Record-high diesel prices are threatening the financial viability of Ohio farm operations heading into the 2026 crop year, according to a group of Ohio farmers surveyed by Brownfield Ag News.

"It's really looking bad for our budgets," one farmer in the group said, describing how fuel costs are straining farm-level finances already stretched by the broader agricultural economy.

Scott Haerr, who farms in west central Ohio, said current conditions in the ag economy are making it difficult for producers to lock in what they need for harvest.

"We only pre-bought about 60 percent," Haerr said, referring to how much of his harvest-season needs his operation had secured ahead of the price run-up.

What does the fuel squeeze mean for the 2026 crop year?

The comments from Ohio growers capture a shift in sentiment: optimism that had built around the 2026 crop year is fading as diesel prices continue to climb. For full-time grain operations, diesel is a non-discretionary input. It powers tillage, planting, spraying, hauling and harvest, so price increases flow directly into per-acre cost structures.

Haerr's 60 percent pre-buy figure illustrates the exposure that remains. The portion of harvest needs not yet secured leaves those purchases subject to whatever the diesel market does next, and the farmers interviewed say the current pricing environment is eroding margins that were already thin.

The growers' warning — that record fuel prices could threaten financial viability rather than merely compress profits — marks the severity they attach to the run-up. Brownfield's report is a grower-condition account based on farmer interviews, not a forecast of prices or a tally of harvested results, and it should be read as an on-the-ground signal of input-cost stress in the western Ohio corn belt.

What comes next?

Farmers like Haerr will be watching whether diesel prices retreat before the balance of harvest needs must be purchased, and whether the remaining 40 percent of pre-buy coverage gets locked in at workable levels or at record highs as the 2026 crop year approaches.
