LAND RESOURCE INVENTORY AND SOCIO-ECONOMIC STATUS OF FARM HOUSEHOLDS FOR WATERSHED PLANNING AND DEVELOPMENT KEREHALLI-2 (4D3A9E2e) MICRO WATERSHED Kasaba Hobli, Koppal Taluk and District, Karnataka ; Not Available

Abstract

Not Available ; The land resource inventory of Kerehalli-2 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, behavior and use potentials of the soils in the microwatershed. The present study covers an area of 396 ha in Koppal taluk and district, Karnataka. The climate is semiarid and categorized as drought - prone with an average annual rainfall of 662 mm, of which about 424 mm is received during south–west monsoon, 161 mm during north-east and the remaining 77 mm during the rest of the year. An area of 95 per cent is covered by soils, 150 cm).  About 9 per cent area in the microwatershed has sandy soils, 25 per cent area in the microwatershed has loamy soils and 60 per cent clayey soils at the surface.  About 78 per cent area has non-gravelly (200 mm/m) in available water capacity.  About 13 per cent area of the microwatershed has nearly level (0-1% slope) lands and 82 per cent area of the microwatershed has very gently sloping (1-3% slope) lands.  An area of about 64 per cent area is moderately (e2) eroded and about 31 per cent area is slightly (e1) eroded.  An area of about 4 per cent soils are slightly acid (pH 6.0-6.5), 30 per cent soils are neutral (pH 6.5-7.3), 33 per cent soil are slightly alkaline to strongly alkaline (pH 7.3-9.0) and 27 per cent soils are very strongly alkaline (pH >9.0) in soil reaction.  The Electrical Conductivity (EC) of the soils in the entire cultivated area of the microwatershed is dominantly 0.75%) in 55 per cent area.  Entire cultivated area of the microwatershed is high (>57 kg/ha) in available phosphorus.  An area of about 68 per cent is medium (145-337 kg/ha) and 27 per cent is high (>337 kg/ha) in available potassium.  Entire cultivated area of the microwatershed is low (1.0 ppm) in 39 per cent area of the microwatershed.  An area of about 91 per cent is sufficient (>4.5 ppm) and 4 per cent is deficient (1.0 ppm) in available manganese content.  Entire cultivated area of the microwatershed is sufficient (>0.2 ppm) in available copper content.  Entire cultivated area of the microwatershed is sufficient (>0.6 ppm) in available zinc content.  The land suitability for 31 major 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.

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. That 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.
