A year-long experiment, using reconstructed spodosol and intact alfisol soil columns, was conducted to examine the effects of various simulated throughfall solutions on soil C dynamics. Soil organic C solubilization, dissolved organic C fractions, and decomposition rates were studied using simulated acidic and salt throughfall solutions. Based on the results of the study the authors propose that throughfall solutions of pH above 3.7 will have little or no influences on dissolved organic C cycling in the types of spodosol and alfisol forest soils used here. However, at pH 3.0 some alterations in organic C solubilization, dissolved organic C fractions, and mobility could be expected.
