Abstract

Crop rotation may influence crop yield by changing the availability of several nutrients and water, several soil physical properties, and incidence of diseases, pests, or weeds. Including grain legumes (such as soybean) or forage legumes in a rotation, usually increases soil nitrogen (N) supply for corn in subsequent years. A long-term crop rotation study was initiated in 1979 at the Iowa State University Northeast Research and Demonstration Farm, Nashua, Iowa, to assess the effects of various crop rotations and N fertilization of corn on crop yield.
