Soil fertility status of available potassium in soil through soil fertility mapping using GPS and GIS techniques of Dharmaur micro-watershed Jagdalpur block, Bastar district of (C.G.) state

Abstract

The present research on the soil fertility status of available potassium in soil by soil fertility mapping using GPS and GIS techniques of the Dharmaurmicro watershed Jagdalpur block, Bastar district of C.G. was conducted during 2017-18. The focus here was to prepare soil fertility mapping using GPS and GIS techniques. We quantified the available potassium in the soils of the study area using GPS-based grid samples and created soil fertility maps using geostatistical methods. A total of 382 soil samples were collected from the area covering most of Dharmaur, Kumhrawand and Tekameta villages and the study area is surrounded by Kumhrawand village to the East, Tekameta village to the West, Indravati river to the North and Bhadisgaon & Biringpal villages to the South.
