Beginning in 1999, two locations in Iowa (Chariton, Atlantic) were used to study the effects of corn residue grazing by beef cows on soil characteristics and soybean yields the following growing season. Cows were allowed to graze inside selected paddocks at monthly periods throughout the fall and winter. For a grazed and ungrazed comparison, grazing exclosures were used inside the grazed paddocks while one paddock was left ungrazed for a control. The use of this design was to determine if grazing had any adverse effects on soil characteristics and at what date and weather conditions did they occur. Also equal …
