Soil fertility status of organic carbon and available nitrogen 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 study on “Soil fertility status of organic carbon and available nitrogen in soil through Soil fertility mapping using GPS and GIS techniques of Dharmaur micro-watershed Jagdalpur block, Bastar district of C.G. state” was carried out during 2017.The objective of the study were to quantify the soil fertility status of organic carbon and available nitrogen in the soils of Dharmaur micro-watershed through soil fertility mapping using GPS and GIS techniques. Soil fertility maps were adapted by using the Kriging technique of geostatistical interpolation method. Soil fertility mapping of the study area will be conducted on 1:10000 scale. Grid point based surface soil samples (0-15 cm) will be collected, dried, ground, and stored for laboratory analysis.Total 382 soil samples are collected from the area covers the majority of the part of Kumhrawand and Tekameta villages and 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 at the distance of 100 metres.
