In the years 2020-2021, research was carried out in the Indore District of Madhya Pradesh to determine the soil reaction, electrical conductivity, organic carbon content, and primary nutrient status. A cadastral map of the study region was used to grid-in the collection of surface soil samples, which were analyzed for fertility. The pH, electrical conductivity, and organic carbon levels varied from 6.38 to 8.49, 0.19 to 0.99 dSm^-1, and 0.14 to 0.76%, respectively. Available nitrogen, phosphorus, potassium, and sulfur concentrations varied from 95,2 to 246,4 kg ha^-1, 8,12 to 22,92 kg ha^-1, and 250 to 700 kg ha^-1, 3,29 to 34,21 mg kg^-1, respectively. Available nitrogen was low, phosphorus varied from low to high, and potassium was medium to high, and sulfur varied from low to high. Using the field survey and the results of laboratory analyses, the units of soil heterogeneity were determined using Arc-GIS 10.4.1. Based on the data obtained after the analysis; maps of all parameters were prepared, which will be successfully used for site-specific nutrient management in the future.
