    Question

    The Universal Soil Loss Equation (USLE) estimates average annual soil loss. The USLE is an empirically based equation, and computes sheet and rill erosion as follows: A=RKLSCP where K stands for

    A Rainfall erosivity factor Correct Answer Incorrect Answer
    B Soil erodibility factor Correct Answer Incorrect Answer
    C Slope length factor Correct Answer Incorrect Answer
    D Slope steepness factor Correct Answer Incorrect Answer
    E Support practice factor Correct Answer Incorrect Answer

    Solution

    The K factor in the Universal Soil Loss Equation measures the soil’s inherent susceptibility to erosion, influenced by its texture, structure, permeability, and organic matter. In this equation A is computed soil loss, R is the rainfall-runoff erosivity factor, L is the slope length factor, S is the slope steepness factor, C is a cover management factor, and P is a supporting practices factor.
