The land resource inventory of Ramapura-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, behavior and use potentials of the soils in the microwatershed. The present study covers an area of 577 ha in Yadgir taluk & district, Karnataka. The climate is semiarid and categorized as drought-prone 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 549 ha in the microwatershed is covered by soils, 0.05 ha by rock outcrops and about 28 ha by others (habitation and water bodies). The salient findings from the land resource inventory are summarized briefly below. The soils belong to 12 soil series and 26 soil phases (management units) and 6 land use class. The length of crop growing period is about 120-150 days starting from 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 250 m grid interval. Land suitability for growing 26 major agricultural and horticultural crops was assessed and maps showing the degree of suitability along with constraints were generated. Entire area in the microwatershed is suitable for agriculture. About 59 per cent area of the microwatershed has soils that are moderately deep to very deep (75 - >150 cm) and 36 per cent soils are shallow to moderately shallow (25-75 cm). About 6 per cent area in the microwatershed has sandy soils, 26 per cent of loamy soils and 64 per cent clayey soils at the surface. About 63 per cent area in the microwatershed is non gravelly (200 mm/m) in available water capacity, 2 per cent is medium (101-150 mm/m), 32 per cent area is low (51-100 mm/m) and 4 per cent area is very low (9.0). The Electrical Conductivity (EC) of the soils in the entire area of the microwatershed is dominantly 57 kg/ha). About 70 per cent is medium (145-337 kg/ha) in available potassium and 25 per cent is high (>337 kg/ha). Available sulphur is low ( Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
