GPS-GIS based soil fertility maps of Sangamner tahsil of Ahmednagar district (M.S.)

Abstract

Plant nutrients supply from chemical fertilizers plays a vital role in increasing agricultural production by enhancing the soil quality and productivity. The GPS and GIS techniques i.e. (Global Position System and Geographical Information System) are widely utilized for delineating fertility maps of macro and micronutrients. The study entitled GPS-GIS based soil fertility maps of Sangamner tahsil of Ahmednagar District (M.S) was conducted during the year 2013-2014 and 2014-2015 at Department Soil Science and Agriculture Chemistry, Post Graduate Institute MPKV, Rahuri to assess the macro nutrient status of Sangamner tahsils of Ahmednagar district based on GPS and delineation of fertility maps.
