Completed Competitive Grant

Soil quality, yield stability and economic attributes of alternative crop rotations

Project ID: 1998-05

Abstract

Three long-term rotational crop studies in Iowa and one in Wisconsin were examined for conclusive evidence of rotational effects on soil quality. Long-term yield data also were evaluated to determine if there was a quantifiable relationship between soil quality and yield or yield stability.
