Soil Macro and Secondary Nutrients Status of Pathardi Tehsil of Ahmednagar District. (M.S.)

Abstract

A survey was conducted to know available macro and secondary 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 macro and secondary nutrients, the available N, P and K which ranged between (62.72.-338.68 kg ha-1), (3.31-19.64 kg ha-1) and (302.4-571.2 kg ha-1), respectively, whereas exchangeable Ca and Mg was sufficient in soils and available S is ranged between (8.4- 20.4 mg kg-1) was slightly deficient to sufficient in soil.
