-'''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.
