Role of atmospheric sulfate from industrial gypsum emissions in shaping soil solution chemistry and aluminum speciation along the soil profile
Abstract
, indicating vertical redistribution driven by water fluxes. PCA identified sulfate as the primary variable governing the organization of soil solution chemistry along the soil profile. Overall, these findings demonstrate that continuous atmospheric sulfate deposition from industrial activities can induce processes analogous to those observed in soils amended with high rates of agricultural gypsum, with important implications for nutrient dynamics, aluminum availability, and the environmental quality of tropical soils.
