Tilendri, RN Singh, GP Ayam and Vikas Patel
The study “Evaluation of soil Fertility statsus of Bhatpal Village, Bastar district, Chhattisgarh” was conducted in 2024-25 to assess soil nutrient status. A total of 120 surface soil samples (0-15 cm) were analyzed for pH, EC, organic carbon, macronutrients (N, P, K), secondary nutrient (S), and micronutrients (Fe, Mn, Cu, Zn, B). Soils were moderately to slightly acidic (pH 4.41-7.52), with EC values indicating suitability for crops, (ranges 0.01-0.13dSm-1). Organic carbon was medium in most samples, (ranges 0.37-0.72%). Most of the soil samples were found low in available N content varied from 163.07 to 250.88 kg ha-1 with mean 219.41 kg ha-1. The available phosphorus (Olsen P) ranged from 8.96 to 28.28 kg ha-1 with mean 15.96 kg ha-1 while phosphorus (Bray P-1) was ranged from 28.28 to 54.32 kg ha-1 with mean 34.34 kg ha-1. The available potassium ranged from 130.59 to 229.48 kg ha-1 with mean 199.52 kg ha-1. The available sulfur ranged from 11.51 to 20.83 kg ha-1 with mean 15.83 kg ha-1. The nitrogen content of the soil indicates that the entire study are region showed low level of available nitrogen, Olsen P content of the area was low, medium to high with 61 percent low, 27 percent of the examined area showing medium levels and only 12 percent were showing high levels of available phosphorus, while available phosphorus (Bray P-1), P content of the area was low to medium, with 57 percent low and 43 percent of the examined area showing medium levels. The potassium content of the area was low to medium with 12 percent of the examined area showing low levels and 88 percent showing medium levels of available potassium and sulfur content of the area was low to medium with 86 percent exhibited low and 14 percent showed medium levels of available sulphur. Among micronutrients iron (Fe) ranged from 7.32 to 39.92 mg kg-1 with mean 34.25 mg kg-1, 6.96 to 27.98 mg kg-1 with mean 24.23 mg kg-1 for Mn, 0.98 to 1.56 mg kg-1 with mean 1.34 mg kg-1 for Cu, and 0.54 to 0.78 mg kg-1 with mean 0.66 mg kg-1 for Zn, respectively. The available B ranged from 0.31 to 1.74 mg kg-1 with mean 0.48 mg kg-1. Micronutrients Fe, Mn, and Cu were sufficient; however, 18% samples were deficient in Zn and 80% in B. Based on Nutrient Index Value (NIV), N, P, and S were low, K was medium. Recommendations include liming acidic soils, applying 25% additional N, P, S, and K where deficient, and applying 25 kg/ha Zinc Sulphate and Borax where Zn and B are low.
