Ravindra Naik M. [2] | Anilkumar K. S. [2]

Abstract: Application Of RS Tools For land resources of the watershed was carried out by using cadastral map (110 000 scale) as base. Apart from the cadastral map, remote sensing data products from IRS LISS IV (5.8 m resolution) and Cartosat-1 (2.5 m resolution) were used to identify the landforms and other surface features of Kannur watershed, Chamarajnagar District, Karnataka belonging to Southern Dry Zone. Eight soil profiles representing the study area were selected based on the topography from various physiographic units identified in the area by field survey. Depth of the soils ranged from moderately deep to very deep, colour varied from reddish brown to dark red in uplands and yellowish brown to dark grey in lowland. The texture of the soils was from sandy clay loam to sandy clay. The common structure was weak, fine, sub angular blocky in surface horizons, while moderate medium sub-angular blocky in subsoil. Soil reaction varied from slightly acidic to strongly alkaline (6.2 to 8.7). The organic carbon and CEC of the soil varied from low to medium, 0.2 to 0.65 per cent and 5.0 to 33.9 cmol (p+) kg-1 respectively. The upland physiographic units were low in CEC values than midlands and lowlands owing to their low clay content, low organic matter and predominance of 11 type of clay minerals, whereas lowlands exhibited moderate CEC values due to higher clay content. The available nitrogen, phosphorus and potassium were low, low to medium and medium respectively.
