Line 1:
Line 1: − '''Universal soil loss equation''' or USLE is an [[erosion]] model designed to predict the long-term average soil losses in runoff from specific field areas in specified cropping and management systems. + − The equation is: A = RKLSCP − where A = Computed soil loss per unit area − R = Rainfall and runoff factor − K = Soil erodibility factor − L = Slope-length factor − S = Slope-steepness factor − C = Cover and management factor − P = Support practice factor − The NRI calculations use location-specific data for the field in which the NRI sample point falls or that portion of the field surrounding the point that would be considered in conservation planning. − ==References== − [http://www.nrcs.usda.gov/technical/NRI/1997/summary_report/glossary.html List of USDA terminology] <br> − [[Category:Agriculture]] − {{USDA_Terms}}
