The land resource inventory of Hosur-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 boundries. The soil map shows the geographic distribution and extent, characterstics, classification and use potentials of the soils in the microwartershed. The present study covers an area of 487 ha in Shirahatti taluk of Gadag district, Karnataka. The climate is semiarid and categorized as drought prone with an average annual rainfall of 633 mm of which about 363 mm is received during south –west monsoon, 165 mm during north-east and the remaining 105 mm during the rest of the year. An area of about 96 per cent is covered by soils, four per cent by waterbodies, settlements and others. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 6 soil series and 13 soil phases (management units) and 5 land management units. The length of crop growing period is about 150 days starting from the 3rd week of June to 1st 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. About 98 per cent area is suitable for agriculture. About 19 per cent of the soils are deep (100 - 150 cm) to moderately deep (75-100 cm), 76 per cent are moderately shallow to shallow (25-75 cm) and about 3 per cent are very shallow (9.0). The Electrical Conductivity (EC) of the soils are dominantly 20 ppm). Available boron is low (0.5 ppm) in about 89 per cent area, medium (0.5-1.0 ppm) in 8 per cent area and high (>1.0 ppm) in 1 per cent area. Available iron is deficient in about 3 per cent area and sufficient in 95 per cent area. Available manganese and copper are sufficient in all the soils. Available zinc is deficient ( Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
