The land resource inventory of Kavalur East-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 370 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south –west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. An area of 99 per cent is covered by soils and one per cent is by water bodies. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 7 soil series and 10 soil phases (management units) and 3 Land management units. The length of crop growing period is 150 cm). Entire area has clayey soils at the surface. About 68 per cent area has non-gravelly (200 mm/m) in available water capacity. About 9 per cent area has nearly level (0-1%) lands and 90 per cent area has very gently sloping (1-3%) lands. About 9 per cent area is slight eroded (e1) and 90 per cent area is moderately eroded (e2) lands. Entire area is strongly alkaline (pH 8.4-9.0) to very strongly alkaline (pH >9.0) in soil reaction. Entire area has non saline ( Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
