Cronan, C S

The goal is to establish an experimental framework within an intact forest ecosystem that permits the examination of plant-soil functional responses to acid precipitation. Specific objectives include: (1) the determination of whether element leaching from forest soils under current conditions of acid deposition is markedly different from the historical leaching pattern; (2) a comparison of the intrinsic annual rate of acid generation in forest soils with the annual deposition flux of strong acids from the atmosphere; and (3) the determination of whether current conditions of acid deposition have altered any of the important properties or processes of the whole plant-1 soil system. Progress to date includes construction and debugging of the field plot experiment. (AER)
