The land resource inventory of Ajalapur 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 879 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 849 ha in the microwatershed is covered by soils, 3 ha by rock outcrops and 27 ha by others (habitation and water bodies). The salient findings from the land resource inventory are summarized briefly below. The soils belong to 9 soil series and 14 soil phases (management units) and 6 land management units. 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 320 m grid interval. Land suitability for growing 29 major agricultural and horticultural crops was assessed and maps showing the degree of suitability along with constraints were generated. About 849 ha area in the microwatershed is suitable for agriculture. About 35 per cent area of the microwatershed has soils that are deep (100 -150 cm), 54 per cent has moderately deep (75-100 cm),3 per cent has moderately shallow (50-75 cm) and 5 per cent has shallow (25-50 cm).. About 21 per cent area in the microwatershed has sandy soils, 74 per cent area in the microwatershed has loamy soils and Watershed Development Department, Government of Karnataka (World Bank Funded) Sujala –III Project |
