Abstract: A detailed study was conducted to assess the land capability and land suitability of Kalmali North-1 micro watershed. The micro watershed is located in Lingasugur taluk, Raichur district, Karnataka, India. Initially, a detailed land resource survey was carried out at 1:8000 scale to derive soil phase units based on land surface and profile characters. Six soil series were identified and further mapped into seven soil phase units. The soil phase unit “FTPmB2†covered maximum area of 143 ha (56.97%) with gently sloping (1-3%) and moderate erosion in Kalmali North-1 micro watershed. Land capability classes in the study area were IIes, IIIes and IVes with limitations of soil erosion, texture, soil drainage, soil fertility and topography. Suitability for agricultural crops showed that an area of 172 ha (68.78%) was highly suitable (S1) for growing Paddy, Cotton, Sorghum and Green gram and about 71 ha (21.81%) was moderately suitable (S2) for Sorghum and Green gram with limitation to topography and texture. Soil phase unit wise crop plan with suitable interventions for field crops, horticultural crops, vegetables, millets and pulses were developed, which by implementing increases productivity and farm income.
