The summaries contained in this report describe the trends in atmospheric deposition, canopy interactions, soil solution fluxes, and ecosystem budgets for the major chemical species studies in the Integrated Forest Study (IFS). This document also includes summary reports of each supportive deposition and soils experimental task, and descriptions of specific field research performed at each site. This report is one of a series of reports on the IFS, including Site Descriptions, Measurement Protocols, and Project Summary. Preliminary analysis of the deposition and nutrient cycling data indicated several interesting trends across sites. The deposition estimates confirm the expected increase in atmospheric deposition at high elevation sites compared to lower elevation forests. Input to the Smoky Mountains site in the Southeast exceeded that to all other sites for most chemical species. Cloudwater interception, enhanced dry deposition due to high wind speeds, and increased rainfall due to orographic effects all contribute to this trend. At the other sites dry deposition was important in the input of all ions, particularly at the dryer southeastern sites and most significantly for the base cations. Canopy interactions were minimal for deposited Na and S, but indicated significant canopy absorption of strong acidity and N, and foliar leaching of base cations at all forests.
