnerable wildlife.

The proposal marks a significant step in the agency’s effort to meet its dual mandates under the Endangered Species Act (ESA) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). By creating a more efficient and transparent framework for pesticide registration, the EPA says it aims to “safeguard more than 1,000 federally endangered and threatened species” while ensuring growers maintain the tools necessary to protect the nation’s food supply.

A New Framework for Modern Farming

The draft strategy focuses on conventional agricultural fungicides across the lower 48 states — an area covering approximately 41 million treated acres annually. Rather than a one-size-fits-all mandate, the proposal introduces a three-step framework:

Identify Impacts: Assessing potential population-level effects on listed species.
Mitigation Planning: Pinpointing specific measures to reduce those risks.
Targeted Application: Determining exactly where these protections are most needed based on where endangered and threatened species live and how fungicides move through the environment.

The agency emphasizes that while this strategy guides future regulatory actions, it does not impose immediate requirements. Instead, the strategy serves as a roadmap for upcoming registration reviews, with the EPA promising public input on every specific action before it is finalized.

Balancing Innovation and Conservation

Saying that it recognizes farmers are the backbone of the U.S. economy, the EPA’s draft includes several updates to provide greater flexibility. Notably, the plan expands options for reducing spray drift buffer distances and introduces new mitigation tools, such as the use of “guar gum” as a spray adjuvant.

"[American farmers] need a diverse toolbox of innovative agricultural technologies to manage crop disease, prevent resistance, and produce the affordable, nutritious food that feeds our country,” the EPA says, in a press release. “The draft Fungicide Strategy is designed to ensure those innovative tools remain available and that they are used in ways that protect the environment and endangered species.

How to Get Involved

In a push for transparency, the EPA has opened a 60-day public comment period to gather feedback from scientists, conservationists, Tribal partners and the agricultural community.

Public Comment: Stakeholders can review the strategy and submit formal feedback via (Docket: EPA-HQ-OPP-2026-2973) through June 29, 2026.
Informational Webinar: The agency will host a public webinar on May 20, 2026, at 2 p.m. ET to walk through the proposal and answer questions. Register here .

The EPA expects to review all public input and finalize the Fungicide Strategy by November 2026.

Cold Snap, Wet Soils Put Corn on Hold, but Beans Still Get Green Light

Thu, 30 Apr 2026 20:54:36 GMT

A soaking rain has pulled much of the Midwest out of drought, but it’s also put the brakes on corn planting just as a cold snap settles in, says Ken Ferrie, Farm Journal Field Agronomist.

Ferrie explains that recent storms dropped anywhere from a half inch to 4” of rain across farmers’ fields and, with it, erased lingering drought stress and filled ponds that “will probably stick around a while.” The moisture, however, has saturated soils to the point that most of his planting “signal lights” for corn are now red.

“Due to wet conditions, most everyone is red at this point, and that doesn’t change until the soil is fit,” says Ferrie, who’s based in central Illinois. “We don’t mud in corn.”

Cold Spell Drives Conservative Corn Strategy

Ferrie bases his current recommendations on the close agreement between the Global Forecast System (GFS) and European weather models through May 9, both of which point to a stretch of cold conditions unfavorable for corn establishment.

“When they’re close together, the accuracy is usually higher and they both indicate a cold spell,” he says.

With that outlook, he’s cautioning growers across multiple regions to be conservative on planting corn especially until temperatures and soils improve. He emphasizes that while model divergence after May 9 could change the picture, he’s focusing on the 10-day window where the models agree to set planting guidance.

“Three days is a long time in weather forecasting, but they do seem to hit the temperatures closer than the rainfall amounts,” Ferrie says. “So, we’ll reevaluate on Monday to see how this forecast changes.”

Regional “Signal Lights” For Planting Corn

Ferrie uses a green-yellow-red “signal light” system to simplify planting decisions:

In areas around Jacksonville, Ill., and further south, conditions shift to a green light for corn starting Sunday noon, May 3, before turning more cautious midweek.
Along the U.S. Highway 136 corridor, he calls for a yellow light on May 3, switching to red by next Wednesday noon, May 6, likely holding through May 9.
In northern Illinois and around Iowa City, Ferrie highlights there will be rapid swings in planting opportunities as forecasts point to a seed-chilling event moving in.
In northeast Iowa (Cresco area), Rochester, Minn., and across much of Wisconsin, the guidance is straightforward: “It’s going to be a red light until May 9,” he says.

Across all these regions, Ferrie’s advice centers on patience with corn until soils are ready and the coldest temperatures pass.

The map released today shows the Midwest with only a handful of dry areas, unlike in the West and Southeast where farmers are seeing extreme drought to the degree that some have parked their planters for lack of rainfall.

(U.S. Drought Monitor)

Beans Offer Opportunity—If Ground Is Fit

Even as he urges caution on planting corn, Ferrie says the forecast still allows room for farmers to progress on soybeans where field conditions permit.

