Assessment of Physical and Chemical Properties of Soils at Gournadi Upazila under Barisal District

The soil samples were taken in Bangladesh's Gournadi Upazila, in the Barishal district. The soils were tested for texture, pH, EC, N, P, K, S, and Na in order to evaluate the qualitative analysis of some basic plant nutrients in agricultural soil and to assess crop suitability. In Gournadi Upazila, the texture groups were silt loam. The sand fractions ranged from 13.25 percent to 26.25 percent. Silt fractions ranged from 44.7% to 77.5 percent, while clay fractions ranged from 10.25 to 29.5%. Gournadi's soil pH ranged from 7.16 to 8.72. This zone's soil is virtually alkaline. The degree of salinity can be determined by measuring electrical conductivity.The soils had EC values ranging from 0.09 to 0.24 dS/m, indicating that they were not saline. Gournadi's total nitrogen content ranged from 0.028 to 0.74 percent. At this Upazilla, the average total N content was 0.11 percent. The total volume of nitrogen in maximum locations was at its maximum. This may be attributed to the addition of a lot of organic matter, as well as the fact that there is still a lot of crop residue in the field. In Gournadi, the sum of available P ranged from 9.25 to 24.11 ppm. In this space, the average amount of available P was 16.72ppm. Gournadi's Exchangeable K ranged from 0.13-0.36 me/100 g soils. Gournadi's accessible S content ranged from 14.16 to 24.18 ppm.The average available S concentration was 18.65 ppm. The concentration of Na+ varied between 0.19 and 1.07 percent. The sodium concentration was found to be 0.45 percent on average. It can be concluded that the majority of the study areas' soil nutrient status is optimal, which is favourable for crop production.
