Abstract
The aim of this study is the evaluation of soil fertility in the Uppununthala mandal of the Nagarkurnool district, Telangana. In total, fifty surface soil samples (0-20 cm) were analysed for various soil fertility parameters, viz., pH, EC, organic carbon, available N, P, K, S by standard procedures. The results revealed that, the pH of the soils of the study area were neutral to slightly alkaline (7.14 - 8.30) in nature. The electrical conductivity (0.14 to 0.55 dS m-1) was within safe limits. Organic carbon ranged from low to medium (1.9 - 7.9 g kg-1) in the soils. The data on nutrient status showed that, the available nitrogen (125.44 - 291.64 kg ha-1) was low, while available phosphorus (9.7 - 26.2 kg ha-1) was low to medium and potassium (123.20 - 360.64 kg ha-1) were medium in range. The available sulphur content ranged in medium level (10.56 to 20.62 mg kg-1).
