Farmers Face Sharp Rise in Diesel Costs During Planting Season

By Andi Anderson

U.S. farmers experienced a major increase in fuel expenses during the 2025-2026 planting season, adding financial pressure to farm operations across the country. According to a new study by Joint Economic Committee Democrats, producers of major crops spent approximately $1.4 billion more on diesel fuel compared to the previous planting season.

Successful Farming’s Mariah Squire reported that, “a new study by Joint Economic Committee Democrats found that farmers of key crops in the U.S. spent $1.4 billion more on diesel fuel during the 2025–2026 planting season than they did last season.”

The study examined diesel use for planting corn, soybeans, wheat, cotton, and rice. Findings showed that diesel spending increased by 63% year-over-year, highlighting the effect of rising energy prices on agricultural production. Researchers used data from AAA, the Energy Information Administration, USDA, and Iowa State University Ag Decision Maker research to estimate fuel consumption and planting costs.

The analysis revealed that Illinois, Iowa, and Minnesota recorded the largest overall increases in planting diesel expenses. In terms of total spending increases, Illinois led with an additional $163.2 million, followed by Iowa at $151.1 million and Minnesota at $101.7 million. Nebraska and North Dakota also reported significant increases.

Successful Farming’s Mariah Squire reported that, “Sixteen of the nation’s top 18 corn-growing states were included in the top 20 states affected.”

The impact of higher diesel prices extended beyond planting activities. Farms.com reported that, “according to the findings, the average farmer paid approximately $1,500 more to refill a typical on-farm fuel tank compared to peak costs experienced during the 2025 planting season. Nationwide, the added cost to refill a farm fuel tank reached an average of $1,538.”

In addition, fuel expenses for farm machinery and transportation vehicles increased considerably. Filling a grain truck cost about $205 more, while refueling a typical tractor required roughly $250 more than previous levels.

Farm groups continue to watch energy markets closely as rising costs remain a key concern. Higher expenses for fuel, fertilizer, and transportation are affecting farm budgets and profitability. Experts note that increased diesel prices may influence machinery purchases, crop choices, and operational decisions in future growing seasons. As farmers prepare for upcoming seasons, managing fuel costs will remain an important challenge for maintaining efficient and profitable agricultural production.
