Acidification of red pine forest soil due to acidic Deposition in chunchon, Korea

摘要

The effect of acidic deposition on the soil under red pine forest in Chunchon, Korea was investigated. Precipitation, stream water, and soil solution chemistry were monitored at the watershed from 1997 to 1998. Acidity of the open-bulk precipitation was often neutralized by large amounts of ammonia (NH_3) that might have originated from livestock farming and fertiliza- tion.
