Description: Soil erodibility factor, also known as K factor, is one of the 5 inputs to the Universal Soil Loss Equation. Soil erodibility factor quantifies the susceptibility of soil particles to detachment and movement by water. For more information on how soil erodibilty factor is calculated see the National Soil Survey Handbook.Erodibility factor is a value between 0 and 1. Divide each raw pixel integer value by one hundred to find its erodibility factor value. For example, a raw pixel value of 34 represents an erodibility factor of 0.34.The Universal Soil Loss Equation is a mathematical model commonly used to estimate soil erosion rates. Originally designed for the management and conservation of farmland soils, the USLE is now used for a variety of other projects such as managing non-point pollution and sediment load in streams.In the United States, the equation is frequently used by federal agencies. For example federal regulations require that the Department of Agriculture identify highly erodible land based on the Universal Soil Loss Equation and its derivative models.