“We still have a green light on beans if the ground is fit,” he says.

He urges farmers to pay close attention to seed quality and stand establishment, especially where soybeans are untreated.

“Watch your percentage germ on your tag, especially if the beans aren’t treated,” Ferrie says. “You may need to bump those populations up a little for weed control.”

Most of the “frosted off” early beans in Illinois have already been replanted or patched, he notes, but some drowned-out ponded areas will likely need follow-up patching once water levels recede.

Manage Corn Risk In The “Yellow Windows”

For growers who have not yet put any corn in the ground, Ferrie recommends using upcoming yellow-light windows to strategically manage risk — without forcing corn into marginal conditions.

“If you haven’t planted any corn yet with the planter, and to mitigate some risk, you may want to get some corn planted in these yellow windows so you’re sure that you can put the hammer down when this cold snap passes through,” he says.

That approach, he explains, helps spread risk across planting dates, while still respecting soil fitness and seedbed quality. The goal is to avoid having all corn acres exposed to the same stress event, whether it’s chilling, crusting or prolonged saturation.

Ferrie encourages growers to stay tuned for updates as the forecast evolves, noting that temperature forecasts tend to be more reliable than rainfall projections in the short term. He directs farmers to ongoing updates and deeper discussion via his team’s online and audio channels.

Analysts Fear 2027 Could Be The Toughest Year Yet For Farm Margins

Thu, 30 Apr 2026 20:09:43 GMT

The most important tool on many U.S. farms this spring isn’t a tractor or a high-speed planter — it’s a pencil. Faced with climbing fertilizer costs, some growers are still hunched over spreadsheets and notepads as April shifts to May, trying to determine if corn or soybeans can pencil out.

Market analysts Naomi Blohm of Total Farm Marketing and Matt Bennett of AgMarket.net say they believe the current planting season remains in a state of flux as farmers’ input budgets are tightened to the breaking point.

According to a recent American Farm Bureau Federation survey, 48% of Midwest farmers say they cannot afford their full fertilizer needs for this season.

“Farmers who haven’t paid for fertilizer, are running behind, or are stuck out of the field due to weather are having to factor that into their decision-making,” Bennett says.

Blohm is seeing this reality play out in real-time with her clients. “Two of them openly shared this [past] week that they booked some fertilizer early and went with corn on those acres,” she reports. “But for the remaining acres, they had to stop and think it through and ultimately decided to switch to soybeans.”

Bennett notes that while soybean futures aren’t necessarily “explosive,” they could be a safer bet for cash-strapped operations. “If I’m a grower, and I’m sitting here trying to figure out whether I can make money putting $1,000, $1,100 [of nitrogen an acre] into this corn crop, I look over on the board on beans, and you’re looking at a price a lot of growers can make work just with average yields,” he says.

Blohm adds that what farmers decide to plant will be much clearer by USDA’s June 30 acreage report.

A Three-Year Financial Drain

The current financial stress isn’t happening in a vacuum. Bennett points out that consecutive years of financial pressure have taken their toll across the Midwest.

“The liquidity drain over the last three years has made it really tough for people, and we are even seeing an equity drain for some,” Bennett says. “When cash is this tight, it highlights why you might plant soybeans if you don’t have your anhydrous or urea on yet.”

The fertilizer crisis is fueled by global energy markets and geopolitical instability. Blohm points to India’s recent, aggressive moves to secure supply as a sign of things to come.

“I saw that India this week booked what they needed for fertilizer at double the cost,” she says. “But they don’t have a choice really, based on the amount of wheat that they grow in the world. They have to have a good wheat crop there, and they need that fertilizer.”

Bennett adds the issue isn’t just price — it’s access. “India bought 2.5 million tons of urea to front-run a potentially problematic situation,” he notes. “Disrupted natural gas facilities create a cascade effect that impacts anhydrous and urea production globally.”

2027: “It Scares the Daylights Out of Me”

While 2026 is beyond difficult, analysts are sounding the alarm for 2027. During an afternoon AgriTalk segment , host Michelle Rook asked if 2027 will be even worse.

“It scares the daylights out of me,” Bennett replied. “Projected cash flows and breakevens for 2027 don’t look good at all. Even if someone talks about $5 corn, you have to look at what you’ll have invested in it.”

Blohm agrees that the uncertainty is unprecedented. “Producers have to stay on their toes,” she says. “We don’t know if this shock will be a springboard for higher prices or if it will simply compress margins further.”

The Rotation Debate: Markets vs. Agronomics

How will crop rotations look by 2027? Farm Journal regularly reaches out to a vetted list of 80 ag economists from across the industry. Providing directional insights, the latest Ag Economists’ Monthly Monitor shows almost half of the respondents (seven of 16) to the April survey expect soybeans to gain more acres due to renewable diesel demand.

Northeast Iowa farmer Tim Recker sees some potential for a shift. “Renewable diesel demand underpins my local market,” he says. “I see value in policies that turn surplus crops into fuel, but we have to remember that Brazil is still eating our lunch in the global market.”

