Soil erodibility (K-factor) is an important parameter in erosion modeling, one of five factors the Revised Universal Loss Equation (RUSLE), and generally represents soil's response to rainfall run-off erosivity. The could be determined based on direct measurements soil properties mathematical calculations. In this study, K-factor was calculated a formula from RUSLE, proposed by Renard et al. (1997). All input parameters: organic carbon (SOC), structure, permeability classes were measured method, but particle size distribution - two ways sedimentation laser diffraction methods assess impact variability values rates. 107 samples Chernozems Kursk Oblast (Russia) studied. texture for most classified as silty loam both analyses.
