Crops grown without tillage on claypan soils in the eastern Great Plains often yield less than with tillage, especially cereals that require careful management regarding N fertilization. The objective of this 20‐year study was to determine the response of grain sorghum and soybean in rotation to tillage and N fertilization on a claypan soil in southeastern Kansas.
