Abstract: A study was conducted to assess available micro nutrient status of soils of Pathardi Tehsil of Ahmednagar District by GIS technique. 199 soil samples (0-22.5 cm) drawn during 2014 from the 70 villages were analyzed for their fertility status and mapped by geographic information system (GIS) technique. The exact locations of soil samples were recorded with the help of GPS. The results indicated that all samples were slightly alkaline to moderately alkaline in soil reaction (7.09-8.39), non-saline (0.11 -0.58 dS m-1), low to moderately high in organic carbon (0.22-0.74 %) and Calcium Carbonates ranged from (5.75-13.0 %). Regarding to micronutrients, the soils were sufficient in available Fe, Mn, Zn, Cu, B and Mo which ranged between (1.13- 5.96 mg kg-1), (2.65- 3.96 mg kg-1), (0.19- 0.74 mg kg-1), (1.15- 7.72 mg kg-1), (0.25-0.77 mg kg-1) and (0.026-0.068 mg kg-1) respectively, whereas Mn, Cu and Mo were sufficient and Fe, Zn and B were poorly deficient to sufficient in soil. The pH of the soils recorded negative and non-significant correlation with available Mn and Mo. It was positive and non-significant correlation with available Fe, Zn and B. While negative and significant with available Cu. The EC showed positive and non-significant correlation with available Fe, Zn, B and Mo While negative and significant correlation with available Mn. Organic carbon showed negative and non-significant correlation with available Mn and positive and non-significant correlation with available Fe, Zn and Mo. While B showed negative and significant correlation with organic carbon. CaCO3 was negative and non-significantly correlated with available Mn, Zn, Mo and positively correlated with available Cu and B.
