Detailed soil survey was conducted at Krishi Vigyan Kendra, Bellampalli in Mancherial district of Telangana state which is newly established on 17th, March, 2018. In this study, field wise geo-referenced, physico-chemical characteristics and nutrients status of soils were studied. The soils are very shallow to moderately deep. The surface soils are neutral to strongly alkaline in reaction (6.95-8.89) with non-saline in nature (0.11to 0.51 d Sm-1), low to medium in organic carbon (3.1- 6.6 g kg-1) and CaCO3 (1.9- 8.0 g kg-1). The surface and subsurface soils (0-15 and 15-30 cm) are low in available N (127.48 to 251.25 and 102.5 to 209.37 kg ha-1), low to medium in available P (10.15 to 18.76 and 7.15 to 14.35 kg ha-1), low too high in available K (287.48-368.32 and 136.95 to 178.29 kg ha-1) and available S (6.63 to17.8 and 2.42 to 9.8 mg kg-1) respectively. Further, the soils are deficient to sufficient in available Zn (0.25to 0.82 and 0.11 to 0.56 mg kg-1), Fe (0.86 to 11.76 and 0.06 to 8.28 mg kg-1), Mn (0.51to 6.77 and 0.23 to 4.53 mg kg-1), B (0.17 to 1.26 and 0.10 to 0.72 mg kg-1) and sufficient in available Cu (0.57 to 1.98 and 0.11 to 1.24 mg kg-1) in the surface and sub-surface samples respectively. The land evaluation for soil suitability indicates that these are high to moderately suitable for cultivation of irrigated dry crops such as sorghum, maize, redgram, greengram, sunhemp, blackgram, soybean, groundnut, sunflower, sesame, high density cotton and horticultural crops. Soil productivity can be improved by providing irrigation, addition of organic matter, tank silt, black clay soils and erosion control practices.
