| Abstract |
A two-component soil water flow model was used with an equilibrium speciation model WATEQF to study aluminum mobility in soils of a forested watershed. Analysis of soil solution samples showed that aluminum concentrations decreased with depth. All waters contained acid-soluble aluminum and exhibited a negative correlation between pH and the inorganic monomeric aluminum concentrations. Water in the shallow soil showed different chemical compositions for the two flow types, while C horizon micropore and macropore waters were similar. Because of its shorter residence time, water flowing in deep soil macropores underwent less extensive neutralization and immobilization of aqueous aluminum than micropore water. |
