An assessment of chemical properties of soil in Chaka block Prayagraj, Uttar Pradesh was carried out in 2019-20. Six sampling points in different villages were selected for the analysis. Soil samples were collected at depths of 0-15, 15-30 and 30-45 cm. The chemical properties found in this region are varied from place to place. The study revealed that range of pH from 7.05 to 7.69, EC range from 0.19 to 0.45 dS m -1 , organic carbon range from 0.43 to 0.56 %, organic matter range from 0.73 to 0.96 %, nitrogen range from 279 to 260 kg ha -1 , phosphorus range from 15.11 to 18.12 kg ha -1 , potassium range from 150.22 to 225.21 kg ha -1 . The sulphur range from 8.00 to 11.80 kg ha -1 ; during the course of investigation responded appropriate chemical properties which were suitable of crops production in Chaka block of Prayagraj. K e y w o r d sChemical properties of soil Chaka, Prayagraj, etc.

The sampling location was Saharsa, which is one of Bihar's most flood-prone area Flooding is the leading source of soil degradation in the district. The current study was carried out in the Soil Science and Agricultural Chemistry laboratory at Sam Higginbottom University of Agriculture Technology and Sciences. 27 samples were collected from several farmer's fields, and composite sampling was carried out from three depths of 0-15, 15-30, and 30-45 cm. The results revealed that the texture was sandy loam to sandy clay, bulk density ranged from 1.11 to 1.59 Mg/m3, particle density ranged from 2.22 to 2.85 Mg/m3, pore space ranged from 52.60 to 66.50 % and water holding capacity ranged from 61.11 to 78.12 %. The pH ranged from 6.58 to 7.65, E.C. from 0.17 to 0.39 dS/m,(Due to Flooding) Soil Organic Carbon ranged from 0.74 to 1.20 %, Soil has acceptable Bd, Pd, pore space, and water holding capacity. As a result of the beneficial electrical conductivity for plants, the pH of the soil is neutral to alkaline. Sodium is low to medium in range. Low to medium levels of macronutrients are found in nitrogen, phosphorus, potassium, calcium, magnesium, and sulphur. By employing the proper management techniques and supplying the soil with enough nourishment for plant growth, farmers must maintain the health of their soil.
