How Ethanol Affects Corn Prices Corn prices near ethanol plants increase between five and eight cents per bushel. 1. 4 billion bushels went into ethanol production in 2004—and that affects overall corn supply and helps shore up corn prices nationwide. U. S. Department of Agriculture says ethanol production adds 30 cents to the value of a bushel of corn. The Renewable Fuels Association notes that ethanol production adds $4. 5 billion to U.
