What does the term 'C' in the RUSLE equation refer to?

The term 'C' in the RUSLE (Revised Universal Soil Loss Equation) refers to the Cover Management Factor. This factor is crucial in determining the potential for soil erosion as it quantifies the effect of soil cover on erosion rates. The cover includes both the vegetation and the surface residues, and it plays a significant role in reducing soil erosion by protecting the soil surface from raindrop impact and reducing runoff speed.

The Cover Management Factor accounts for the type and amount of vegetation or ground cover present, which greatly influences how effectively it can intercept rainfall, promote infiltration, and stabilize soil. For instance, a well-vegetated area will have a lower value for the 'C' factor, indicating better protection against erosion. Understanding the 'C' factor and its implications is essential for effective soil conservation practices and management strategies aimed at minimizing erosion in agricultural and disturbed lands.
