RUSLE and USLE can be expressed as follows:
factor for soils is called "T value"
which stands for "Tolerable Soil Loss." It is not directly used
in RUSLE equation, but is often used along with RUSLE for conservation
planning. Soil loss tolerance (T) is the maximum amount of soil loss in
tons per acre per year, that can be tolerated and still permit a high
level of crop productivity to be sustained economically and indefinitely.
