The land resource inventory of Wankasambar-1 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, behaviour and use potentials of the soils in the microwatershed. The present study covers an area of 408 ha in Wankasambar-1 microwatershed in Yadgir taluk and district, Karnataka. The climate is semiarid and categorized as droughtprone with an average annual rainfall of 866 mm, of which about 652 mm is received during south–west monsoon, 138 mm during north-east and the remaining 76 mm during the rest of the year. An area of about 87 per cent is covered by soils, 13 per cent by rock lands and others. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 11 soil series and 11 soil phases (management units) and 8 land management units. The length of crop growing period is 120-150 days starting from the 1st week of June to 4th week of October. 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 320 m grid interval. Land suitability for growing 26 major agricultural and horticultural crops were assessed and maps showing the degree of suitability along with constraints were generated. Entire land area of the microwatershed is suitable for agriculture. About 10 per cent soils are shallow (25-50 cm), 27 per cent soils are moderately shallow (50-75 cm), 18 per cent are moderately deep (75-100 cm) and about 31 per cent soils are deep (100-150 cm) to very deep (>150 cm) soils. About 12 per cent of the area has clayey soils, 52 per cent loamy soils and 23 per cent sandy soils at the surface. Entire area of about 87 per cent has non-gravelly. About 15 per cent of the area has soils that are very high (>200 mm/m) in available water capacity, 31 per cent medium (101-150 mm/m), 27 per cent low (51-100 mm/m) and about 14 per cent very low ( Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
