Abstract

Several studies have indicated a long-term decrease in exchangeable Ca in forest soils within the northeastern Unrted States, but the regional extent of these decreases and the importance of acid deposition as a cause has not been fully resolved. Results, from two recently completed studies have provided the opportunity to further investigate the role of acid deposition in depletion of base cations in northeastern forest soils. These two studies entailed 1) a survey of soils in northeastern red spruce (Picea rubens Sarg.) stands, whtch were selected to encompass the range of environmental conditions to which this species is subjected, and 2) a study of base-cation leaching in soiis of a hardwood watershed in the Catskill Mountains of New York.
