LAND RESOURCE INVENTORY AND SOCIO-ECONOMIC STATUS OF FARM HOUSEHOLDS FOR WATERSHED PLANNING AND DEVELOPMENT BANDEHALLI-1 (4D2D6O2b) MICROWATERSHED Sydhapur Hobli, Yadgir Taluk and District, Karnataka ; Not Available

Abstract

Not Available ; The land resource inventory of Bandehalli-1 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, behaviour and use potentials of the soils in the microwatersheds. The present study covers an area of 699 ha in Bandehalli-1 microwatershed in Yadgir taluk and district, Karnataka. The climate is semiarid and categorized as droughtprone 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 about 95 per cent is covered by soils, 5 per cent by habitation and water bodies. The salient findings from the land resource inventory are summarized briefly below.  The soils belong to 9 soil series and 11 soil phases (management units) and 6 land use classes.  The length of crop growing period is 120-150 days starting from the 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 26 major agricultural and horticultural crops were assessed and maps showing the degree of suitability along with constraints were generated.  Entire land area of the microwatershed is suitable for agriculture.  About 2 per cent soils are very shallow (200 mm/m) in available water capacity, 27 per cent medium (101-150 mm/m), 14 per cent low (51-100 mm/m) and about 32 per cent very low (0.75%) in organic carbon.  An area of 18 per cent has soils that are low (57 kg/ha) in available phosphorus.  About 5 per cent low (337 kg/ha) in available potassium.  Available sulphur is low (20 ppm) in about 9 per cent area of the microwatershed.  Available boron is low (1.0 ppm) in about 14 per cent area of the microwatershed.  Available iron are sufficient (>4.5 ppm) in all the soils of the microwatershed.  Available manganese is sufficient in all the soils of the microwatershed.  Available copper is sufficient in a maximum area of 95 per cent and deficient in <1 per cent area.  Major area of the microwatershed is deficient (<0.6 ppm) in available zinc and a small area of 1 per cent is sufficient in available zinc.  The land suitability for 26 major agricultural and horticultural crops grown in the microwatershed was 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 Bandehalli-1 microwatershed Crop Suitability Area in ha (%) Crop Suitability Area in ha (%) Highly suitable (S1) Moderately suitable (S2) Highly suitable (S1) Moderately suitable (S2) Sorghum 152 (22) 239 (34) Sapota - 97 (14) Maize - 341 (49) Guava - 97 (14) Red gram - 392 (56) Pomegranate - 392 (56) Bajra - 439 (63) Jackfruit - 97 (14) Ground nut - 97 (14) Jamun - 152 (22) Sunflower 152 (22) 240 (34) Musambi 47 (7) 392 (56) Cotton 152 (22) 142 (20) Lime 47 (7) 392 (56) Bengalgram 152 (22) 142 (20) Cashew - - Chilli - 391 (56) Custard apple 213 (31) 178 (26) Tomato - 97 (14) Amla - 391 (56) Drumstick - 392 (56) Tamarind - 152 (22) Mulberry - 97 (14) Marigold - 391 (56) Mango - 81 (12) Chrysanthemum - 391 (56) Apart from the individual crop suitability, a proposed crop plan has been prepared for the 6 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 that helps in maintaining the ecological balance in the microwatershed  Maintaining soil-health is vital for crop production and conserve 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 supplementing the farm income, provide fodder and fuel, and generate lot of biomass which in turn would help in maintaining the ecological balance and contribute to mitigating the climate change.
