Abstract

6 crop sequences were evaluated in each of 14 MLRAs. In 13 of 14 MLRAs, weighted average estimated soil loss exceeds tolerable limits. The exceptioni is MLRA 153, Atlantic Coastal Flatwoods, where the greatest percentage of residues remains available after water erosion control needs are met. In all MLRAs, conservation tillage significantly reduces potential soil losses. In 4 of 6 states, 6.0M metric tons, or 60% of crop residues, are needed for water erosion control. In Alabama and Mississippi about 90% of the residues produced are needed for water erosion control.-from Authors
