GPS based sampling for determination of fertility status of some villages of Jatani block of khordha district, Odisha

Abstract

Precision agriculture is the need of hour and GPS soil sampling is an important tool to achieve it. This as a result helps us to have site specific nutrient management. A GPS based soil sampling was done from some villages of Jatani block, khordha district of Odisha. The pH ranged from strongly acidic to neutral, organic carbon was low in most of sample, status of macronutrients like nitrogen, phosphorous, potassium, sulphur were low for most of sample where as calcium and magnesium was found out to be sufficient. Fertilizer dose as per the nutrient status can be recommended and thus suitable crop can be selected for better yield and sustainable agriculture.
