GPS-GIS based soil fertility maps of micronutrient status of Chandgad tehsil of Kolhapur district (M.S.)

Abstract

The present study was conducted during the year 2015-2016 with an objectives to assess the micro nutrients status of soils of Chandgad tehsil of Kolhapur district and delineate GPS - GIS based soil fertility maps and to correlate soil properties with available nutrients. One hundred and fifty four geo-referenced soil samples were collected from study area using GPS. The DTPA extractable iron, manganese, zinc and copper in soils ranged from 4.58 to 33.74, 2.32 to 30.92, 0.66 to 3.52 and 0.27 to 8.39 mg kg-1, respectively. Soils were sufficient in available iron, manganese, copper and zinc. The pH, EC and CaCO3 showed significant negative correlation with zinc, manganese and copper. Organic carbon was positively correlated with iron, zinc and manganese.
