Rubber (Hevea brasiliensis) cultivation in India is confined to slope lands in the western side of Western Ghats mainly in Kerala state accounting for 90 per cent of the area. Slope lands under rubber are the most fragile and needs attention because unfavourable natural conditions can cause rapid soil erosion. Rubber-growing soils developed on different landforms in Kerala were evaluated for erodibility with respect to their inherent soil properties. Of the sixty-two soil series identified in Kerala, a total of nineteen-soil series cover nearly 70 per cent of the total area under rubber were selected. The erodibility of the soils of seven series from charnockite, five from khondalite, four from latcritc and three from granitc-gnciss landform was assessed by soil ratios and crodibility factor K using soil survey information. The results indicated soils fo Vazhoor, Vijayapuram, Kaipuzha, Anayadi, Kadambanad and Pallippadi series with high values of clay ratio and silt/clay ratio are relatively more susceptible to erosion than the other soils. Soils identified in the laterite landform showed relatively higher erodibility compared to soils of other landform. The soil erodibility factor K varies from 0.273 to 0.473, 0.353 to 0.481, 0.299 to 0.459 and 0.287 to 0.468 for soils developed on charnockite, laterite, khondalite and granite-gneiss landform respectively. The soils with higher content of intermediate particle size fractions between sand and clay showed more erodibility risk than the soils with higher clay and higher sand content conservation measures to reduce soil loss and protect existing productivity.
