Abstract/Description: | The land resource inventory of Mundrigi 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 about 411 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 89 per cent is covered by soils and 11 per cent is covered by others (Habitation and Settlements). The salient findings from the land resource inventory are summarized briefly below. The soils belong to 8 soil series and 14 soil phases (management units) and 3 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. An area of about 89 per cent is suitable for agriculture. An area of about 3 per cent of the soils are moderately shallow (50-75 cm), 62 per cent of the soils are moderately deep to deep (75-150 cm) and 23 per cent soils are very deep (>150 cm). An area of about 48 per cent area in the microwatershed has loamy soils and 40 per cent clayey soils at the surface. An area of about 57 per cent area has non-gravelly (<15% gravel) soils and 31 per cent has gravelly to very gravelly (15-60% gravel) soils. An area of about 43 per cent area is very low to low (<50-100 mm/m), 23 per cent area is medium (101-150 mm/m) and 23 per cent area is high (151-200 mm/m) in available water capacity. An area of about 10 per cent area of the microwatershed has nearly level (0-1% slope) lands and 79 per cent area of the microwatershed has very gently sloping (1- 3% slope) lands. An area of about 69 per cent area is moderately (e2) eroded and about 19 per cent area is slightly (e1) eroded. An area of about 2 per cent soils are slightly acid (pH 6.0-6.5), 74 per cent soils are neutral (pH 6.5-7.3) and 12 per cent soil are slightly alkaline (pH 7.3-7.8) in soil reaction. The Electrical Conductivity (EC) of the soils in the entire cultivated area of the microwatershed is <2 dsm-1 indicating that the soils are non-saline. Organic carbon is high (>0.75%) in 84 per cent area and medium (0.5-0.75%) in 4 per cent area of the microwatershed. Entire cultivated area of the microwatershed falls under high (>57 kg/ha) in the available phosphorus content. An area of about 12 per cent is low (<145 kg/ha), 76 per cent is medium (145-337 kg/ha) and <1 per cent is high (>337 kg/ha) in available potassium. Entire cultivated area of the microwatershed falls under low (<10 ppm) in the available sulphur content. An area of about 81 per cent is low (<0.5ppm) and 8 per cent is medium (0.5-1.0 ppm) in available boron content. An area of about 65 per cent is sufficient (>4.5 ppm) and 23 per cent is deficient (<4.5 ppm) in available iron content. Entire cultivated area of the microwatershed is sufficient (>1.0 ppm) in the available manganese content. Entire cultivated area of the microwatershed is sufficient (>0.2 ppm) in the available copper content. Entire cultivated area of the microwatershed is sufficient (>0.6 ppm) in the 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.

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. 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.
