LAND RESOURCE INVENTORY AND SOCIO-ECONOMIC STATUS OF FARM HOUSEHOLDS FOR WATERSHED PLANNING AND DEVELOPMENT WANKASAMBAR-3 (4D2D6M2a) MICROWATERSHED Balichakra Hobli, Yadgir Taluk and District, Karnataka ; Not Available
Not Available ; The land resource inventory of Wankasambar-3 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 583ha 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 577 ha (98%) in the microwatershed is covered by soils and 150 cm) and 13 per cent soils are moderately shallow (50-75 cm). About 47 per cent area in the microwatershed has loamy soils, 40 per cent clayey soils and 13 per cent are sandy at the surface. Entire area of the microwatershed is non gravelly (200 mm/m) in available water capacity. Entire area in the microwatershed has very gently sloping (1-3% slope) lands. An area of about 1 per cent are slightly (e1) eroded, 91 per cent are moderately (e2) eroded and 7 per cent area severely (e3) eroded. An area of about 1 per cent soils are moderately acid (pH 5.5-6.0), 10 per cent soils are slightly acid (pH 6.0-6.5), 26 per cent soils are neutral (pH 6.5-7.3), 20 per cent soils are slightly alkaline (pH 7.3-7.8), 23 per cent soils are moderately alkaline (pH 7.8 - 8.4), 17 per cent soils are strongly alkaline (pH 8.4-9.0) and 2 per cent soils are very strongly alkaline. The Electrical Conductivity (EC) of the soils in the entire area of the microwatershed is dominantly 0.75%) in organic carbon. About34 per cent area is low (57 kg/ha) in available phosphorus. About 24 per cent is low (20 ppm) in 7 per cent area of the microwatershed. Available boron is low (1.0 ppm) in 23 per cent area of the microwatershed. Available iron is sufficient (>4.5 ppm) in all the soils of the microwatershed. Available manganese and copper are sufficient in all the soils of the microwatershed. Available zinc is deficient (<0.6 ppm) in the entire area of the microwatershed. The land suitability for 26 major agricultural and horticultural crops grown in the microwatershed were assessed and the areas that are highly suitable (S1) and moderately suitable (S2) are given below. It is however to be noted that a given soil may be suitable for various crops but what specific crop to be grown may be decided by the farmer looking to his capacity to invest on various inputs, marketing infrastructure, market price and finally the demand and supply position. Land suitability for various crops in the Microwatershed Crop Suitability Area in ha (%) Crop Suitability Area in ha (%) Highly suitable (S1) Moderately suitable (S2) Highly suitable (S1) Moderately suitable (S2) Sorghum 97(17) 432(75) Sapota - 114(20) Maize 97(17) 55(9) Pomegranate - 491(85) Bajra 97(17) 461(79) Musambi - 491(85) Groundnut - 169(29) Lime - 491(85) Sunflower - 474(82) Amla 97(17) 432(74) Redgram - 491(84) Cashew - 65(11) Bengal gram 38 (7) 491(84) Jackfruit - 97(17) Cotton 6(1) 523(90) Jamun - 187(32) Chilli - 546(94) Custard apple 97(17) 432(74) Tomato 97(17) 72(12) Tamarind - 187(32) Drumstick - 491(85) Mulberry - 97(17) Mango - - Marigold - 546(94) Guava - 114(20) Chrysanthemum - 546(94) Apart from the individual crop suitability, a proposed crop plan has been prepared for the identified LMUs by considering only the highly and moderately suitable lands for different crops and cropping systems with food, fodder, fibre and other horticulture crops. Maintaining soil-health is vital for crop production and conserves soil and land resource base for maintaining ecological balance and to mitigate climate change. For this, several ameliorative measures have been suggested for these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation treatment plan has been prepared that would help in identifying the sites to be treated and also the type of structures required. As part of the greening programme, several tree species have been suggested to be planted in marginal and submarginal lands, field bunds and also in the hillocks, mounds and ridges. This would help in not only supplementing the farm income but also provide fodder and fuel and generate lot of biomass which would help in maintaining an ecological balance and also contribute to mitigating the climate change.
