Abstract: A case study was undertaken to characterize and map the soils of a Timanhal micro-watershed in Northern dry zone of Karnataka in order to assess their land capability, productivity potentials and suitability for crops. The soil survey of Timanhal micro-watershed, Kushtagi Taluk, Koppal District was conducted using toposheet as base and superimposing over 1:20,000 scale satellite imagery as well as Google Earth images. Seven soils and/or their phases were identified and studied for their morphological, physical and chemical properties in the micro-watershed. The identified soils are mapped into ten land units. The dominant soils were gently sloping lands. The soils were shallow to deep (42-136 cm), reddish brown to grey (2.5YR 3/4-10YR 5/2), sandy clay loam to clay, neutral to alkaline (6.61-9.53), low to medium in organic carbon (1.3-6.8 g/kg), low to high in CEC (10.5-53.4 cmol(p+)/kg), high base saturated soils, low in available nitrogen (90-250 kg/ha), low to medium in available phosphorus (14–89 kg/ha), low to high in available potassium (97-331 kg/ha) and low in available sulphur (6.4-18.4 mg/kg), the micro nutrients, available copper, available iron, available manganese content were sufficient to adequate and available zinc content was deficit to sufficient. Land capability classification showed that majority of soils belonged to class III and IV lands with limitations of erosion, wetness and soil properties. Land suitability evaluation for pearl millet, maize and groundnut showed that soils were marginally suitable (S3) and red gram, cotton and mango were not suitable (N). The actual productivity of soils was average to extremely poor. However the potential productivity of soils is good to poor. The coefficient of improvement is 1.95 to 1.97.
