University of Illinois February 2018 This publication presents revenues and costs for producing corn, soybeans, wheat, and double-crop soybeans in three regions of Illinois: northern, central, and southern Illinois. Central Illinois is further divided into categories for high-productivity farmland and low-productivity farmland. Divisions between high and low farmland productivity are made based on soil productivity ratings. Generally, farms with higher soil productivity ratings have higher yields. Between 2011 and 2016, corn yields on high productivity farmland averaged 192 bushels per acre while corn yields on low productivity farmland averaged 179 bushels. This publication includes ten tables: 1. Corn Revenue and Costs, Northern Illinois 2. Soybean Revenue and Costs, Northern Illinois 3. Corn Revenue and Costs, Central Illinois with High Productivity Farmland 4.
The average corn yield is forecast at 140 bushels per acre, down 14 bushels from last year. Acreage harvested for grain is estimated at 370,000, up 10,000 acres from last year. Soybean producers currently expect to harvest 590,000 acres with an average yield of 40 bushels per acre, up two bushels from last yearâs yield.
