Abstract

The influence of physical and chemical properties on the erodibility of some soils of the Malwa plateau in Madhya Pradesh was investigated. Erosion ratio was negatively correlated with clay/(silt + sand) ratio, percentage of water stable aggregates larger than 0.25 mm, percentage of exchangeable calcium in the soil, and silica-iron oxide ratio. Highly significant positive correlations were obtained between erosion ratio and the percentage of volume expansion, and between erosion ratio and moisture equivalent. A linear regression equation relating the erosion ratio to clay/(silt + sand) ratio, moisture equivalent, and the percentage of calcium carbonate is described to estimate erosion ratio in these and similar soils.
