View source for Universal soil loss equation

'''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.
