Abstract/Description: | The land resource inventory of Shivapura-1 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 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 boundries. The soil map shows the geographic distribution and extent, characterstics, classification and use potentials of the soils in the microwartershed. The present study covers an area of 596 ha in Gundlupet taluk of Chamarajanagar district, Karnataka. The climate is semiarid and categorized as drought prone with an average annual rainfall of 734 mm of which about 254 mm is received during south –west monsoon, 268 mm during north-east and the remaining 212 mm during the rest of the year. An area of about 96 per cent is covered by soils, four per cent by others. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 8 soil series and 24 soil phases (management units) and 7 land management units. The length of crop growing period is about 150 days starting from the 3rd week of June to 1st 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 250 m grid interval. Land suitability for growing major agricultural and horticultural crops were assessed and maps showing the degree of suitability along with constraints were generated. About 96 per cent area is suitable for agriculture. About 8 per cent of the soils are moderately deep (75-100 cm) to very deep (>150 cm) and 87 per cent are shallow to moderately shallow (25-75 cm). About 34 per cent of the area has clayey soils at the surface, 40 per cent loamy soils and 22 per cent area has sandy soils. About 7 per cent of the area has non-gravelly soils, 39 per cent gravelly soils (15-35 % gravel) and 49 per cent has very gravelly (35- 60% gravel) soils. About 88 per cent has soils that are very low (<50mm/m) to low (51-100 mm/m) in available water capacity and a small area of 7 per cent has very high (>200 mm/m) available water capacity. About 86 per cent of the area has nearly level (0-1%) to very gently sloping (1-3% slope) lands and 10 per cent is under gently sloping (3-5%) to moderately sloping (5- 10%) lands. An area of about 64 per cent has soils that are slightly eroded (e1), 22 per cent moderately eroded (e2) and 10 per cent soils are severely eroded (e3). An area of about 2 per cent has soils that are slightly acidic (pH 6.0-6.5); 14 per cent area has neutral (pH 6.5-7.3) and maximum area of about 80 per cent has soils that are slightly alkaline (pH 7.3 to 7.8) to strongly alkaline (pH 8.4 to 9.0). The Electrical Conductivity (EC) of the soils are dominantly <2 dsm-1indicating that the soils are non-saline. About 16 per cent of the soils are low (<0.5%), 64 per cent soils are medium (0.5- 0.75%) and 16 per cent of the soils are high (>0.75%) in organic carbon. About 40 per cent of the soils are low (<23 kg/ha), medium (23-57 kg/ha) in 54 per cent area and one per cent of the soils are high (>57 kg/ha) in available phosphorus. About 12 per cent of the soils are low (<145 kg/ha), medium (145-337 kg/ha) in 28 per cent area and 55 per cent of the soils are high (>337 kg/ha) in available potassium. Available sulphur is low (<10 ppm) in about 83 per cent area and medium (10-20 ppm) in about 12 per cent area. Available boron is low (0.5 ppm) in about 19 per cent area, medium (0.5-1.0 ppm) in 71 per cent area and high (>1.0 ppm) in 5 per cent area. Available iron is deficient in about 51 per cent area and sufficient in 44 per cent area. Available manganese and copper are sufficient in all the soils of the microwatershed. Available zinc is deficient (<0.6 ppm) in all the soils of the microwatershed. The land suitability for 27 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, price and finally the demand and supply position.

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 and also in the hillocks, mounds and ridges. SOCIO-ECONOMIC STATUS OF FARM HOUSEHOLDS Baseline socioeconomic characterisation is prerequisite to prepare action plan for program implementation and to assess the project performance before making any changes in the watershed development program. The baseline provides appropriate policy direction for enhancing productivity and sustainability in agriculture. Methodology: Shivapura-1 micro-watershed (Shivapura sub-watershed, Gundlupet taluk, Chamarajanagar district) is located in between 11041’ – 11043’ North latitudes and 76040’ – 76042’ East longitudes, covering an area of about 596 ha, bounded by Hullepura, Siddapura and Hundipura villages with an length of growing period (LGP) 120-150 days. We used soil resource map as basis for sampling farm households to test the hypothesis that soil quality influence crop selection, and conservation investment of farm households. The level of technology adoption and productivity gaps and livelihood patterns were analyses. The cost of soil degradation and ecosystem services were quantified. Results: The socio-economic outputs for the Shivapura-1 micro-watershed (Shivapura sub-watershed, Gundlupet taluk, Chamarajanagar district) are presented here Social Indicators Male and female ratio is 54.8 to 45.1 per cent to the total sample population.

