Washington D.C., USA – American farmers faced a staggering increase in fuel costs during the 2025–2026 planting season, according to a new study released Thursday by the Joint Economic Committee Democrats. The analysis found that farmers of key U.S. crops—corn, soybeans, wheat, cotton, and rice—spent a collective $1.4 billion more on diesel fuel than they did during the previous planting season, representing a sharp 63% year-over-year jump. The study underscores the significant financial pressure rising energy costs are placing on the agricultural sector.
The calculations were based on data from AAA and the Energy Information Administration, combined with estimates of average fuel use by crop and field operation from the USDA and Iowa State University Ag Decision Maker research, as well as USDA data on 2025 and 2026 acreage and planting windows for the five crop types. The impact was particularly pronounced in the nation’s heartland, with Illinois, Iowa, and Minnesota experiencing the highest overall increases in planting diesel costs. The analysis revealed that sixteen of the top 18 corn-growing states and all of the top 18 soybean-growing states were among the most affected.
The study also examined the cost to refill a farm’s onsite fuel tank, finding an average increase of $1,538 across 49 states. The largest price hikes were recorded in California, where farmers saw an increase of $2,037, followed by Washington ($1,878), Michigan ($1,850), Ohio ($1,815), and Indiana ($1,804). These rising input costs come at a time when farmers are already navigating volatile commodity prices and supply chain challenges, adding a significant burden to the cost of production. The report highlights how macroeconomic factors, including global energy markets, continue to have a direct and substantial impact on American agriculture.
