Abstract:

The Universal Soil Loss Equation (USLE) has been revised to more accurately estimate soil loss from both crop and rangeland areas. Major revisions affecting rangeland soil loss estimates include new 'R' factors for the Western United States, a subfactor approach to determine the 'C' factor and a 'LS' table for rangeland. Measured soil losses from erosion simulation plot studies on rangelands throughout the Western U.S. were compared to soil losses estimated by the Revised Universal Soil Loss Equation (RUSLE). Correlations between measured and predicted soil loss varied among the 17 sites tested. The RUSLE factor values are examined and related to special conditions found on rangelands.
