The purpose of this study is to evaluate a continuous corn rotation and a corn-aftersoybean rotation to compare their effects on yield.

Crop rotation provides a break in the accumulation of crop specific diseases and pests. Because of the increase in disease and insect pressure, long-term mono-cropping systems often suffer a yield penalty. In the second year of this study, we have yet to see any yield penalty in a corn following corn rotation which could be due, in part, to the relatively small size of this plot.
