Highly erodible soils definition
Highly erodible soils means soils (excluding vegetation) with an erodibility index (EI) from sheet and rill erosion equal to or greater than eight. The erodibility index for any soil is defined as the product of the formula RKLS/T, where K is the soil susceptibility to water erosion in the surface layer; R is the rainfall and runoff; LS is the combined effects of slope length and steepness; and T is the soil loss tolerance.
Highly erodible soils means those soils with a slope greater than 15 percent; or those soils with a K value greater than .35 and with slopes greater than 5 percent.
Highly erodible soils means very unstable soils that are generally described as Sodosols with hard setting, fine sandy loam to silty clay loam surfaces (solodics, solodised solonetz and solonetz) or soils with a dispersible layer located less than 25 cm deep or soils less than 25 cm deep.
More Definitions of Highly erodible soils
Highly erodible soils means land that is defined as highly erodible by the Sodbuster, Conservation Reserve, and Conservation Compliance parts of the Food Security Act of 1985 (P.L. 99-198) and the Food, Agriculture, Conservation, and Trade Act of 1990 (P.L. 101-624). Lists of highly erodible and potential highly erodible map units are maintained in NRCS field office technical guide.

Highly erodible soils means those soils with a K value greater than .35 and with slopes greater than 5%, and for land within the critical area, slopes greater than 15%.
Highly erodible soils means soils (excluding vegetation) with an erodibility index (EI) from sheet and rill erosion equal to or greater than eight. The erodibility index for any soil is defined as the product of the formula RKLS/T, as defined by the "Food Security Act (F.S.A.) Manual" of August, 1988 in the "Field Office Technical Guide" of the U.S. Department of Agriculture Soil Natural Resource Conservation Service, where K is the soil susceptibility to water erosion in the
