Abstract: Soil is vital for human beings and the ecosystem; therefore, determining its potential is necessary. The present study aimed at understanding the soil fertility status using ‘Nutrient Index approach’ and presenting their spatial variability through maps, which will be beneficial and effective for maintaining nutrients management and sustainable agricultural production. Georeferenced soil samples collected from 20 sites were analyzed using standard procedures for various parameters like ‘pH’, ‘Soil Organic Carbon (SOC)’, ‘Electrical Conductivity (EC)’, available ‘Nitrogen (N)’, ‘Phosphorous (P)’ and ‘Potassium (K)’. All soils from the study area were acidic with negligible effect of salt for EC. In the case of SOC, N, P and K, the calculated values from Nutrient Index showed high status of SOC, medium for N and K, while low for P. Land use change was observed to have a remarkable influence on soil properties in the study area. The ‘Inverse Distance Weighting (IDW)’ interpolation method in ArcGIS software was employed to create spatial distribution maps for different soil parameters.
