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 first two columns of Table 1 shows corn and soybean budgets for central Illinois farmland with lower productivity. Expected yields are 184 bushels per acre for corn and 53 bushels per acre for soybeans (see 2016 Illinois Budgets for other yield levels). Prices are $4.00 per bushel for corn and $9.25 per bushel for soybeans. These prices are relatively optimistic compared to 2016 fall delivery bids, which are near $3.70 per bushel for corn and $8.70 per bushel for soybeans. Note that very low prices are not needed to induce the need to cut costs.