Central Illinois grain producer and hog producer Chad Lehman has a more cautious outlook.

“Pigs need corn,” Lehman says. “There are real risks with bean-on-bean rotations, including yield penalties and agronomic challenges. Even with more crush capacity, soybean meal prices remain strong, which reinforces the need for steady corn production.”

University of Missouri Agricultural Economist Ben Brown suggests that while “swing acres” might lean toward soybeans next season, many farmers will stick with their rotations.

“I believe 85% of acreage is determined by rotation,” Brown says. “That leaves only 15% to be adjusted based on outside influences.”

Long-Term Risks Of Changing Rotations

Shifting rotations in 2027 can’t be a financial decision only; it carries long-term agronomic consequences. Connor Sible, associate professor and row-crop field researcher at the University of Illinois, cautions that fertilizer cuts made this season could contribute to nutrient depletion in soils.

“If we pull back on nutrients now, those minerals are going to have to come from somewhere — likely the soil supply,” Sible says. “We want to maintain a healthy system over time, so we can’t go too far with input pullbacks.”

For those farmers already eyeing a move to soybeans in 2027, Sible recommends starting the planning process now.

“Think about what herbicide programs you are putting out this summer,” he advises. “You need to account for potential carryover effects if you switch the rotation in a field that was planned for corn to go with soybeans.”

Can Biologicals Fill The Gap From Reduced Fertilizer Use?

Tue, 28 Apr 2026 19:55:50 GMT

As thin margins and high fertilizer costs squeeze budgets, many corn and soybean growers are asking a hard question this spring: can biological products help out and pay their way in the field?

The answer depends on the goal, according to Connor Sible, University of Illinois field researcher and associate professor.

“Is the goal to get more out of what we’re already doing, enhance the yield in an already pretty intensive, progressive system?” he asks. “Or, are we trying to reduce inputs and then make up for that by maintaining yields with a biological?”

Sible studies high-yield corn and soybean systems and has spent years looking at how biologicals fit into real-world management. He says profitability hinges on getting a biological and a farming system to match. He offers two trains of thought on reaching a return-on-investment (ROI).

1. The Yield Response: Achieving a direct yield increase to offset the product cost.
2. The Efficiency Response: Improving nutrient uptake to maintain yields while reducing traditional inputs.

That framework for biological use underpinned the discussion during an Illinois Soybean Growers webinar on Tuesday: “Stretching Every Pound: Using Biologicals to Maximize Fertility During Input Shortages.” The program was hosted by the University of Illinois and Valent Biosciences.

Drew Harmon, Valent technical agronomist, provided an overview of row-crop farmers’ persistent struggles with accessing and covering the cost of fertilizer going into the 2026 season. He referenced recent American Farm Bureau and Bushel surveys showing the struggle underway across the Corn Belt and how the strain on farmers is changing their behavior.

(AFBF)

Nearly one-third of farmers Bushel surveyed said they will be doing more to manage costs and inputs this season.

(Bushel, Valent BioSciences)

“A lot of people are considering cutting their fertilizer by about 25%,” Harmon says. He reports that on his own farm, where soil tests are “on the higher end of a maintenance plan,” he and his tenant “decided to cut back our P and K by about a third this year.”

Cutting back fertilizer raises a practical question: how do crops still access enough nitrogen (N), phosphorus (P) and potassium (K) to perform and meet yield expectations?

One potential answer, Harmon and Sible say, is to use arbuscular mycorrhizal fungi, or AMF, especially where phosphorus rates are being reduced.

Harmon explains that mycorrhizal fungi are essentially a beneficial relationship that the fungi have with a host crop such as corn or soybeans. The root system supplies carbon through root exudates and, “in return for that carbon, the mycorrhizal fungi exchange nutrients and water.”

Applied as a seed treatment or in-furrow, AMF spores germinate in response to root exudates and colonize roots, then spread out as fine hyphae – branching, thread-like filaments – through the soil. That network effectively enlarges the rooting zone.

“Utilizing the mycorrhizal hyphae can expand the amount of surface area that [the crop] has to interact with, and it can expand that area by upwards of 50%,” Harmon says. “What that does is increase the opportunities for P and K uptake through diffusion, and it also allows greater access to soil water.”

In fields with lighter soils or facing recurring drought stress, that extended reach can be important. Even as much of the Midwest moves out of formal drought classification, according to the most recent U.S. Drought Monitor, Harmon notes that “we still can get those stretches of heat stress or stretches of flash drought… where we can see strain on our plants for needing water.”

Harmon also lays out an economic example for a typical two-year corn–soybean rotation under a biennial maintenance plan for phosphorus and potassium.

Using removal rates, yield estimates and recent DAP and potash prices, he calculates that a 25% reduction in P and K could offer “savings of mid-$40-ish per acre over a two-year period.”

