Description: Das Projekt "Untersuchung der Wirkung von Saeureablagerung durch Manipulation von Waldoekosystemen" wird vom Umweltbundesamt gefördert und von Universität Göttingen, Institut für Bodenkunde und Waldernährung durchgeführt. Objective: To quantify the effects of adverse soil conditions caused by acid atmospheric deposition on forest ecosystems. General information: the research will be done at fives sites with different atmospheric and ecological conditions using soil manipulation, and collecting the same set of parameters. At each of the sites, plots will be established with a range of soil chemical conditions for tree growth in existing sites, by various methods: fertigation to arrive at optimal soil chemical conditions for tree growth (Netherlands; Denmark; sannarp, w Sweden; vindeln, n Sweden), liming and fertilization (Hoeglwald, BRD; Swedish sites), experimental acidification (Hoeglwald, BRD), and water- and nutrient removal (Solling, BRD). At each site, tree growth and nutrient cycling (including nutrient mineralization and immobilization) will be measured. There will be full data exchange so that each research group can apply its particular models to all sites, while specialized activities will be done at all sites by the partner best specialized for the job. An extension is foreseen to study the carbon balance of trees, and to quantify the effect of ambient and clean (filtered) air under various (adverse and improved) soil chemical condition pertaining to acid atmosphere by gas exchange studies using mobile equipment.
