In RUSLE, what does 'K' represent?

In the Revised Universal Soil Loss Equation (RUSLE), 'K' specifically represents the soil erodibility factor. This parameter is crucial as it quantifies the susceptibility of a specific soil type to erosion based on its physical and chemical characteristics. The value of 'K' is influenced by various soil properties, including texture, structure, organic matter content, and permeability, all of which affect how easily soil can be detached and transported by water.

Understanding the 'K' factor is essential for erosion control and soil conservation planning, as it helps in estimating potential soil loss under specific land use and management practices. By assessing the soil erodibility, proper measures can be implemented to reduce erosion risks, making it a vital component of the RUSLE framework. The other factors mentioned in the question serve different roles within RUSLE, such as climate, vegetation, and management practices, but 'K' distinctly focuses on the inherent properties of the soil itself.
