The study conducted on village Albaras district Durg Chhattisgarh on GPS-based surface soil samples (0-15 cm) and fertilizer recommendation for major crop. The soil pH, EC and OC of research area varied from 5.87 to 7.85 (mean 6.91), 0.11 to 0.26 dS/m (mean 0.17 dS/m) and 0.37 to 0.75% (mean 0.56%) respectively. The available nitrogen content in the soils of the study area ranged from 100.35 to 263.42 kg/ha, with a mean value of 175.52 kg/ha. Phosphorus availability varied from 9.19 to 30.67 kg/ha, with an average of 17.87 kg/ha. Potassium levels ranged from 168.54 to 637.41 kg/ha, averaging 385.04 kg/ha. Sulphur content ranged between 11.03 and 32.51 kg/ha, with an average of 19.17 kg/ha. As for the available micronutrients, Iron (Fe), measured through DTPA extraction, ranged from 5.79 to 29.78 mg/kg with a mean of 17.34 mg/kg. Manganese (Mn) levels ranged from 4.94 to 29.14 mg/kg, with an average of 13.34 mg/kg. Copper (Cu) concentrations ranged from 0.56 to 2.88 mg/kg, averaging 1.61 mg/kg. and zinc (Zn) content ranged from 0.22 to 1.96 mg/kg, with a mean of 0.78 mg/kg. In the study region the soil fertility status was evaluated by using Nutrient Index Value. Overall ratings were assessed as low (1.00), medium (1.84) and high (2.62) in available N, available P and available K, respectively based on NIV was reported. As for available S and micronutrients, sulfur and boron recorded as low (1.19) and (1.06) respectively, and Zn was medium (1.87) while Fe, Mn and Cu were in high category of NIV (2.87, 2.86 and 3.00, respectively). As a whole, available N, S, and B are the major nutrient constraints in the study area.
