Accounts for the energy and intensity of rainstorms. K is the soil erodibility factor. Measures the susceptibility of a soil to erode under a standard condition. Accounts for the effect of length and steepness of slope on erosion. Estimates the soil loss ratio for each of 4 or 5 crop stage periods throughout the year, accounting for the combined effect of all the interrelated cover and management variables.
P is the support practice factor.
Accounts for the effect of conservation support practices, such as contouring, contour stripcropping, and terraces on soil erosion. Accounts for the energy and intensity of rainstorms. K is the soil erodibility factor. Measures the susceptibility of a soil to erode under a standard condition and adjusts it bi-monthly for the effects of freezing and thawing, and soil moisture. Accounts for the effect of length and steepness of slope on erosion based on 4 tables reflecting the relationship of rill to interrill erosion.
