Abstract
Sulfate leaching was studied in the laboratory in undistributed Ando soil cores comprising I A, I B, and II A horizons that were taken in a Japanese cedar forest. The soil cores were watered with 0.4 me.l-1 sulfuric acid solution having pH 3.0. The sulfate concentration of the leachate remained at about 0.05 me.l-1 at pH 4.1 to 4.2, but after 15l sulfuric acid solution was applied, SO42- leaching was accelerated at pH 3.9 to 4.0. The stability diagram showed a better fit with gibbsite. In the I A horizon, which did not accumulate SO42, the soil pH was 3.1. SO42- accumulation had occurred in both the I B and II A horizons. The adsorption maximum was about 4.0 me · 0.1 kg-1.
