| − | The '''Erodibility index''' (EI) - according to the [[USDA]] terminology - ''"is a numerical expression of the potential of a soil to [[erode]], considering the physical and chemical properties of the soil and climatic conditions where it is located. The higher the index, the greater the investment needed to maintain the sustainability of the soil resource base if intensively cropped. EI scores above 8 are equated to highly erodible land."<ref>[http://www.nrcs.usda.gov/technical/NRI/1997/summary_report/glossary.html List of USDA terminology]</ref>''
