Solute Fluxes and Sulfur Cycling in Forested Catchments in SW Germany as Influenced by Experimental orest (SW Germany) and effects of experimental (NH.).SO. additions. The interaction of the terrestrial and aquatic system is assessed using an integrated approach which combines flux measurements in representative plots on the stand level with input-output budgets of small catchments. The approach,

Stream Chemistry Impacts of Conifer Harvesting in Welsh Catchmentsgelert, Wales, UK. Felling resulted in rapid increases in NO. and K. concentrations at both sites. A maximum of 3. 2 mg N L. was observed at Plynlimon about one year after the start of felling. Concentrations declined to control stream values (0. 5 mg N L .) after 5 years. At Beddgelert, NO. concent

Retention and Mobility of Cations in a Small Peatland: Trends and Mechanismss, ion exchange and accretion in biomass are the major internal processes governing cation accumulation in peatlands. It is widely believed that peatlands have a large capacity to store cations, and thus to affect the acidity of surface waters. A long-term record of hydrologic and chemical inputs an

Transformation of Simulated Wet Sulfate Deposition in Forest Soils Assessed by a Core Experiment Usi a period of 20 months, core lysimeters of five acidic forest soils from Southern Germany with different parent material and pedogenesis were irrigated with solutions chemically similar to canopy throughfall. Sulfate deposition in three experimental variants corresponded to 23, 42 and 87 kg S ha. yr
