LAND RESOURCE INVENTORY AND SOCIO-ECONOMIC STATUS OF FARM HOUSEHOLDS FOR WATERSHED PLANNING AND DEVELOPMENT NAZARAPUR-1 (4D5B6D2e) MICROWATERSHED Gurumitkal Hobli, Yadgir Taluk and District, Karnataka

Abstract

The land resource inventory of Nazarapur-1Microwatershed 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 539 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 404 ha in the microwatershed is covered by soils, 123 ha by rock outcrops and 12 ha by others (habitation and water body). The salient findings from the land resource inventory are summarized briefly below.  The soils belong to 5 soil series and 9 soil phases (management units) and 4 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.  Entire area in the microwatershed is suitable for agriculture.  About 6 per cent area is very shallow (<25 cm), 39 per cent area is shallow (25- 50 cm), 27 per cent area is deep (100-150 cm) and 3 per cent area is very deep (>150 cm) in the microwatershed.  About 10 per cent area in the microwatershed has sandy soils, 51 per cent loamy soils and 14 per cent clayey soils at the surface  An area of 30 per cent is non gravelly (<15%) and 45 per cent gravelly (15-35%) in the microwatershed.  About 45 per cent area of the microwatershed is very low (<50 mm/m) in available water capacity, 11 per cent is low (51-100 mm/m) and 20 per cent is high (>200 mm/m) in available water capacity.  About 11 per cent area in the microwatershed has nearly level (0-1% slope) lands, 29 per cent has very gently sloping (1-3% slope) and 35 per cent has gently sloping (3-5%) lands.  An area of about 64 per cent is moderately (e2) eroded and 11 per cent area is slightly (e1) eroded.  An area of about 3 per cent area is slightly acid (pH 6.0-6.5) in soil reaction, 8 per cent area is neutral (pH 6.5-7.3) and 63 per cent soils is slightly to moderately alkaline (pH 7.3-8.4)  The Electrical Conductivity (EC) of entire soils of the microwatershed is dominantly <2 dsm-1indicating that the soils are non-saline.  About 29 per cent of the soils are medium (0.5-0.75%) in organic carbon and 46 per cent high (>0.75%).  42 per cent area is medium (23-57 kg/ha)in available phosphorus and 33 per cent area is high (> 57 kg/ha).  About 63 per cent is medium (145-337 kg/ha) in available potassium and 12 per cent is high (>337 kg/ha).  Available sulphur is medium (10-20 ppm) in the entire area of the microwatershed  Available boron is medium (0.5-1.0 ppm) in the entire area of the microwatershed  Available iron is sufficient (>4.5 ppm) in the entire area of the microwatershed.  Available manganese and copper are sufficient in all the soils of the microwatershed.  Available zinc is deficient (<0.6 ppm) in 67 per cent and sufficient (>0.6 ppm) in 8 per cent 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 106 (20) - Guava - - Maize - 106 (20) Sapota - - Bajra - 106 (20) Pomegranate - 106 (20) Groundnut - - Musambi 106 (20) - Sunflower 106 (20) - Lime 106 (20) - Redgram - 105 (20) Amla 19 (3) 87 (16) Bengal gram 106 (20) - Cashew - - Cotton 106 (20) - Jackfruit - - Chilli - 105 (20) Jamun - 106 (20) Tomato - 87 (16) Custard apple 106 (20) - Brinjal 87 (16) 19 (3) Tamarind - - Onion 60 (11) - Mulberry - - Bhendi 87 (16) 19 (3) Marigold - 105 (20) Drumstick - 105 (20) Chrysanthemum - 105 (20) Mango - 87 (16)  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 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 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.
