The land resource inventory of Bachanahalli-2 microwatershed was conducted using village cadastral maps and IRS satellite imagery on 1:7920 scale. The false colour composites of IRS imagery were interpreted for physiography and these physiographic delineations were used as base for mapping soils. The soils were studied in several transects and a soil map was prepared with phases of soil series as mapping units. Random checks were made all over the area outside the transects to confirm and validate the soil map unit boundaries. The soil map shows the geographic distribution and extent, characteristics, classification, behavior and use potentials of the soils in the microwatershed. The present study covers an area of 39 ha out of total area of 639 ha in Gundlupet Taluk, Chamarajanagar District Karnataka. The remaining area of about 600 ha is under Berambadi State Forest. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 734 mm, of which about 254 mm is received during the south –west monsoon, 26 8mm during north-east and the remaining 212 mm during the rest of the year. An area of about 6 per cent is covered by soils, 94 per cent by forests and 150 cm) soils. About 4 per cent area has loamy soils and 2 per cent area has clayey soils at the surface. About 5 per cent of the area has non-gravelly soils and 1 per cent gravelly soils (15- 35 % gravel) soils. About 4 per cent area has low (51-100 mm/m) and 2 per cent very high (>200 mm/m) in available water capacity. Entire area of about 6 per cent has very gently sloping (1-3%) lands. About 6 per cent area is moderately eroded (e2) lands. About 1 per cent area is slightly acidic (pH 6.0-6.5), about 5 per cent neutral (pH 6.5- 7.3) in soil reaction. The Electrical Conductivity (EC) of the soils are dominantly 0.75%). About 6 per cent area is medium (23-57 kg/ha) in available phosphorus. Major area of about 5 per cent is high (>337 kg/ha) in available potassium and a small area of about 1 per cent has medium (145-337 kg/ha) Available sulphur is low ( Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
