The correct answer is
Soil Erodability Factor
USLE Equation: Defining the 'K' Factor
The Universal Soil Loss Equation (USLE) is a model used to predict the amount of soil erosion. The standard form of the equation is:
$ A = R \times K \times LS \times C \times P $
In this equation:
- A = Average annual soil loss (e.g., tons per acre per year)
- R = Rainfall-Runoff Erosivity Factor
- K = Soil Erodability Factor
- LS = Combined Slope Length and Slope Steepness Factor
- C = Cover Management Factor
- P = Support Practice Factor
The 'K' factor specifically measures the soil's susceptibility to erosion. It depends on soil properties like texture, structure, organic matter content, and permeability. A higher 'K' value indicates that the soil is more easily eroded.
Therefore, the alphabet 'K' in the USLE formula represents the Soil Erodability Factor.