The cost of using AMF in that scenario, he says, is about $6 per crop or just under $13 per acre over two years.

Arbuscular mycorrhizal fungi are essentially a beneficial relationship that the fungi have with a host crop such as corn or soybeans. The root system supplies carbon through root exudates and, “in return for that carbon, the mycorrhizal fungi exchange nutrients and water,” according to Drew Harmon, technical services representative for Valent Biosciences.

(Valent)

“AMF can be a potentially economical tool that could help increase nutrient uptake efficiency for the P and K that we’re reducing,” Harmon says, “while still protecting yield and preserving the majority of the fertilizer savings that you were looking to do.”

Harmon and Sible emphasize, however, that biologicals are not replacements for good agronomy—or for basic fertility.

“I don’t know a biological today that will fix a pH,” Sible says, as a for instance. “If we have a pH issue in the system, we probably need to resolve that before we go looking at new practices.”

A similar principle applies to nitrogen. Sible says nitrogen-fixing products can be useful as “a third source” of N, but they do not remove the need for a sound base rate.

“We often see an early-season biomass bump and higher kernel number potential [resulting from the biological product],” he says.

But to turn that into yield, the corn plant must have the nutrient resources to fill ears, which means adequate nitrogen and in-season management such as late fungicide use and/or supplemental nutrients.

For many farmers, another option this season for consideration is organic acids. Such products are positioned as biostimulants that support nutrient use efficiency, improve stress tolerance, and contribute to early growth.

Across both AMF and organic acids, Sible reminds growers that many biologicals are living tools, whether bacteria or fungi, and must be managed that way.

“A happy plant probably indicates happy microbes. Just like we need good conditions for plant growth, we need good conditions for microbial growth,” he says. “Plants need water, microbes need water. Plants need nutrients, microbes need nutrients.”
Harmon offers a similar caution on having the right set of expectations for using a biological.

“These products are not silver bullets,” he says. “They’re not fertilizer. They’re not going to [deliver] crazy amounts of yields. The majority of time you’re seeing it [improve] somewhere around 5% to 7% if you do see a biological response.”

Soybean Plots Put Biological Seed Treatments, In-Furrow Starter and Fungicides To The Test: What Really Pays?

Thu, 23 Apr 2026 21:22:08 GMT

The Farm Journal Test Plot season shifted into high gear this week as Ken Ferrie and his team push to get soybean plots in the ground ahead of the next round of rain.

“We planted until midnight last night to finish two plots, and we’ll finish two more today if the weather holds,” says Ferrie, Farm Journal Field Agronomist.

While planters are running full-tilt in parts of central and southern Illinois, Ferrie notes that northern Illinois is just finding its rhythm.

“Where we are today, farmers are just getting started again. If the rain forecast misses us, we’ll likely roll right through the weekend,” he says.

2026 Soybean Plots Take Shape

This week’s planting efforts focus on soybeans, with multiple test plots designed to tackle farmers’ questions regarding fertility, seed treatments and fungicide performance. Four key test plots being planted this week include:

Biologicals: A dedicated plot is focused on the performance of various biological seed treatments.
In-Furrow Starter: In a relatively uncommon setup for soybeans, the team is testing a special starter blend designed specifically for in-furrow placement.
Foliar Micronutrients: Ferrie and team will be applying micronutrients over the top of soybeans to evaluate the crop response and ROI.
Plant Architecture & Fungicide Efficiency: This plot compares non-branching varieties in narrow rows against branching “bush” beans. The goal is to measure how efficiently foliar products reach—and stay on—the target. “We want to see how much product hits the ground versus how much stays in the canopy,” Ferrie explains. “If I’m foliar feeding and it hits the ground, it’s a wasted investment. We’re tracking those efficiencies.”

Corn Is On Standby

While the soybean plots are ramping up, corn planting at the Farm Journal Test Plot sites remains largely on hold as the team waits for a better weather window.

Ferrie notes that while many farmers further south in the state are well underway with corn, his local fields south of Bloomington, Ill., have been slower to reach ideal conditions.

“We’ve given farmers the green light to plant corn in some areas of the state, but our specific ground is just now reaching the right moisture levels,” he says. “It has been a challenge to stay out of the wet spots, but we are ready to move as soon as the soil allows.”

Why Your ‘Worst’ Soybean Fields Should Be Planted First

Thu, 23 Apr 2026 16:31:23 GMT

When fields are ready to plant, soybean growers often head to their best ground first. Connor Sible is asking you to consider doing the opposite.

“If you want to maximize soybean yields across your entire farm — not just in one field — start by planting your lowest soil-testing fields first and save the highest soil-testing fields for last,” he advises.

That shift in focus is counter to what many farmers currently do, and it is at the heart of the planting strategy he recommends. The University of Illinois row-crop field researcher and assistant professor contends that it’s when and where you pull the planter into each field that can raise your overall farm average.

