The soil erodibility factor according to the USLE method was calculated for selected Polish soils. Data from 10 experimental plots of different soils in black fallow a terrain slope of 10% and in sprinkling conditions, were used for the study. The comparison of real data and data obtained form equations given by Wischmeier and Smith, as well as by Wiliams, revealed considerable differences in KUSLE values of the investigated soils. The statistical investigations were conducted to find the best fitting between observed and numerically predicted KUSLE values. The highest correlation (R=0.65) revealed the pair of MUSLE and ln(Kd /Kw) variables, where Kd represents real KUSLE values, while Kw KUSLE was calculated with Williams equation. The non-linear logarithmic regression model has shown the best fit, reaching the regression of R=0.77 between variables ln(Kd /Kw), MUSLE and outflow coefficient.
