Title: Crop residue removal and tillage - Effects on soil erosion and nutrient loss in the corn belt

If no conservation practices were used, the rate of soil erosion would increase by about 33%. Crop residue removal for alternative use may intensify an already serious problem. In this study, the amounts of crop residues produced in the Corn Belt, the amounts of nutrients contained in the residue, and the effect of crop residue removal on soil erosion are calculated. The Universal Soil Loss Equation and current cropping practices are used to predict soil erosion for five residue and tillage management systems, to determine the amounts of residue that can be removed from the major land resource areas in the Corn Belt without undue damage to the soil. Results identify areas where crop residues feasibly may be removed for alternative use, and areas where crop residue in conjunction with conservation tllage systems is necessary to maintain soil erosion losses within tolerance limitsRead More
