Simulated sulfuric acid rain (pH 3.0, 3.5, or 4.0) or control rain (pH 5.6) was applied to decomposing leaf packs of 10 hardwood species. Changes in weight and chemical element concentrations were followed for 408 days. There was no apparent relationship between sulfuric acid rain effect on decomposition rate and initial chemical element content. Maganese was the only element whose concentration was found to depend on sulfuric acid rain treatment.
