Responses of Forest Ecosystems to Changing Sulfur Inputs

Abstract

There was little information on sulfur (S) cycling in forests compared with that of other nutrients (especially N) until the past two decades. Interest in S nutrition and cycling in forests was heightened with the discovery of deficiencies in some unpolluted regions (Kelly and Lambert, 1972; Humphreys et al., 1975; Turner et al., 1977, 1980) and excesses associated with acidic deposition in other regions of the world (Mewies and Khanna, 1981; Shriner and Henderson, 1978; Johnson et al., 1982, 1986b). Several reviews have been written about S cycling in forests, and the interested reader should refer to those papers for a general treatise on the subject (Turner and Lambert, 1980; Johnson, 1984; Mitchell et al.. 1992a,b). It is our primary purpose to consider an important but often overlooked aspect of S cycling in forests-namely, the response to changing S inputs.
