Abstract/Description: | The land resource inventory of Gopalagiri Colony-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 550 ha in Gopalagiri Colony-1 microwatershed in Gundlupet taluk of Chamarajanagar district, Karnataka. The climate is semiarid and categorized as drought prone with an average annual rainfall of 734 mm. Maximum of 254 mm precipitation takes place during south–west monsoon period from June to September, the north-east monsoon contributes about 268 mm and prevails from October to early December and the remaining 212 mm takes place during the rest of the year. An area of about 95 per cent is covered by soils and 5 per cent by waterbodies, settlements, forest and others. The salient findings from the land resource inventory are summarized briefly below. The soils belong to 10 soil series and 35 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 3rd 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 major agricultural and horticultural crops were assessed and maps showing the degree of suitability along with constraints were generated. About 95 per cent area is suitable for agriculture and 5 per cent is not suitable for agriculture but well suited for forestry, pasture, agroforestry, silvi-pasture, recreation, installation of wind mills and as habitat for wildlife. About 41 per cent of the soils are very deep (>150 cm), 22 per cent deep to moderately deep (75 - 150 cm), 33 per cent are moderately shallow to shallow (25-75 cm). About 65 per cent of the area has clayey soils, 26 per cent loamy soils and 3 per cent sandy soils at the surface. About 47 per cent of the area has non-gravelly (<15% gravel) soils, 38 per cent gravelly soils (15-35 % gravel) and 9 per cent very gravelly to extremely gravelly soils (35- 80% gravel). About 41 per cent of the area has soils that are very high (>200mm/m) in available water capacity and about 54 per cent low (50-100 mm/m) and very low (<50mm/m) in available water capacity. About 94 per cent of the area has gently sloping (3-5%) to very gently sloping (1-3% slope) lands, 6 per cent has nearly level (0-1%). An area of about 44 per cent has soils that are slightly eroded (e1) and 50 per cent moderately eroded (e2). An area of about 17 per cent has soils that are neutral in reaction (pH 6.5 to 7.3), 28 per cent slightly alkaline (pH 7.3-7.8), 25 per cent moderately alkaline (pH 7.8 to 8.4), 24 per cent slightly acid (pH 6.0-6.5) to moderately acid (pH 5.5-6.0) in reaction. The Electrical Conductivity (EC) of the soils are dominantly <2 dsm-1indicating that the soils are non-saline. About 66 per cent medium (0.5-0.75%), 23 per cent low (<0.5%) and 7 per cent high (>0.75%) in organic carbon. An area of 34 per cent has soils that are low (<23 kg/ha), an area of 43 per cent medium (23-57 kg/ha) and 17 per cent high (>57 kg/ha) in available phosphorus. About 9 per cent medium (145-337 kg/ha) and 85 per cent high (>337kg/ha) in available potassium. Available sulphur is low (<10 ppm) in about 84 per cent area and medium (10-20 ppm) 11 per cent in available sulphur. Available boron is low (<0.5 ppm) in about 45 per cent area and 50 per cent medium (0.5-1.0 ppm). About 33 per cent area has soils that are deficient (<4.5 ppm) in available iron and 62 per cent sufficient (>4.5 ppm). Available manganese and copper are sufficient in all the soils. About 70 per cent area has soils that are deficient (<0.6 ppm) in available zinc and 25 per cent sufficient (>0.6 ppm). The land suitability for 27 major crops (agricultural and horticultural) 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: Gopalagiri Colony-1 micro-watershed (Basavapur sub-watershed, Gundlupet taluk, Chamarajanagar district) is located in between 11043’ – 11044’ North latitudes and 76035’ – 76037’ East longitudes, covering an area of about 550 ha, bounded by Kannagal, Honnegaudanahalli, Hangala and Hosalhalli villages with 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 Gopalagiri Colony-1 micro-watershed Basavapur sub-watershed, Gundlupet taluk, Chamarajanagar district are presented here.

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. 185838) followed by turmeric (Rs. 54978), sorghum (Rs. 53775), bajra (Rs. 52269), red 3 gram (Rs. 51718), sunflower (Rs. 39261), maize (Rs. 37562), groundnut (Rs. 23392), horse gram (Rs. 22578) and ragi (Rs. 15479). Economic Land Evaluation The major cropping pattern is bajra (29.8 %) followed by horse gram (12.8 %), groundnut (10.9 %), red gram (10.8 %), maize (10.4 %), sunflower (10.4 %), turmeric (6.2 %), banana (5.4%), safflower (2.3 %) and sorghum (0.9 %). In Gopalgiri colony 1 micro-watershed, major soils are Annurkeri (ARK) soil series are having deep soil depth cover around 18.25 per cent of area. On this soil farmers are presently growing groundnut (46.8 %), turmeric (26.78 %) and bajra (26.5 %). Bheemanabeedu (BMB) soil series are having deep soil depth cover around 14.9 per cent of area; the major crops grown are sunflower (83.3 %) and sorghum (16.7 %), Devarahalli (DRH) having moderately shallow soil depth covers around 10.83 per cent of area and the major crops grown are bajra (39.4 %), red gram (39.4 %) and banana (21.2 %). Hullipura (HPR) soil series having moderately shallow soil depth cover 4.96 per cent of area. On this soil crops are horse gram and ragi. Kannigala (KNG) soil series having moderately deep soil depth cover around 4.29 per cent of area in this soil maize (50 %) and sunflower (50 %) are grown. Maddinahundi (MDH) soil series having deep soil cover 5.29 per cent of area. In this soil bajra and horse gram. The total cost of cultivation and benefit cost ratio (BCR) in study area sunflower range between Rs. 57430/ha in BMB soil (with of 0.98) and Rs. 34393/ha in KNG soil (with BCR of 1.26). In turmeric the cost of cultivation is Rs. 220347/ha in ARK soil (with BCR of 1.2). In banana the cost of cultivation is in DRH soil Rs. 115113/ha (with BCR of 1.8). In groundnut the cost of cultivation is Rs. 39081/ha in ARK soil (with BCR of 1.1). In sorghum the cost of cultivation is Rs 42790/ha in BMB soil (with BCR of 1.07). In horse gram the cost of cultivation range between MDH soil is Rs. 20809/ha (with BCR of 1.74) and Rs 32697/ha in HPR soil (with BCR value of 1.3). In red gram the cost of cultivation is in DRH soil is Rs 21177/ha (with BCR of 1.9) and ragi cost of cultivation Rs in HPR soil is 54721/ha (with BCR of 1.1). 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 are deeper soils to maximize returns. Suggestions Involving farmers is watershed planning helps in strengthing institutional participation. 4 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. By strengthen 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 bajra (11.2 % to 28.8%), banana (39.8%), red gram (22.1 %), horse gram (14.6% to 35.1 %), ragi (55.8 %), maize (63.0 %), sunflower (24.1 % to 32.5 %), ground nut (50.8 %) and sorghum (37.1%). |
