Abstract: The study of soil survey was carried out during the year 2017-18 to 2018-19in Nandurbar district (M.S) India by using GPS techniques in Agro-Ecological-Sub-Region (AESRs) of Nandurbar district namely, AESR 6.2 a (K4Dd4). AESR 6.2 a 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 fifteen soil samples were collected from various villages of three tehsils of Nandurbar district were analyzed for their fertility and micro and secondary nutrient status. The exact locations of soil samples as well as latitude, longitude and altitude were recorded by the help of Global Positioning System (GPS). The result revealed that all the soil samples in Nandurbar district are slightly acidic to slightly alkaline in nature (6.45 -7.99), electrical conductivity are non–saline (0.16-0.52 dS m-1), moderate to high in organic carbon (4.67-9.67 g kg-1) and calcium carbonate ranged from 1.45-5.63per cent. Regarding micro and secondary nutrients, the DTPA- extractable zinc, copper, iron, manganese and boron varies from 0.36-2.12, 0.89-7.89, 2.23-33.77, 10.02-35.25 and 0.12-1.50 mg kg-1with mean of 1.04,4.00,18.45,23.13 and 0.86 mg kg-1 respectively, while, exchangeable Ca (20.44-36.10 cmol (p+) kg-1) and Mg (11.78-18.72 cmol (p+) kg-1) was found sufficient. The available sulphur varies from 3.66-40.99 with mean of 24.41 mg kg-1 was found sufficient in soil. Significant and positive correlation with DTPA- Cu and OC whereas, the relation between pH and CaCO3 were positively correlated. The DTPA-Fe showed negative correlation with soil pH (r=-0.209), CaCO3 (r=-0.100) and Zn (r=- 0.052) and positive relation with O.C. (r=0.023). The DTPA-Fe content positive and significant correlation with DTPA-Mn (r=0.525**) and DTPA-Cu(r=0.583**). The soils of Nanburbar, Navapur and Shahada tehsils of Nanburbar districts were 20, 13 and 27 per cent deficient of zinc, iron and boron respectively. However, copper and manganese was found sufficient. Nutrient indices values were noted high in copper, iron, manganese and sulphur and medium in boron.
