Question Statement:
In the Universal Soil Loss Equation (USLE) $A = R \cdot K \cdot L \cdot S \cdot C \cdot P$, which of the following statements is/are CORRECT?
Options:
- (A) $R$ is the rainfall-runoff erosivity factor determined by the product of total kinetic energy and maximum 30-minute intensity
- (B) $K$ is the soil erodibility factor evaluated on a standard fallow plot of $22.13\text{ m}$ length on a $9\%$ slope
- (C) $P$ factor equals 1.0 when contour bunding is implemented on steep slopes
- (D) $C$ factor represents the cropping-management ratio relative to continuous bare fallow
