| dc.description.abstract | A study was undertaken to characterize and classify the soil resources of Bhanapur microwatershed (Koppal district) for sustainable land use planning and to assess fertility status of the soils. Eight soil profiles and one hundred surface samples were included in the study. The microwatershed consists of both red and black soils in association. The texture of red soils was sand and that of black soils was clay with low and high water holding capacity respectively. Bulk density of red soils was higher than black soils and showed irregular trend with depth. The soils were slightly acidic to alkaline in nature with low organic carbon content. Calcium carbonate content varied throughout the depth of profiles with low values in red soils (2.00% to 4.90%) and higher in black soils (3.10% to 18.00%)). Calcium and magnesium were the dominant exchangeable cations followed by sodium and potassium. The black soil pedons under study were classified as veiy fine, clayey, montmorillonitic, calcareous, isohyperthermic, TYpic Haplusterts, and red soil pedons belonged to Entisols and Alfisols. Pedon 1 was classified as fine silty, mixed isohyperthermic, deep, lypic Ustifluents. The pedons 2, 3 and 4 were classified as loamy, mixed, isohyperthermic, psammatic Haplustalfs. The pedon 5 was loamy, mixed, isohyperthermic, Typlc Haplustalfs. Six phases were identified in the study area and mapped into six mapping units by GIS technique. Land capability classification showed that majority of soils belonged to class III and IV lands with limitations of erosion, wetness and soil properties. Soil site suitability evaluation for wheat, cotton, sorghum, sunflower, maize, chilli, potato, pigeonpea, paddy and pearl millet showed that red soils were moderately suitable (S2) for groundnut and marginally suitable (S3) for other crops and paddy, wheat and potato were not suitable. The black soils were moderately suitable for pearl millet and sunflower. Remaining crops were marginally suitable. | en_US |
