This study focused on the spatial distribution and
assessment of soil fertility parameters in Shahdol district of Madhya Pradesh
using a GIS approach. The physical parameters of soil (pH, EC, OC) and macro
nutrients (N, P, K) were considered as key factors for soil fertility mapping.
Nutrient data were sourced from the geoportal of the Department of Science and
Technology in Madhya Pradesh and were subsequently used for spatial variability
map generation. Through a comprehensive geo-spatial analysis of plant nutrient
availability, soil fertility maps were created as vital instruments for
effective soil and nutrient management, ultimately enhancing sustainable
agricultural productivity. The findings indicated that the majority of the
soils examined fell within the slightly acidic to neutral pH range, with
organic carbon levels distributed as follows: 33.19% in the low category,
65.53% in the medium category, and 1.28% in the high category. The available
nitrogen levels ranged from 132.2 to 396.61 kg ha-1, available
phosphorus levels spanned from 15.48 to 45.09 kg ha-1, and available
potassium levels varied from 97.96 to 325.95 kg ha-1. Integrating this
quantitative data with the developed soil fertility maps for Shahdol district
will be key to optimizing soil nutrient management strategies, thereby
enhancing crop yields and quality.
