Abstract:
Soybean is an important oilseed crop predominantly grown in Adilabad district. Investigating the fertility status of soybean growing soils is required to under pin future land use planning. A survey was carried out in major soybean growing soils of Adilabad district of Telangana state. One hundred and ten representative surface soil samples (0-15 cm) were collected and analysed for their salient characteristics viz., pH, EC, OC, available N, P2O5, K2O, S and micronutrients (Zn, Fe, Cu and Mn). Soil fertility maps were prepared for macro and micro nutrients. Results revealed that, soil pH ranged from 6.10 to 8.51. The soils were non-saline to slightly saline (0.14 to 1.26 dSm-1). The organic carbon ranged from 0.18 to 0.80 per cent. With regard to available nutrients, the values varied from 105 to 241 kg/ha for nitrogen, 9.7 to 98 kg/ha for phosphorus, 198 to 395 kg/ha for potassium and 6.12 to 25.32 mg/kg for sulphur. Among the micronutrients 61.81 and 22.72 percent soils were deficient in available zinc and iron, respectively. Further, the soils were not deficient in Cu and Mn.