About 55.5 per cent of farm households are below poverty line. The per capita monthly average expenditure is around Rs.1142. Environmental Indicators-Ecosystem Services The value of ecosystem service helps to support investment to decision on soil and water conservation and in promoting sustainable land use. The onsite cost of different soil nutrients lost due to soil erosion is around Rs. 765 per ha/year. The total cost of annual soil nutrients is around Rs. 436466 per year for the total area of 595.6 ha. The average value of ecosystem service for food production is around Rs. 30601/ ha/year. Per hectare food production services is maximum in banana (Rs. 45422) followed by sunflower (Rs. 12945), cotton (Rs. 9384), horse gram (Rs. 6715), sorghum (Rs. 5915) and maize (Rs. 5902). The average value of ecosystem service for fodder production is around Rs. 904/ ha/year. Per hectare fodder production services is maximum in sorghum (Rs. 1091) followed by and horse gram (Rs. 717). The data on water requirement for producing one quintal of grain is considered for estimating the total value of water required for crop production. The per hectare value of water used and value of water was maximum in banana (Rs. 117195) followed by cotton (Rs. 58112), sorghum (Rs. 41407), sunflower (Rs. 35645), maize (Rs. 23218) and horse gram (Rs. 21933). 3 Economic Land Evaluation The major cropping pattern is sunflower (33.1 %) followed by sorghum (25.4 %), horse gram (15 %), banana (11.9 %), cotton (4.9 %), maize (4.7 %) and safflower (4.7 %). In Shivapura 1 micro-watershed, major soil is soil of Shivapura (SPR) series is having shallow soil deep cover around 5.65 % of area. On this soil farmers are presently growing maize (50.0%) and sunflower (50 %), Hindupur (HDR) soil are also having shallow soil depth cover (45.0 %) of area, the crops are horse gram (24 %), sorghum (45 %) and sunflower (31.0 %). Devarhalli (DRH) soil series having moderately shallow soil depth cover around 31.66 per cent of areas, crops are sorghum (50 %) and sunflower (50.0 %). Hullipura (HPR) soil series having moderately shallow soil depth cover around 19 % of area; crops are banana (38), cotton (16 %), sorghum (23 %) and sunflower (11.0 %). The total cost of cultivation and benefit cost ratio (BCR) in study area for sorghum range between Rs. 24166/ha in HPR soil (with BCR of 1.30) and Rs. 20250/ha in HDR soil (with BCR of 1.34). In horse gram the cost of cultivation range between Rs 18606/ha in HPR soil (with of 1.26) and Rs.16253/ha in HDR soil (with BCR of 1.52). In sunflower the cost of cultivation range between Rs. 40912/ha in HPR soil (with BCR of 1.03) and Rs. 16518/ha in DRH soil (with BCR of 2.22). In maize the cost of cultivation is Rs. 24498/ha in SPR soil (with BCR of 1.24). In banana the cost of cultivation is Rs. 62539/ha in HPR soil (with BCR of 1.69) and cotton cultivation in HPR soil is Rs.74271/ha (with BCR of 1.13). The land management practices reported by the farmers are crop rotation, tillage practices, fertilizer application and use of farm yard manure (FYM). Due to higher wages farmer are following labour saving strategies is not prating soil and water conservation measures. Less ownership of livestock limiting application of FYM. It was observed soil quality influences on the type and intensity of land use. More fertilizer applications on deeper soils to maximize returns. Suggestions Involving farmers is watershed planning helps in strengthing institutional participation. The per capita food consumption and monthly income is very low. Diversifying income generation activities from crop and livestock production in order to reduce risk related to drought and market prices. Majority of farmers reported that they are not getting timely support/extension services from the concerned development departments. 4 By strengthing agricultural extension for providing timely advice improved technology there is scope to increase in net income of farm households. By adopting recommended package of practices by following the soil test fertiliser recommendation, there is scope to increase yield in horse gram (28.5 to 24.1 %), sorghum (53.8 to 47.2%), sunflower (41.4 to 24.1 %), banana (62 %), cotton (15.6 %) and maize (77.1 %). |
