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.
