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 Illinois Society reported a 2013 midpoint cash rent of $285 per acre for farmland with expected yield between 150 and 170 bushel per acre. In the calculations above, lower productivity farmland with a 160 bushel per acre corn yield has $211 per acre of operator and land return (see Table 1).n this case, the farmer receives $50 per acre ($350 operator and land return - $300 cash rent). When cash rents exceed operator and land returns, the farmer faces losses. As shown in Table 1, operator and land returns are calculated for three different farmland productivities: High, low, and lower.
