Brick kilns have a major negative influence on the environment, which in turn has an adverse effect on agricultural productivity. In comparison to soils located farther away, the productivity of the land surrounding brick kilns is much lower. The purpose of this research is to ascertain the influence that the operation of brick kilns has on the deterioration of the soil quality in a variety of places within the Barishal Sadar Upazila. A total of 20 samples were selected at random from ten distinct locations within the research site. According to the findings of the research, industrial activities related to brick kilns negatively influenced the soil's physical and chemical properties, hence lowering the soil's quality. The findings demonstrated that the pH values of soils in both the surface and the subsurface were dramatically lowered after being subjected to a burning process. The organic matter content of the samples observed from 0.259 to 0.923 percent in the burnt soil and from 0.287 to 1.077 percent in the unburned soil for surface soil. For subsurface soil, the organic matter content was observed to range from 0.190 to 0.635% and 0.184 to 0.630% in the burnt and unburned soil respectively. The total nitrogen concentration of the surface soil varied from 0.022 to 0.100 percent in burnt soil and from 0.027 to 0.12 percent in unburnt soil, respectively. In the case of subsurface soil, the nitrogen concentration varied from 0.036 to 0.061% in burnt soil and from 0.039 to 0.066% in unburnt soil. The accessible phosphorus level of the surface soil samples ranged from 9.89 to 19.16 ppm in the soil that had been burnt, whereas it was in the range of 17.46 to 21.95 ppm in the soil that had not been burnt. The range for unburned subsurface soil was from 11.20 to 19.21 ppm, while the range for burnt subsurface soil was from 8.64 to 13.16 ppm. For surface soil, the EC of burnt soil varied from 9.7 to 25.3 ds/m, while for subsurface soil, the EC ranged from 5.2 to 12.2 ds/m. For the unburnt soil next to brickfield, the electrical conductivity values ranged from 13.3 to 27.7 for the surface soil and from 8.3 to 24.3 for the subsurface soil. All of the soil's chemical attributes were lower in the burnt soil from the brick kiln as compared to the soil from the unburned agricultural area. Increasing depth also degraded chemical properties. According to the findings of the research, brick burning in close proximity to agricultural fields has a negative impact on soil fertility. The combustion of vast amounts of carbon, nitrogen, and sulfur not only degrades the soils used for agricultural production but also contributes to shifts in the world climate.
