Sustainable soil management is essential for maintaining soil health properly for future production. A comparative study was carried out in Dumuria upazila under Khulna district to observe the current fertility and physical changes of soils over the period of time due to different land use. In physical analysis: Soil Texture, Soil Structure, Bulk Density, Total Porosity and in chemical analysis: Nitrogen (N), Phosphorous (P), Potassium (K), Sulfur (S), Soil Organic Matter (SOM), Soil Organic Carbon (SOC) along with CEC, SAR, ESP, BSP, %Salt were determined. Except control, all soils were shown silt loam in texture. Moisture percentage of soil varied between 11.57±0.49 to 2.57±0.32 and all soil indicated good porous soil (average 47±5.59). Soil pH (5.96 to 7.4) indicated that soils are neutral to alkaline in nature and average (0.11±0.05)% salts were present. SOM was higher in natural vegetative soil (2.45±0.46) % and decreased over the period of land use for cultivation. In terms of ESP and SAR, sample C showed the highest value and a significant difference was observed among the treatments (p ≤ 0.05). In BSP, sample B showed the highest value and sample E showed the lowest value and statistically insignificant among treatment (p ≤ 0.05). Overall observation showed that long term land use reveals a significant decline of soil quality. So, sustainable soil management should be incorporated towards the development of suitable agricultural management such as use of organic matter or incorporate organic mix inorganic fertilizer and adaptation of soil conservation farming. Therefore, proper strategies should be taken to seek a sustainable solution that better addresses of soil fertility management.
