I have spent a lot of years walking fields, pulling soil samples, and helping growers make decisions that protect their bottom line. And I will be straight with you: heading into the 2026 growing season, the margin for error is as thin as I have seen it in a long time.
That does not mean 2026 has to be a bad year. It means it has to be a smart one.
Here is what I am watching, and what I think every Midwest corn and soybean grower should be thinking about right now.
Nitrogen Costs Are the Number You Cannot Ignore
Fertilizer is where the 2026 budget conversation gets serious fast. Nationally, fertilizer alone is projected to account for roughly 36% of a corn grower's total operating costs. In Illinois, corn growers are expected to spend around $229 per acre on fertilizer in 2026, a figure that keeps creeping upward even as corn prices stay stubbornly flat.
Nitrogen specifically is the culprit. Wholesale nitrogen prices were up 25% to 45% depending on the product heading into this season, driven by the ongoing conflict in Europe, trade restrictions out of China, and global supply chain disruptions. Anhydrous ammonia bids in the $730 to $740 per ton range were reported in early fall 2025. That is still historically elevated compared to the 2017-2020 range that most growers remember as "normal."
What does that mean in practice? Every pound of nitrogen you over-apply or lose to the environment this season is money you are not getting back. This is exactly why precise, field-by-field fertility planning is not a luxury in 2026 — it is one of the only real levers growers have left on the cost side of the ledger.
At Gill Ag, we have been using multi-year soil data and customized fertility programs to help growers stretch their nitrogen investment without sacrificing yield. Agronomists who work the same fields year after year are not just providing a service; they are building a history that lets you make smarter calls when the margin is this tight.
Lessons from 2025 That Should Shape Your 2026 Plan
The 2025 season taught us a few things worth carrying forward.
Early-planted soybeans outperformed consistently across the Midwest. Agronomists from Iowa State, Ohio State, and the University of Minnesota all noted that fields seeded earliest tended to yield best, particularly where residual herbicides kept weed pressure in check from the start. If you have been a mid-May soybean planter out of habit, 2025 gave you a compelling reason to reconsider.
Sudden death syndrome showed up in roughly 70% of fields north of Interstate 80 in parts of Iowa. Dry conditions at planting reduced early infection pressure in some areas, but growers who selected genetics with SDS resistance had a meaningful edge when moisture arrived later. Going into 2026, that lesson is worth baking into your seed selection now.
On the corn side, disease pressure — particularly southern rust — created headaches in a number of fields. 2025 was a reminder that scouting is not optional. A good crop scout, as one agronomist put it plainly, will make the farm money. That is not marketing language. That is what the data showed.
What Gill Ag Is Watching for Spring 2026
A few things are on our radar as planting season approaches.
Acreage shifts. With soybeans showing better relative profitability and USDA projecting a meaningful uptick in soybean acres, corn ground is going to face more competitive pressure. We are advising growers to revisit their rotation plans with current price signals in mind rather than defaulting to what they planted last year.
Phosphate availability. Fall phosphate applications in North America were down roughly 20% from normal heading into 2026 as growers cut costs. That deferred application has to be made up somewhere, and spring demand for phosphate could spike accordingly. If you did not apply in the fall, get your plan locked in now before supply tightens and prices follow.
Nitrogen stabilizers. With nitrogen prices where they are, losing applied N to leaching or volatilization is not something you can afford to shrug off. At around $14 to $15 per acre, a nitrogen stabilizer with anhydrous ammonia applications is one of the better investments available right now in terms of protecting the nitrogen you already paid for.
Breakeven math. Corn breakeven on average soil is projected at around $5.35 per bushel in 2026, with even optimistic market scenarios putting fall 2026 corn prices between $3.90 and $5.10. If you are not running field-level cost of production numbers and building a marketing plan around them, you are guessing. And in this environment, guessing is expensive.
The Bottom Line
2026 is not a year to wing it. It is a year to be methodical, data-driven, and honest about where your costs are and where your opportunities are.
The growers who come out ahead this season will be the ones who made their input decisions early, locked in product before demand spiked, managed their fertility programs with precision, and leaned on agronomic expertise to avoid the costly mistakes that tight margins simply will not absorb.
That is what Gill Ag is here for. We work with growers across the Midwest to build customized corn and soybean management plans grounded in real soil data and long-term field history — not generic recommendations. If you want to talk through your 2026 plan, we are ready.
