A recent study investigated the effects of long-term cropping systems on corn grain yields, yield trends, and yield stability over the last 16 years of a long-term fertility and cropping systems experiment. This study suggests that on average in a productive Central Pennsylvania soil, the yield of corn rotated with alfalfa, red clover and timothy is modestly higher and less variable than corn grown exclusively.
