'''Erodibility index''' or EI 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. | '''Erodibility index''' or EI 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.

Erodibility index or EI 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.