In practice, that means when an early planting window opens in April or the first of May and several soybean fields are dry enough for a green light, the first acres you plant should be the ones with lower soil test values — not the “good” fields on the soil test map.

“This gives the late-planted soybean the advantage it needs to put on more bushels relative to early planting,” Sible says. “Between the soil testing data and the planting date response data we have, it makes a lot of sense.”

Why Early And Late Soybeans Behave Differently

Sible says there is a decade-plus of field trials from the University of Illinois comparing planting dates, soil tests, and yield responses, verifying that this change in planting strategy makes sense. The full study, led by Marcos Loman and advised by Fred Below, summarizes their findings and is available here .

Part of Sible’s explanation is that early-planted soybeans in April tend to yield more overall, but these beans grow slowly at first in cool, often wet soils with lower solar radiation. Their nutrient uptake is long and gradual.

“Early soybean, while yielding higher, has slower growth and probably doesn’t need fertilizer” he says.

Because those plants grow and require nutrients slowly, the soil can usually keep up with nutrient demand, even in lower-testing fields. That’s why he says early planting is the best “boost” you can give to weaker ground.

Later-planted soybeans, going in during late May or even into June, are going into a different environment: warmer soils, longer days and more solar radiation.

“Late-planted soybean, while lower yielding and a lower total nutrient requirement, grow so fast that if we want to optimize the return on fertilizer investment, it’s probably going to pay back better on late-planted beans,” Sible says.

Fast-growing late-May soybeans in Illinois pull nutrients at a higher rate, and Sible’s data shows they respond more strongly to higher soil test levels and applied fertilizer. That’s why he wants the best-testing fields held back for the later planting window.

“Late-planted beans grow so fast, the soil (fertility) probably cannot keep up,” he explains. “The late-planted soybean benefits more from that high soil test environment.”

How Farmers Can Implement The ‘New’ Planting Strategy

Sible is quick to acknowledge that in the real world, farmers will start the planting process in whatever field is fit at the time.

“Obviously you’re going to plant the driest field first,” he says, noting that central and northern Illinois have had recent rainfall.

But once more than one field is ready, he contends farmers can start making more intentional choices.

His recommended process for soybean planting looks like this:

Sort fields by crop and soil test.
Start out by grouping soybean fields by soil test levels — lower-testing and higher-testing, especially for phosphorus and potassium, but considering overall fertility.
Identify likely early-plant candidates.
Look at drainage, residue and soil type to consider which soybean fields typically dry out first. Within that group, mark the lower-testing fields.
Use early planting on “weaker” fields.
When an early planting window opens and several soybean fields are fit, move the planter to the lower soil-testing soybean fields first — those that usually don’t win the “yield contest” on your farm.
Reserve high-testing fields for later.
If weather or logistics push some soybean acres into late May or early June, prioritize the higher soil-testing fields for those later planting dates, where their strong fertility levels can support rapid growth.
Align fertilizer decisions with timing.
On early-planted soybeans, especially in lower soil-testing fields, be conservative with extra fertilizer unless there is a clear nutrient deficiency. On late-planted soybeans in high-testing fields, consider that any fertilizer investment is more likely to deliver ROI.

“If we line up planting date, soil test and fertilizer strategy, we can do a better job of maximizing soybean yield across the farm,” Sible says.

From Field-by-Field To A Higher Farm Average

Sible frames his planting strategy for soybeans as a mindset change. Instead of asking, “How do I make my best field even better?” he wants farmers to ask, “How do I pull my whole average up?”

“The principle is pretty simple,” he says. “Early planting is a powerful yield tool — use it where the soil is weakest. High soil fertility is a powerful growth tool; use it where beans are going in late and growing fast.”

Farmers won’t always see the highest absolute yield on those late-planted, high-testing fields, he acknowledges. Weather and your calendar date still matter. But he believes the relative performance and return on fertilizer can improve when planting order and soil tests work together.

For growers struggling to manage tight margins, it’s a strategy that costs nothing to try except a reshuffled planting list.

“Hopefully you can take these concepts back and take them to your acres,” Sible says. “It’s about getting the most from the whole farm, not just one field.”

Sible laid out his planting recommendations for soybeans during the 2026 Crop Management Conference at the University of Illinois.

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.”

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

Mon, 20 Apr 2026 18:47:21 GMT

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

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

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

Drought Reshapes Farmer Expectations

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

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

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

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

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

Crop Insurance As A Lifeline

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

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

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

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

Fertilizer Sticker Shock Hits Canadian Growers

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

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

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

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

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

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

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

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

Cropping Plans: Adjust Or Stay The Course?

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

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

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

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

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

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

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

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

Mon, 20 Apr 2026 16:42:15 GMT

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

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

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

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

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

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

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

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

Spring 2026: Going 100% Peking

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

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

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

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

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

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

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

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

Beyond Yield: Logistics And Longevity

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

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

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

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

Maryland Farmer Turns Stringent Fertilizer Restrictions Into An Opportunity To Innovate

Fri, 17 Apr 2026 19:13:18 GMT

On the Delmarva Peninsula, where every pound of fertilizer applied is regulated, Maryland farmer Temple Rhodes is rebuilding his corn production system from the ground up — literally.

