A perfect storm on the Great Plains

The question “Am I out?” is being asked across the Kansas wheat belt this spring—not as existential dread, but as practical arithmetic. For the first time in memory, farmers are calculating whether the Revenue from a single bushel of hard red winter wheat will cover the diesel burned to plant it. According to the Kansas Department of Agriculture, the state’s wheat acreage has fallen 12% year-on-year as growers idle marginal land rather than shoulder losses. The trigger—a convergence of a once-in-a-century drought and a geopolitical flashpoint in the Strait of Hormuz that has rerouted global energy flows.

Whilst drought alone would strain cash-flow, the Iran war has amplified the shockwave. The disruption to Gulf oil shipments has pushed marine fuel prices up 28% since April, according to data from the U.S. Energy Information Administration. At the same time, the closure of key fertiliser export terminals in Iran—and sanctions-related shipping delays—have lifted granular urea prices 35% above 2025 averages, reports the International Fertilizer Association. The arithmetic is brutal: for a Nebraska corn farmer, fertiliser now represents 42% of pre-harvest costs, versus 28% in 2021.

Farmers are responding by trimming applications—risking Yield penalties next season. “We used to put down 200 pounds of nitrogen per acre; this year we’re at 150,” says Dale Harman, a fifth-generation wheat grower in Colby, Kansas. The Kansas Wheat Commission estimates that such cuts could shave 8% off regional yields. Yet without the cuts, Harman reckons he would haemorrhage another $50,000 on 1,200 acres. “I’m not sure which is worse.”

From fuel pumps to fertilizer plants: the Supply-chain squeeze

The pain radiates through the entire agricultural supply chain. Marine diesel—used by barge operators on the Mississippi—has climbed to $4.12 per gallon, up from $3.20 in January, according to data from the American Waterways Operators. The extra cost is being passed Upstream: Archer-Daniels-Midland (NYSE: ADM) reports that inland freight for fertiliser has risen 15% since March. Meanwhile, CF Industries Holdings (NYSE: CF) has idled two ammonia plants in Louisiana due to high gas feedstock prices—further tightening nitrogen availability.

The Strait of Hormuz standoff has not only raised fuel prices but also rerouted LNG tankers, pushing Henry Hub Natural Gas futures 22% higher since late March. Fertiliser manufacturers rely on gas as a feedstock; higher gas prices directly inflate the cost of urea and ammonia. “Every 10-cent increase in gas prices adds $1.80 per tonne to our production cost,” says Tony Will, CEO of CF Industries. The company has deferred $300m of planned capital expenditures to preserve cash.

Logistics bottlenecks are compounding the squeeze. Congestion at the Port of Houston—where 40% of US fertiliser imports arrive—has added three days to vessel turnaround times, according to Port of Houston Authority data. The delay has pushed spot fertiliser prices in the Midwest to $840 per tonne for urea, up from $620 in January. “We’re seeing farmers charter private trucks from Oklahoma just to avoid the port chaos,” says a grain merchandiser in Wichita.

The drought wildcard: when the sky is the only limit

The drought gripping the Southern Plains is the most severe since the Dust Bowl era, according to the U.S. Drought Monitor. Soil moisture deficits in Kansas and Oklahoma exceed 30-year averages by 40%, curtailing early planting and reducing subsoil recharge. The National Oceanic and Atmospheric Administration projects that wheat yields in Kansas will fall to 34 bushels per acre—down 22% from the five-year average.

Whilst farmers typically hedge against price Volatility using futures contracts, the drought has eroded their Collateral base. Lenders in the Farm Credit System are tightening advance rates on stored grain; the Kansas City Federal Reserve’s latest agricultural credit survey shows that 23% of farm Loan officers have reduced operating lines by an average of 15%. “Banks are asking for additional collateral that we simply don’t have,” says a fourth-generation farmer in Hugoton who requested anonymity.

The drought is also accelerating structural decline in the region’s aquifers. The Ogallala Aquifer—source of 30% of US irrigation water—has seen water levels fall by 18 feet in the past decade in parts of Kansas, according to the U.S. Geological Survey. Farmers are drilling deeper wells at a cost of $2,500 per foot, further straining balance sheets. “We’re one dry year away from abandoning 30% of our irrigated acres,” says a farmer near Garden City.

Policy gridlock meets market reality

Washington’s response has been muted. The Biden administration’s $1.2bn aid package for drought-stricken farmers—announced in March—covers just 12% of projected losses, according to the American Farm Bureau Federation. A bipartisan bill to expand crop insurance subsidies stalled in Congress after disagreements over budget offsets. Meanwhile, tariffs on Russian fertiliser—imposed in 2022—remain in place, preventing cheaper alternatives from reaching the market.

Whilst some lawmakers advocate for strategic fertiliser stockpiles, industry analysts caution that such measures would distort markets and delay necessary supply-chain adjustments. “A stockpile would only paper over the problem,” says Joseph Glauber, senior research fellow at the International Food Policy Research Institute. “The real solution is diversifying supply chains away from the Gulf and investing in precision agriculture.”

The Federal Reserve’s interest-rate pause has done little to ease farm Debt burdens; the average Interest Rate on farm operating loans now stands at 8.75%, up from 5.5% in 2021. “We’re borrowing at double-digit rates to plant crops that may not break even,” says a Missouri soybean grower. Analysts at CoBank forecast that farm debt delinquencies could rise to 6% by year-end—double the historical average.

Who will blink first?

The standoff in the Strait of Hormuz shows no sign of resolution. Iran-backed Houthi rebels continue to target commercial vessels, while the U.S. Fifth Fleet patrols the region. The International Maritime Bureau reports that 12% of global seaborne oil transits have been rerouted since April, adding an average of $2.30 per barrel to global shipping costs.

Farmers, meanwhile, are making irreversible decisions. In Texas, 8% of wheat acreage has been left fallow—a record since 1988. In Oklahoma, some cattle ranchers are selling herds early to free up cash, depressing local beef prices. The USDA’s latest crop progress report shows that only 42% of corn has been planted—well below the five-year average of 63%—as farmers wait for soil moisture to improve.

The question “Am I out?” is no longer rhetorical. For many, it is a calculation of survival. The USDA estimates that net farm income will fall to $115bn in 2026—down 27% from 2025 and the lowest since 2010. Without a reprieve on fuel, fertiliser, or weather fronts, the Great Plains could see the largest exodus of farmers since the 1930s.
