Universal Soil Loss Equation - Wikipedia
The USLE is composed of six factors to predict the long-term average annual soil loss (A). The equation includes the rainfall erosivity factor (R), the soil erodibility factor (K), the topographic factors (L and S), and the cropping management factors (C and P).
The Universal Soil Loss Equation (USLE) enables planners to predict the average rate of soil erosion for each feasible alternative combination of crop system and management practices in association with a

The Universal Soil Loss Equation (USLE) is a powerful tool that is widely used by soil conservationists in the United States and many other countries.
Using the USLE: Chances, challenges and limitations of soil ...
2019年9月1日 · We discuss model developments which use USLE-type equations as basis or side modules, but we also address recent development of the single USLE parameters (R, K, LS, C, P). Importance, aim and limitations of model validation as well as a comparison of USLE-type models with other erosion assessment tools are discussed.
Universal Soil Loss Equation: Applications & Limitations ...
The universal soil loss equation (USLE) is used for assessing the sheet and rill erosion, but not used for predicting the gully erosion. The gully erosion, caused by concentrated water flow is not counted by this equation, and as such can result greater volume of soil loss.
4.1: Universal Soil Loss Equation (USLE) - Geosciences LibreTexts
The Universal Soil Loss Equation (USLE) is a soil erosion model initially developed by the USDA-ARS, the USDA-NRCS, and Purdue University. The model is empirical, which means it was developed based on observations from experiments. It was first published in 1965 and later updated in 1978.
USLE/RUSLE have evolved over the years from data derived for varied conditions. Few if any unit plots were ever actually developed, but the con-cept was used to determine how the conditions of actual plots related to the unit plot. The USLE soil loss equation is: A = R K L S C P (8.1) where A is the computed soil loss per unit area,
