Abstract:
The study of soil survey was carried out during the year 2017-18 to 2018-19 in Amravati district (M.S) India by using GPS techniques in Agro-Ecological-Sub-Region (AESRs) of Amravati district namely, AESR 6.3 a (K5Dm4). AESR 6.3 a is characterized by Deccan Plateau, dominantly black soils, hot semi- arid and length of growing period 180-210 days, moderately well drained soil. For this purpose 15 representative soil samples (0-20 cm) were collected from different villages of three tehsils of Amravati district. These soil samples were analysed for soil properties and micronutrient fertility status of soil. The exact locations of soil samples as well as latitude, longitude and altitude were recorded by the help of Global Positioning System (GPS).The soils under the study of Amravati district were alkaline in nature, safe in limit of electrical conductivity and moderately calcareous to calcareous in nature.However,DTPA-Cu, Fe and Mn was recorded in high quantity, while DTPA-Zn medium ranged. The DTPA- Zn indicated negative and significant relationship with CaCO₃ (r= -0.317*) while, DTPA-Zn was positively and significant correlation with B (r=0.632**). Exchangeable Ca was found sufficient while, exchangeable Mg and available S were found in medium. According to nutrient index value of the soils of Amravati district were found in medium category for available Zn, Fe, boron and sulphur while high with respect to available Cu and Mn.
