The land resource inventory of Babulgaon-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 and use potentials of the soils in the microwartershed. The present study covers an area of 404 ha in Babulgaon-2 microwatershed in Humnabad taluk of Bidar district, Karnataka. The climate is semiarid and categorized as drought- prone with an average annual rainfall of 811 mm, of which about 609 mm is received during south–west monsoon, 109 mm during north-east and the remaining 93 mm during the rest of the year. An area of about 97 per cent is covered by soils and three per cent is covered by waterbodies, settlements and others. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 9 soil series and 34 soil phases (management units) and 4 land use classes. The length of crop growing period is about 150 days starting from the 1st week of June to 2nd 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 250 m grid interval. Land suitability for growing major agricultural and horticultural crops were assessed and maps showing degree of suitability along with constraints were generated. Entire area is suitable for agriculture. About 87 per cent of the soils are moderately deep to deep and very deep (75- >150 cm) and 10 per cent are shallow (25-50 cm) soils. An area of 75 per cent has clayey soils at the surface and 22 per cent soils are loamy at the surface. About 80 per cent of the area has non-gravelly soils and 17 per cent gravelly to very gravelly (15-60% gravel) soils. About 18 per cent of the area are very high (>200mm/m), 32 per cent medium (100- 150 mm/m) and 47 per cent low (50-100 mm/m) to very low ( Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
