In Taiwan, the average sulfate and nitrate deposited by acid rain as precipitation amount to 50 kg SO 42− and 15–50 kg NO 3− ha −1 year −1 , respectively. The reactions of sulfate and nitrate with forest soils were not fully understood. Thus, we selected two forest pedons, namely the Dystrochrept and Hapludult of the Lien-Hua-Chi watershed in central Taiwan,...
Two forest soils (Typic Hapludult and Typic Haplorthod), on A-Li Mountain, central Taiwan were selected for this study. Soil physical and chemical properties, clay mineral compositions, and characteristics of layer charge were investigated. The amount and composition of their interlayer materials were studied by sodium citrate extraction in combination with X-ray diffraction (XRD) analysis. High soil...
