Abstract: The study of soil survey was carried out during the year 2017-18 to 2018-19 in Nilanga tehsil of Latur district (M.S) India by using GPS techniques in Agro-Ecological-Sub-Region of (AESRs) Latur district namely, AESR 6.2 c (K4Dd4). AESR 6.2 c which is characterized by Deccan Plateau, soils is shallow and medium (inclusion deep) black soils, semi- arid dry and length of growing period 180-210 days. 0-20 cm depths of five soil samples collected from Nilanga tehsil in latur district were analyzed for their fertility and micronutrient status. The exact locations of soil samples were recorded by the help of Global Positioning System (GPS). The result revealed that the soil of Nilanga tehsil shows clay is greater hence it comes under clay type textural classification. All the soil samples neutral to moderately alkaline in reaction (7.50-8.34), electrical conductivity are non–saline (0.12-0.33 dS m^-1), low to moderately high in organic carbon (3.86-7.54g kg^-1) and calcium carbonate ranged from 4.25- 8.13 per cent and showed soils are moderately calcareous to calcareous in nature. Regarding micro and secondary nutrients, The DTPA-extractable zinc, copper, iron, manganese and boron varies from 0.39-0.87, 3.61-10.08, 18.32-32.00, 30.62-65.94 and 0.28-0.55 mg kg^-1 with mean of 0.56, 6.04, 28.69, 46.98 and 0.37 mg kg^-1 respectively, while, exchangeable Ca (14.65-31.45cmol (p⁺) kg^-1) and Mg (12.12-27.65cmol (p⁺) kg^-1) with mean of 23.32 and 20.63 cmol (p⁺) kg^-1respectively, and found sufficient. The available sulphur varies from 10.18-14.58 with mean of 12.43 mg kg^-1 was found medium in soil. The soils of Nilanga tehsils of Latur districts were 60 and 80 per cent deficient of zinc and boron respectively. However, the copper, iron and manganese were found sufficient, Nutrient indices values were noted high in copper, iron, and manganese and medium in sulphur.
