Physico-chemical Properties of Cotton Growing Soils in Uppununthala Mandal, Nagarkurnool District, Telangana, India

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).
