Abstract:
A survey was conducted during pre-monsoon season of the year 2021 in Upper Banas River Basin to assess the soil fertility. The 118 soil samples collected and analyzed to find out their texture, bulk density, particle density, porosity, pH, EC, organic matter, N, P₂O₅, K₂O, CaCO₃, S, B, Fe, Zn and Cu, Mn status. The observed data revealed that bulk density was found 1.30 to 1.66 Mg m^-3, particle density found 2.18 to 2.88 Mg m^-3 and porosity varied 31.91 to 50.00% and sand, silt and clay content were 49.77%, 22.88% and 27.35%, respectively and categorized as eight different classes of texture. The soil was neutral to slightly alkaline in pH ranged from 7.00 to 7.98, electrical conductivity of soil was non saline to moderately saline ranged from 0.25 to 3.42 dS m^-1 and soil organic matter ranged from 0.05 to 0.98 per cent, respectively. The soil available nitrogen ranged from 120.39 to 488.39 kg ha^-1, available phosphorus ranged from 13.95 to 56.70 kg ha^-1, available potassium 165.95 to 416.56 kg ha^-1 and sulphur ranged from 5.03 to 15.25 mg ha^-1, respectively. The soil calcium carbonate was varied from. 58 to 4.93 per cent. Where’s the available of Zinc 0.68 to 13.47 mg ha^-1, available iron ranged varied from 1.67 to 16.00 mg ha^-1, available copper varied from 0.10 to 2.40 mg ha^-1 and available manganese ranged from 0.69 to 21.69 mg ha^-1, respectively. To sustain and improve soil fertility, a comprehensive approach is recommended, combining the use of bio-fertilizers, organic manures, and appropriate combinations of chemical fertilizers. This integrated approach ensures the replenishment of essential nutrients in the soil, promoting healthy crop growth and yield.
