Abstract/Description: | The land resource inventory of Chennahalu-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 548 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 about 96 per cent is covered by soil, <1 per cent by rock outcrops and 4 per cent by habitation and water body. The salient findings from the land resource inventory are summarized briefly below The soils belong to 14 soil series and 20 soil phases (management units) and 9 land management units. The length of crop growing period is <90 days and starts from 2nd week of August to 2nd week of November. 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 31 major agricultural and horticultural crops were assessed and maps showing the degree of suitability along with constraints were generated. Entire area is suitable for agriculture. About 7 per cent of the soils are shallow (25-50 cm), 10 per cent is moderately shallow (50-75 cm), 33 per cent is moderately deep (75- 100 cm) and 46 per cent is deep to very deep (100 to >150 cm) soils. About 3 per cent sandy (loamy sand), 71 per cent loamy (sandy loam and sandy clay loam) and 22 per cent has clayey (sandy clay and clay) soils at the surface. About 33 per cent of the area has non-gravelly (<15%) soils, 60 per cent has gravelly (15-35 %) and 3 per cent has very gravelly (35-60 %) soils. With respect to available water capacity 16 per cent of the area has very low (<50 mm/m), 42 per cent low (51-100 mm/m), 17 per cent medium (101-150 mm/m), 4 per cent high (151-200 mm/m) and 16 per cent very high (>200 mm/m) in available water capacity. An area of about 11 per cent is nearly level (0-1%) and 85 per cent is very gently sloping (1-3%) lands. An area of about 29 per cent is slightly eroded (e1) and 67 per cent is moderately eroded (e2) lands. An area of about 29 per cent is moderately acid (pH 5.5-6.0), 35 per cent is slightly acid (pH 6.0-6.5), 20 per cent is neutral (pH 6.5-7.3), 10 per cent is slightly alkaline (pH 7.3-7.8) and <1 per cent is strongly alkaline (pH 8.4-9.0) in reaction. The Electrical Conductivity (EC) of the soils are <2 dSm-1 indicating that the soils are non saline. Organic carbon is medium (0.5-0.75%) in 59 per cent and high (>0.75%) in 37 per cent area of the soils. Available phosphorus is medium (23-57 kg/ha) in 10 per cent and high (>57 kg/ha) in 85 per cent area of the soils. Available potassium is medium (145-337 kg/ha) in 37 per cent and high (>337 kg/ha) in 58 per cent area of the soils. Available sulphur is medium (10-20 ppm) in 81 per cent and high (>20 ppm) in 14 per cent area of the soils. Available boron is low (<0.5 ppm) in 69 per cent and medium (0.5-1.0) in 26 per cent area of the microwatershed. Available iron is deficient (<4.5 ppm) in 3 per cent and sufficient (>4.5 ppm) in 93 per cent area of the microwatershed. Available zinc is deficient (<0.6 ppm) in 65 per cent and sufficient (>0.6 ppm) in 31 per cent area of the microwatershed. Available manganese and copper are sufficient in the entire area of the microwatershed. The land suitability for 31 major agricultural and horticultural crops grown in the microwatershed was assessed and the areas that are highly suitable (class S1) and moderately suitable (class 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.

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 to these problematic soils like saline/alkali, highly eroded, sandy soils etc., Soil and water conservation and drainage line 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.
