LAND RESOURCE INVENTORY AND SOCIO-ECONOMIC STATUS OF FARM HOUSEHOLDS FOR WATERSHED PLANNING AND DEVELOPMENT CHIKKA ALUR-1 (4D5B2A2b) MICROWATERSHED Yadgir Taluk and District, Karnataka ; Not Available

Abstract

Not Available ; The land resource inventory of Chikka Alur-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 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 591 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 383 ha in the microwatershed is covered by soils, about 141 ha by rock outcrops, about 36 ha by quarry and about 30 ha cover by others. 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 5 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.  An area of about 65 per cent is suitable for agriculture in the microwatershed.  About 17 per cent area of the microwatershed has soils that are deep to very deep (100- >150 cm), about 38 per cent soils are moderately deep (75-100 cm), whereas 10 per cent soils are moderately shallow (50-75 cm) and 200 mm/m) in available water capacity, 42 per cent soils are medium (101-150 mm/m) and 12 per cent soils are low (51-100 mm/m) and very low (0.75%) and 32 percent is medium (0.50-0.75%) in organic carbon content.  An area of about 52 percent is medium (23-57 kg/ha) and 13 percent soils are high (>57 kg/ha) in available phosphorus.  Available potassium content is high (>337 kg/ha) in an area of 57 per cent, medium (145-337 kg/ha) in about 8 per cent and low (4.5 ppm) in an area of 5 per cent and about deficient (<4.5 ppm) in about 60 per cent in the microwatershed.  Available manganese and copper are sufficient in all the soils of the microwatershed.  Available zinc content is deficient (<0.6 ppm) in the entire cultivated area of the microwatershed.  The land suitability for 29 major 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 12(2) 371(63) Guava 37(6) 14(2) Maize 49(8) 334(57) Sapota 37(6) 14(2) Bajra 51(9) 332(56) Pomegranate 37(6) 225(38) Groundnut 39(7) 69(12) Musambi 37(6) 225(38) Sunflower - 262(44) Lime 37(6) 225(38) Redgram - 326(55) Amla 51(9) 268(45) Bengal gram 211(36) 47(8) Cashew - 51(9) Cotton - 223(38) Jackfruit 37(6) 14(2) Chilli 49(8) 270(46) Jamun - 37(6) Tomato 49(8) 59(10) Custard apple 51(9) 268(45) Brinjal 49(8) 59(10) Tamarind - 37(6) Onion 49(8) 59(10) Mulberry 37(6) 14(2) Bhendi 49(8) 59(10) Marigold 49(8) 270(46) Drumstick 37(6) 225(38) Chrysanthemum 49(8) 270(46) Mango - 37(6)  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, fiber and horticulture crops.  Maintaining soil-health is vital to 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 to 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 to generate lot of biomass which would help in maintaining an ecological balance and also contribute to mitigating the climate change.
