A research was conducted to study the fertility status of soils from kaleshwaram project command area of erstwhile Nizamabad district in Telangana. A total of 72 geo-referenced soil samples collected from surface (0-15cm) by using GPS coordinate. Samples were analysed for important soil parameters viz., pH, EC, available macronutrients (N, P, K) and micronutrients (Fe, Zn, Mn, Cu). Correlation study was done to study the relation between the various soil properties. The soil pH and EC showed wide variation that soils are low acidic to medium alkaline in reaction and low salinity. Whereas available N content is low (75 to 298 kg ha-1), available P2O5 content medium to high (18-358 kg ha-1) and available K2O content low to high (90 to 630 kg ha-1). The soil available Zn, Cu, Fe and Mn contents of surface soils are very low to adequate. Correlation study depicts that soil reaction was negatively related with soil available N, P2O5, Fe and Mn. the results of the study area showed that these soils are need proper management, supplement with organic manures and inorganic fertilisers. |
