Johnson, D W; Lindberg, S E

The forest effects research is divided into two major sections: atmospheric deposition and forest nutrient dynamics. Atmospheric deposition tasks will provide estimates of the rates of deposition to the canopy by precipitation, dry deposition of vapors and particles, and by cloud and fog interception, and also the wetfall return to the forest floor. The forest nutrient effects tasks will provide estimates of element fluxes in litter and soil systems, estimates of internal H/sup +/ production, and characterization of key processes leading to S, N, and H saturation in soils. The results of these tasks will be combined in assessments of atmospheric deposition effects on forest nutrient cycles, which can in turn be applied to assessments of nutritional causes of forest dieback and long-term effects on productivity.
