Farm-Scale Mapping of Soil Microbiological Indicators Using Geostatistical Technique

Tapan Gorai, Nayan Ahmed & Rabi Narayan Sahoo · International Journal of Environment and Climate Change · 2023

Soil microbiological properties viz. soil microbial biomass carbon (MBC) and dehydrogenase activity (DHA) are sensitive soil quality indicators. Spatial modeling and prediction map of soil MBC and DHA were generated for a semiarid agricultural farm, New Delhi, India from 288 geo-...

Farm-scale Mapping of Soil Phosphorus and Potassium Fractions Using Geostatistical Technique

Tapan Gorai, Nayan Ahmed & Rabi Narayan Sahoo · International Journal of Plant & Soil Science · 2022

Phosphorus (P) and potassium (K) are two major nutrients for agricultural productivity and sustainability. The spatial variability maps of soil phosphorus and potassium content in surfacesoils collected through grid sampling technique were developed using geo-spatial technology f...
