Abstract:
Soil fertility assessment in a territory or region is the most basic decision making tool for sustainable soil nutrient management. In order to Soil Fertility Status of Research Farm, College of Agriculture and Research Station Kurud, District Dhamtari, Chhattisgarh. Randomly 110 soil samples (0-15 cm) were collected based on the handheld GPS location. The collected samples were analyzed for Chemical parameters of soil like, pH, EC, OC, available N, P, K, S, DTPA- extractable Fe, Mn, Zn, Cu, Hot water extractable B and physical properties of soil like soil texture, bulk density, particle density and porosity. The pH ranged from 6.50 to 7.30, which means they were neutral in reaction. The electrical conductivity found to be fall under the normal category with average value of 0.14 dS/m. Organic carbon in this soil was found to be around 0.46%. Available Nitrogen content was found between 100.35 to 188.16 kg ha^-1. The available Phosphorus content varied from 2.68 to 15.23 kg ha^-1. Available Potassium content ranged from 286.60 to 399.84 kg ha^-1. The available Sulphur content ranged from 11.20 to 30.80 kg ha^-1. DTPA extractable micronutrient anions content was found that the Iron content varied from 20.00 to 37.64 mg kg^-1. The Manganese content ranged between 18.62 to 37.96 mg kg^-1. Copper content varied from 1.79 to 5.80 mg kg^-1. Zinc content ranged from 0.40 to 0.68 mg kg^-1. Hot- water extractable Boron content found to be between 0.20 to 1.30 mg kg^-1. The clay content ranged from 18% to 47%. The silt content ranged from 12% to 32%. The sand particle varied from 28% to 50%. Bulk density ranged from 1.21 to 1.46 Mg m^-3. Particle density ranged between 2.11 to 2.65 Mg m^-3. Porosity ranged from 34.59% to 50.40%.
