Abstract A freshwater wetland at the Experimental Lakes Area in northwestern Ontario stored most of the SO4 2− received annually from precipitation, runoff and experimental additions. The S budget was determined for a small fen spray irrigated with H2SO4 and HNO3. Annual S retention was greatest during the first year of experimental addition of H2SO4 (73% of input in 1983). Retention was lowest (22%) in 1984, a year of lower than average precipitation with a long hot summer. During years with hot, dry summers, SO4 2− was produced from the reoxidation of reduced S compounds in the peat and released to surface waters. The autumn SO4 2− pulse was accompanied by the release of Ca and Mg but was not accompanied by a H+ release as has been detected in eastern Ontario and southern Norway, areas which receive more acidic precipitation.
