A systematic set of geo-referenced samples was collected from Instructional Farm, College of Agriculture, district Raipur, Chhattisgarh covering the entire area using GPS (Global positioning system) and fertility status map was generated by integrating the individual nutrient map in Arc Map 10.3. A random sampling procedure was used to gather surface (0-15 cm) soil samples, yielding a total of 126 samples for analysis of soil chemical characteristics. Soil response (pH), electrical conductivity (EC), organic carbon (OC), available macro-nutrients (e.g. N, P, K, S), & DTPA-extractable micro-nutrients (e.g. Iron, Manganese, Copper, Zinc, and hot water extractable Boron) were all tested in the soil samples. The soil pH of the study region ranged from 6.51 to 7.78. It indicates that the pH of the soil is in the neutral to slightly alkaline range. The electrical conductivity found to be fall under the normal category with average value of 0.25 dS/m. Organic carbon in this soil was found to be around 0.38%. Available Nitrogen content was found between 163 to 278 kg ha^-1. The available Phosphorus content varied from 2.6 to 28.9 kg ha^-1. Available Potassium content ranged from 201.23 to 443.96 kg ha^-1. The available sulphur content ranged from 9.32 to 36.67 kg ha^-1. DTPA extractable micronutrient anions content was found that the Iron content varied from 4.1 to 31.4 mg kg^-1. The Manganese content ranged between 2.2 to 22 mg kg^-1. Copper content varied from 0.4 to 1.7 mg kg^-1. Zinc content ranged from 0.4 to 2.3 mg kg^-1. Hot- water soluble Boron content found to be between 0.1 to 0.8 mg kg^-1.