“We are in the Chesapeake Bay watershed, so all eyes are on us,” Rhodes says. “I am 50 miles from Baltimore, 50 miles from D.C., 67 miles from Philadelphia. We are in a hotbed of regulation.”

For the past 25-plus years, Chestnut Manor Farms has operated under a state-mandated nutrient management plan that caps how much nitrogen and phosphorus can be applied. Rhodes says participating in the program is not voluntary.

“It is forced on us with no incentive. You just have to do it,” he says. “So, we have to reinvent ourselves. We have to start looking at other ways to do things.”

Rhodes grows corn, soybeans and wheat, along with a few acres of grain sorghum. He also runs a cow-calf operation and backgrounds a couple hundred head of steers each winter on cover crops. The diversity helps, but the real transformation is happening in how he feeds his 1,700-acre corn crop.

From Front-Loading To Spoon-Feeding

For years, the standard practice was to front-load fertilizer before planting and hope enough stayed in place through the growing season. Under tighter rules and scrutiny, Rhodes says that approach no longer works.

“We used to put 100% of our nitrogen up front, then plant a crop on it and expect it to be there all along,” he says. “That is where we find out we are making a mistake. We are limited in how much fertility we can put on, so we better get it on at the right time, in the right place, or we are going to run out.”

Today, Chestnut Manor relies on what Rhodes describes as a systematic, layered approach that can include planter-applied fertilizer (in-furrow and 2x2 programs), split in-season applications of nitrogen, extensive cover crops and biologicals.

“When you take a systematic approach to all these things, it becomes a different animal,” Rhodes says.

Most of his corn is grown using a strip-till system with strips built in the spring. State rules prevent him from applying fertilizer in the fall, so he must work ahead of the planter using modest rates of nitrogen and then follow up with in-season applications.

“My end goal is to grow 225 bushels per acre,” he says. “I am going to put about 0.7 pounds of nitrogen per bushel on my crop. I can get away with that if I spoon-feed it correctly. If I put it all down up front, I am going to need about 1.25 pounds. I’m saving a lot of fertility by doing it this way.”

Rhodes says Maryland’s regulatory framework ensures he stays within strict application limits. The state’s phosphorus usage tool combines soil samples, yield history, location and soil type into an algorithm that dictates what farmers can apply.

“You put your soil samples in, you put your yield goal in, and it spits out what you can put on,” Rhodes says. “If you say your yield goal is 250 bushels but your APH is only 180, that is not how it works. Your APH and your yield goal have to be very similar, or you are not going to get to put on what you want. They are going to tell you what you can put on. Period.”

A New Technology Takes Root

Working under those constraints, Rhodes has become aggressive about testing new technologies that promise better nutrient efficiency and stronger root systems. Not one to be painted into a corner, Rhodes stays open to all ideas of what could work within the state’s mandated parameters. One of those is a biostimuant from NewLeaf Symbiotics.

The product is a non-GMO, naturally occurring bacteria known as PPFMs (Pink-Pigmented Facultative Methylotrophs), often called “M-trophs”. The PPFM-powered biostimulant is designed to improve crop yield, nutrient uptake, and stress tolerance, according to NewLeaf.

In the process of trialing the product, Rhodes shared the technology with XtremeAg, a group of seven farmers across the country who rigorously test new technologies in different environments.

“If we can test a product at multiple locations — a guy from Iowa, a guy from Maryland, a guy down South — and it works across everybody, that is big,” Rhodes says. “It is huge, because what works for me might not work for the guy in the Midwest. It all goes back to soil type and environment.”

Rhodes says what he was looking for from the biostimulant was stress mitigation and nutrient scavenging that can improve his current foundation for the future.

“I need a massive root system that can go out and get more nutrients, because I am limited on how many nutrients I can put on,” he says. “If I build a plant that scavenges more, that is a home run for us.”

Cutting Irrigation And Boosting Biomass

Rhodes farms a mix of acres, with about 25% irrigated and 75% dryland. After the first year of trialing the NewLeaf technology he found he didn’t need to run his irrigation system as frequently.

“The root system and the plant that it makes, I do not have anywhere near the stress,” he says. “When it’s hot and dry we would normally run the irrigation system, but I found I do not need to put on as much water.”

With irrigation costing about $125 per acre, every pass he eliminates adds up to a significant savings.

“If I make 12 passes a year, I can save $10 an acre just by not turning it on one time,” he says.

Beyond water savings, Rhodes estimates he is getting 30% more biomass in the plants.

“We actually cut corn stalks off at the ground and weighed them. We did not even measure the roots — just the plant itself. Thirty percent more biomass than my grower standard practice,” he says.

