The land resource inventory of Hanumantharayanagudda-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 131 ha out of total area of 668 ha in Gundlupet Taluk, Chamarajanagar District Karnataka. The remaining area of about 509 ha is under 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, 268 mm during north-east and the remaining 212 mm during the rest of the year. An area of about 20 per cent is covered by soils, 76 per cent by forests and 4 per cent by others. 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 6 land management units. The length of Land growing period is 150 days and starts from 3rdweek of June to 3rdweek 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 27 major agricultural and horticultural Lands were assessed and maps showing the degree of suitability along with constraints were generated. Entire area is suitable for agriculture. About 3 per cent area of the soils are moderately shallow (50-75 cm), 2 per cent moderately deep (75-100 cm), 1 per cent deep (100-150 cm) and 14 per cent very deep (>150 cm) soils. About 2 per cent area has loamy soils, 2 per cent sandy and 16 per cent area has clayey soils at the surface. About 16 per cent of the area has non-gravelly soils ( Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
