LAND RESOURCES INVENTORY OF SELECTED MICRO WATERSHEDS OF YADGIR. USING REMOTE SENSING AND GIS TECHNIQUES

      Аннотация: A LRI survey was conducted for two micro watersheds viz., Kolur and Malhar1 micro watersheds which are located in Yadgir taluk of Yadgir district, Karnataka at 1:10000 scale to characterize, classify, assess land degradation status, soil fertility and evaluate land capability, crop suitability and assess SQI and productivity constraints and estimate erosion loss of Kolur and Malhar1 MWSs of Hyderabad Karnataka region. The soils were moderately shallow to deep in both the MWSs. The colour of soils varied from 7.5YR 3/3 (dark brown) to 10YR 5/4 (yellowish brown). The soil texture varied from sandy loam to clay. The series Killankera, Koiloor were classified under Typic haplustepts and Hosahalli, Lingeri Tanda and Malhar as Vertic haplustepts. Kolur and Bheema series had sub group of Typic hapluesterts. Malhar Tanda series were grouped under Typic haplusterts. Water erosion and water-logging were the major types of land degradation noticed in the study area. The soil series of Kolur and Malhar1 MWSs were grouped into two land capability classes with four sub classes. Out of fifteen mapping units of both Kolur and Malhar1 MWSs, Bheema and Kolur series were grouped as class III and rema