The biomass offers a payoff for grain production and nutrients for his cattle operation.

“I chop silage, so if I can add 30% more, that is 30% fewer acres I need to chop,” he reports. “It costs me by the acre, so 30% less is massive. And the nutrients in that plant are higher than in my grower standard practice. It all follows each other.”

Learning Curve And Next Steps

While the product delivers more biomass and higher yields, it did create new management challenges. Rhodes discovered the downside of building a much bigger plant on a tight nitrogen budget.

“In my system, I put about 30% of my nitrogen needs down with my strip till. I plant on top of it, everything looks great, it makes this massive system — and then I end up running out of nitrogen later in the season,” he recalls.

He spotted the problem at harvest, with many ears showing considerable tip-back of an inch or two. Rhodes figures the crop just “outran” his nitrogen program. Even so, the fields containing the experimental treatment still out-yielded his standard fields by an average of 11 bushels per acre.

The experience pushed him to rethink nitrogen application timing and total rate.

“I’m pulling some of the front-end nitrogen out and putting it into reproduction, so I do not run out at the end,” he says. “Instead of 0.7 pounds per bushel, maybe I can go to 0.8 or 0.9, maybe even one-to-one, and still be efficient because of what this product is doing.”

The results from the past two years of field testing are strong enough that Rhodes is no longer treating the technology as a small trial.
“We plant about 1,700 acres of corn, so it’s going on every acre of corn,” he says.

On a tightly regulated farm in the Chesapeake Bay watershed, Rhodes is betting that bigger roots, smarter fertilizer use and careful experimentation with nutrients will keep his operation profitable — all while staying within the rules.

Why Your Herbicide Can Fail Even if You Follow the Label

Thu, 16 Apr 2026 18:35:29 GMT

When weeds break through your herbicide, it’s easy to blame the product, rate or application timing. However, weed-control experts Greg Dahl and Joe Ikley suggest the real culprits might be something else altogether: the water in the tank and the adjuvant — or lack thereof — mixed into it.

Dahl, a retired research manager at WinField United, says hard data tells the story best. After reviewing thousands of university trials, he found
that skipping the herbicide’s required adjuvant is an invitation for weed-control failure.

“We saw a 30% to 90% reduction in weed control when the adjuvant was left out,” Dahl says. “That’s a pretty big sting.”

But simply using an adjuvant isn’t enough. The trials showed that using the wrong class of adjuvant in the tank can slash performance by up to 50%. Even settling for a “good enough” product over a premium version can result in a 25% drop in efficacy. Notes Dahl: In the world of weed control, “close enough” often isn’t.

(Council of Producers & Distributors of Agrotechnology)

Solutions That Work

Hard water in the spray tank is often a contributor to poor weed control. When spray water is loaded with calcium and magnesium cations, that can create a hostile environment for weak-acid herbicides like glyphosate. These minerals physically bind to the herbicide, forming particles the plant cannot absorb.

“Plants don’t eat rocks,” says Ikley, a weed specialist at North Dakota State University Extension.

To counter this, he and Dahl recommend using ammonium sulfate (AMS) as a dedicated water conditioner. Dahl’s research indicates that in cases of extreme hardness, adding at least 8.5 lbs. of AMS per 100 gallons is necessary to fully neutralize the water and restore herbicide efficacy.

However, the battle isn’t just in the tank; it’s often on weed leaves. Ikley points out that certain weeds, like velvetleaf, actually secrete their own calcium crystals onto their leaf surfaces.

“Several of our weed species actually need higher AMS rates because of the crystals on the surface of that leaf,” Ikley explains. “We have to account for that interaction on the weed surface, not just in the water.”

While “all-in-one” adjuvant blends offer convenience, Ikley and Dahl urge caution. To hit a specific price point or fit multiple ingredients into the jug, manufacturers sometimes compromise on the water-conditioning component. University trials consistently show that very few “convenience” products can outperform the gold-standard combination of AMS plus a nonionic surfactant, Ikley and Dahl say.

Conditioners Aren’t All Created Equal

Dahl and Ikley both note that water conditioners and “all-in-one” adjuvants vary widely in performance. To get everything into a gallon and hit a certain price point, they say manufacturers sometimes compromise and come up short on one of the functions, often the one for water conditioning.

Ikley says university trials show only a handful of conditioners outperform the standard combination of AMS plus a nonionic surfactant.

“A few of the water conditioners do quite well,” he reports. “The rest don’t perform as well as AMS plus surfactant.”

Before they select or change the adjuvant used, Dahl and Ikley tell farmers to test their water, and ask the laboratory to report the results to them in parts per million.

“Some labs report in grains, and then you’ve got to do more math,” Dahl says.

Ikley adds a practical tip: always run the water for a few minutes before taking a sample to ensure you aren’t testing stagnant residue from the lines.

Ultimately, adjuvants are a valuable safety net for herbicide performance and weed control. As Dahl puts it, “You can raise herbicide rates until you can’t anymore. When you need help, the adjuvants can help.”

