WebA = R×K× LS×C× P A = R × K × LS × C × P. Where A is the annual soil loss (tons/ac), R is the rainfall erosivity, K is the soil erodibility, LS is the combined factor of the length of slope and the slope gradient, C is for cover, and P is erosion control factors. The R and K factors cannot be changed through management.
