The Trump administration announced more than $15 billion in payments, loans and assistance for US producers, including about $8 billion in one-time diesel-cost payments and $13.8 billion in 2025 safety-net payments covering corn, soybeans, wheat and rice. Diesel averaged $6.32 a gallon, 70% above a year earlier.
Large farm aid cushions producers against high diesel and input costs and could sustain planting demand for feed grains, but the payments themselves do not change physical supply.
