Abstract

A two-year experiment was designed to determine the impact of grazing corn residue during the spring on subsequent soybean yields in a corn-soybean rotation. Tillage treatments consisting of ridge-till, fall-till, spring-till, and no-till were also evaluated to determine if yields could be maintained by alleviating compaction from grazing in the spring. Grazing treatments overall, and specifically in the ridge-till and no-till systems, resulted in increased yields. Residue cover was also more sensitive to changes in tillage rather than grazing; however, both treatments decreased residue cover.
