The soil erodability factor (K) of a soil is an expression of
its inherent resistance to particle detachment (degradation)
and movement by rainfall (erosion). It is determined by the
cohesive force of the soil particles which may vary depending
on the presence or absence of plant cover, the soil’s water con-
tent and the development of its structure. In computing the K
factor in the Universal Soil Loss Equation (USLE),
