An Investigation on physico-chemical properties, NPK and micro nutrient status of soils of Janpad major, Left bank canal, Nagarjuna Sagar Project (NSP), Telangana, India was carried. The soils are having clay content ranging from 6 to 24 per cent, silt content from 4 to 20 per cent and sand content from 69 to 87 per cent. The Hydraulic conductivity varied from 15 to 20 cm day-1 with a mean value of 17.5 cm day-1. Mostly the soils under the command area are slightly acidic to slightly alkaline and non-saline in nature. Of the total soil samples, 69 per cent of samples were low and 26 percent samples were medium in organic carbon. The available nitrogen was low in all soil samples (61), the available phosphorus was high in 87 % samples and the potassium content in 43 per cent samples was low, 46 per cent samples medium. All soil samples (61) under command area were above the critical level in Iron, Copper and Manganese. On the other hand, 15 per cent samples were found to be deficient in DTPA-extractable Zn and require Zn application for optimum production and to get full benefit from NPK fertilization.
