Abstract

We calculated potential soil erosion by water land resource areas (MLRAs) in the Corn Belt using the USLE and current cropping practices. Annual erosion rates ranges from 44.7 metric tons per hectare in MLRA 107 to 9.7 metric tons per hectare in MLRA 103 for a conventional fall-plow, spring-disk tillage system with all residues removed. With no conservation practices applied, only 36% of the cultivated area in the Corn Belt would have a soil erosion rate less than or equal to the allowable limits established by the Soil Conservation Service. Use of tillage and residue management systems increases this area to 78%.-from Authors
