The comparison of values of the soil erodibility factor  K (which is used in the universal equation for soil loss calculation), that were determined according to the main soil units and values of the K factor determined on the base of texture analysis, has found differences in soil texture in the range of the same main soil unit. The need of the laboratory analyses follows from the comparative analyses for the determination of K factor that is also necessary for determination of threat of soil by water erosion or for the projection of erosion control. The values of K factor that was specified according to the soil ecological units could be possible to take as orientational ones.
