The land resource inventory of Kalagatahundi-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 the 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 and use potentials of the soils in the microwatershed. The present study covers an area of 417 ha in Gundlupet taluk of Chamarajanagar district, Karnataka. 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 south –west monsoon, 268 mm during north-east and the remaining 212 mm during the rest of the year. An area of about 17 per cent is covered by soils, 83 per cent by forest and others. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 4 soil series and 7 soil phases (management units) and 4 land management units. The length of crop growing period is about 150 days starting from the 3rd week of June to 3rd week of November. From the master soil map, several interpretative and thematic maps like land capability, soil depth, surface soil texture, soil gravelliness, available water capacity, soil slope and soil erosion were generated. Soil fertility status maps for macro and micronutrients were generated based on the surface soil samples collected at every 250 m grid interval. Land suitability for growing major agricultural and horticultural crops were assessed and maps showing the degree of suitability along with constraints were generated. About 17 per cent area is suitable for agriculture. About 8 per cent of the soils are moderately deep (75-100 cm) to very deep (>150 cm) and 10 per cent are moderately shallow (50-75 cm). About 7 per cent of the area has clayey soils at the surface and 10 per cent area has loamy soils. About 17 per cent of the area has non-gravelly soils and Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