Treat Soil Moisture Like A Checkbook To Sharpen Irrigation Decisions

Tue, 14 Apr 2026 21:06:30 GMT

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

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

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

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

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

Why Seasonal Totals Can Mislead

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

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

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

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

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

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

Build A Simple Water-Balance Ledger

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

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

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

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

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

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

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

Adapting The Method To Different Climates

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

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

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

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

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

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

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

Match Irrigation To Crop Root Depth And Soil Type

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

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

For farmers, that means:

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

Using The Ledger To Time Irrigation

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

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

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

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

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

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

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

Adding Sensors And ET Tools To The Checkbook

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

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

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

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

Manage Water Like Money

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

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

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

4 Agronomic Pillars Every Corn Grower Needs

Mon, 13 Apr 2026 18:50:44 GMT

What if the next 10-bushel bump on your corn ground doesn’t come from a new product or technology but from how deep you set the planter and where you placed nitrogen? Dan Quinn, Purdue University corn specialist, says the biggest yield gains still come from decisions that sound simple on paper and are hard to execute in the field.

For Quinn, a winning season hinges on four pillars: plant deep enough for consistent moisture, protect uniform emergence and roots, respect nutrient interactions, and use technology and timing to manage risk — not to shortcut agronomy.

“Fundamentals are fundamentals for a reason,” Quinn says. “If something’s off… you’re not going to get any benefit from some of those more progressive practices.”

Here are the four recommendations he offers growers to get a strong start this season:

1. Consider Moisture Availability, Not Just Planting Depth

A successful season begins at the planter, but Quinn warns against getting comfortable with a “standard” depth. He argues that corn should be placed where moisture access is reliable, even if that means pushing seeds deeper than your traditional comfort zone.

“I’d rather be a bit on the deeper side than the shallow side,” Quinn says. “We’ve done some seed depth work showing corn can get out of the ground at 4 inches deep.”

While his typical target is a 2-inch depth, he advises growers to move deeper in dry conditions. The primary goal, he advises, is to ensure every seed sits in the same soil and moisture conditions to trigger uniform germination.

To complete the imbibition (water uptake) phase of germination, corn needs to absorb 35% of its weight in moisture, according to University of Nebraska Extension research . When adequate soil moisture is available, this typically occurs within 48 hours.

2. Protect Uniform Emergence And Early Root Growth

Quinn calls corn “a pain” because it offers little to no forgiveness when emergence is uneven.

“We have to get it out of the ground at the same time,” he says. “It has to be uniform, it has to get out of the ground quickly, and it has to get that root system established and moving.”

When a field looks off, Quinn said that nine times out of 10, the problem can be identified below the surface. Issues like fertilizer salt injury, compaction, or heat desiccation in sandy soils often start early but don’t manifest visually until weeks later.

“We see more often than not that if you have problems… a lot of times you can point back to that root system,” he says.

3. Master The N:S Ratio And Starter ROI

As yield targets climb, the conversation is shifting from “how much nitrogen” to “how does nitrogen interact with other nutrients.”

Quinn is specifically watching the relationship between nitrogen (N) and sulfur (S).

“Nitrogen and sulfur behave very similarly in the plant. They’re kind of joined at the hip,” he says.

Purdue research shows that high nitrogen rates can actually induce sulfur deficiency by throwing off the plant’s internal balance. As you push N rates and yield potential up, the crop’s sulfur demand also increases. If S isn’t increased proportionally, sulfur can become a limiting nutrient in the system. Quinn currently recommends 15 to 25 pounds of sulfur per acre, though he believes that might be a bit low in a high-yield system.

Additionally, Quinn remains a staunch advocate for starter fertilizer. Beyond the agronomic “safety net” it provides as corn transitions off seed reserves, he points to a secondary economic benefit: lower grain moisture at harvest.

“I’ve seen trials where just the drying savings from starter is enough to pay for the system, even beyond the yield benefit,” he says.

4. Use Tech As A Guardrail, Not A Crutch

While Quinn supports the use of variable-rate planting and advanced sensors, he views them as tools to manage risk rather than replacements for boots-on-the-ground agronomy.

He highlights hydraulic independent downforce as a game-changer for maintaining consistency in variable soils. However, he notes that even the best technology cannot fix a poor timing decision. In Indiana, this has led to increased reliance on sidedress nitrogen to limit exposure to unpredictable spring weather.

“It helps reduce some of the risk and vulnerability,” Quinn says. “It’s about making sure we do what we can to maintain having that nutrient available for the plant when it needs it most.”

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.

A farmer a little south of me just shared these pics of him planting his relay beans… with the harvesting videos from last summer.

He’s not up to 285 acres and has plans to scale to 700+ next year revising to a 40’ system.

He’s finding this system to be much more profitable… pic.twitter.com/L6lvsM0E31
— Jason Mauck (@jasonmauck1) April 7, 2026

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.
