Abstract/Description: | The land resource inventory of Bettageri-1microwatershedwas 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 391ha in Koppaltalukand 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, 161mm during north-east and the remaining 77 mm during the rest of the year. An area of about 91 per cent is covered by soils, 9 per cent byhabitation and water bodies. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 8soil series and 9soil phases (management units) and 7 land use classes. 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 250 m grid interval. Land suitability for growing 24 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. About42per cent of the soils areshallowto moderately shallow (25-75 cm)and49per cent area are moderately deep to deep(75-150 cm). About 46 per cent areahas loamy soils and 45 per cent area has clayey soils at the surface. About 5 per cent of the area has non-gravelly soils, 44per cent gravelly soils (15-35 % gravel) and 41 per cent very gravelly (35- 60% gravel) soils. About 63 per cent area has verylow to low (<50-100 mm/m), 23 per cent medium (101-150 mm/m) and 5per cent very high (>200mm/m) in available water capacity. Entire area has very gently sloping (1-3%) lands. About 33per cent area is slightly eroded and about 58 per cent area ismoderately eroded (e2) lands. About 6 per cent area is slightly acidic (pH 6.0-6.5) about 18 per cent neutral, 67 per cent area is slightly alkaline (pH 8.4 to 9.0)to very strongly alkaline (pH>9.0)in soil reaction. The Electrical Conductivity (EC) of the soils are dominantly <2 dsm-1indicating that the soils are non-saline. Organic carbon islow (<0.5%) in about 20per cent,39 per cent of the soils are medium (0.5-0.75%)and32per cent of the soils are high (>0.75%) in organic carbon. About 6 per cent area is low (<23 kg/ha), medium (23-57 kg/ha) in major area of 71 per cent and 14 per cent area is high (>57 kg/ha) available phosphorus. Major area of about 86 per centismedium (145-337 kg/ha) in available potassium and a small area of about 5 per cent has high (>337 kg/ha) in available potassium. Available sulphur is low (<10 ppm) in 66 per cent area, medium (10-20 ppm) in about 24per cent area and about <1per cent area is high (>20 ppm). Available boron is low (0.5 ppm) in about 60 per cent area and medium (0.5-1.0 ppm) in 31per cent area. Available iron is sufficient (>4.5 ppm)in40 per cent area and deficient (<4.5 ppm) in about 51 per cent area. Available zinc is deficient (<0.6 ppm) inan area of about 36 per cent and sufficient in 55per cent area. Available manganeseand copper are sufficient in all the soils. The land suitability for 25 major crops grown in the microwatershedwere 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 20 (5) 143 (37) Guava - 101 (26) Maize - 142 (36) Jackfruit - 101 (26) Bajra 88 (23) 54 (14) Jamun - 108 (28) Groundnut - 142 (36) Musambi 20 (5) 101 (26) Sunflower 20 (5) 101 (26) Lime 20 (5) 101 (26) Chilli - 142 (36) Cashew - 160 (41) Tomato - 142 (36) Custard apple 108 (28) 127 (32) Drumstick - 121 (31) Amla 88 (23) 147 (37) Mulberry - 193 (49) Tamarind - 20 (5) Mango - - Marigold - 163 (42) Sapota - 101 (26) Chrysanthemum - 163 (42) Pomegranate - 121 (31) Jasmine - 143 (37) Crossandra - 145 (36) Apart from the individual crop suitability, a proposed crop plan has been prepared for the7identified LUCs 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 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. 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.
