Information on soil physical and chemical properties is vital for the major crop production. This information is largely absent in the south-central coastal saline and non-saline region of Bangladesh. This study evaluated the soil properties of 18 surface soil samples (15 cm depth) from various zones in Bamna upazila (sub-district) of the study area. All soil samples were air-dried, separated, and analyzed for multiple fertility indicators, including physical characteristics and chemical properties using standard analytical methods. The fertility of the soil was assessed by computing the nutrient value index. The findings indicated that the average values for pH, EC, NaCl, Cl-, organic carbon, organic matter, total nitrogen, available sulfur, available phosphorus, and exchangeable potassium across all soil samples were 6.24, 6.87 dS m⁻¹, 2.63%, 668.85 ppm, 1.20%, 2.08%, 0.19 %, 46.13ppm, 25.17ppm, and 0.2606meq/100g, respectively. Most of the chemical properties were found to be in a suitable range for crop production. Approximately 68.91% of the soils were classified as silt, 23.77% as clay, and the remaining as sandy. Moisture content, particle density, bulk density, and porosity were measured at 25.26%, 2.45gcm-³, 1.40gcm-³ and 42.73% respectively. The findings from this research will aid stakeholders and local authorities in executing effective strategies for major crop production.
