Table 5. USLE Variables and their Definitions. <br /> Variable Definition <br /> R Climatic erosivity factor due to precipitation <br /> K Soil erodibility under a standard condition <br /> LS Slope length and steepness factor <br /> C Cover management/land use <br /> P Support practices factor <br /> The Division finds Trapper's selected USLE variables reasonable. The variables are similar to <br /> those found acceptable by the Division for Trapper's previous bond releases. The lands in SL 19 <br /> are similar to lands in previous bond releases. Trapper's basis for selecting each variable and the <br /> Divisions review of each variable is presented in the table below: <br /> Table 6.
