Abstract: A study was undertaken to evaluate four soil series belonging to Vellamadai village of Coimbatoredistrict, Tamil Nadu for sustainable land use planning. Four soil series were tentatively identified and mapped into seven mapping units using GIS technique. These mapping units were grouped in to land capability class III and IV with limitations of soil texture and cation exchange capacity. Soil-site suitability evaluation for sorghum, cotton, sugarcane, maize and pearlmillet showed that clay soils were highly suitable (S1) for Sugarcane, moderately suitable (S2) for cotton, sorghum, sugarcane and pearl millet, marginally suitable (S3) for sorghum and maize. The loamy sand soils were moderately suitable (S2) for pearl millet, marginally suitable (S3) for sorghum and not suitable for cotton, sugarcane and maize.
Keywords: land evaluation, GIS, soil suitability
