Description:
There has been considerable advancement in the understanding of the S biogeochemistry of forested ecosystems. any recent studies have focused on ascertaining the impacts of acidic deposition of forest vegetation, soils and surface waters. ulfur dynamics effects the flux of both H+ and SO42- both of which interact with other elemental cycles especially N and basic cations. here is extensive information on the S constituents and fluxes for temperate forest ecosystems, but little for tropical areas. hese latter areas may be particularly important contributors to trace S gases in the troposphere. n regional as well as global scales, forest ecosystems are being subjected to changes in atmospheric loadings of S as well as other anthropogenic effects including deforestation and climatic alterations. redicting how these changes will be, affect both organic and inorganic S pools of forest ecosystems and how these alterations will influence gaseous and leaching losses should be the general focus of future research on S biogeochemistry.
