Abstract

The present study was carried out to know the fertility status of Patancheru area of Sanga Reddy district, Telangana state by using GPS-GIS technology during the year 2020-2021. Total 132 soil samples from soil surface (0-20 cm) collected from the study area and analyzed for the soil physico-chemical properties (pH, EC, OC), available macronutrients (N, P, K, S, Ca, Mg)
and available micronutrients (Fe, Mn, Cu, Zn). Their status was quantified and analytical data was interpreted and statistical parameters like range, mean, standard deviation and coefficient of variation were calculated. The pH of soils of study area varied from 6.14 to 9.20, most of the soils were found to be moderately to strongly alkaline (84.1 per cent) while EC varied from 0.09 to 4.33 dS m-1, 99.32 per cent the soils were found to be high to very high in salinity. Organic carbon content varied from 0.11 to 1.25
per cent and categorized as low (5.0 per cent), medium (79.3 per cent) and high (15.7 per cent) content in soils. The soil available nitrogen, phosphorus and potassium ranged from 37.5 to 475.0, 15.4 to 59.8 and 176.2 to 1023.9 kg ha-1, respectively. The soils were low (98.1 per cent) in available nitrogen. In respect of available phosphorus were medium (99.3 per cent). In case of available potassium were medium in 89.6 per cent of soils. The available sulphur varied from 0.5 to 32.1 mg kg-1. The soils were medium (76.6 per cent) in available sulphur content. The exchangeable calcium and magnesium were sufficient in all samples. Available Zn, Cu, Fe and Mn were deficient in 90.7, 45.6, 98.4 and 88.8 per cent of soils respectively.
