The K-factor of the Universal soil loss equation (USLE) describes the erodibility of soils. Basically the factor depends on six soil properties: the content of silt and very fine sand, the content of sand, the organic matter content, the permeability of the soil, the aggregation of the top soil and the stone content. The method has been adapted for the DIN 19708:2005-02. The first two factors are summarized. The K-factor can now be described by the soil texture class. The DIN method is published in the documentation of AG Boden (representing the soil experts of the geological surveys of the German federal states). For the application with soil maps, the method was adapted by the Federal Institute for Geosciences and Natural Resources (BGR). The presented K-factor is based on the soil texture class, the organic content, the gravel content, the permeability of the soil and the aggregation of the top soil. The map shows the K-factor for soils in Germany based on the landuse stratified soil map of Germany at scale 1:1,000.000.
