Studies on Deposition, Emission and Chemical Transformation above and within Tall Vegetation

The exchange of inorganic and organic trace compounds in the soil-vegetation-atmosphere system is influenced by plant physiological, and physical and chemical processes in the soil and the atmosphere. A number of studies (called BIVOTEX I–V) to understand these complex interactions were performed at the Schachtenau experimental research site in the Bavarian Forest National Park, Germany [1–3]. The forest (about 86% spruce (Picea abies [L.] Karst), 14 % beech (Fagus sylvatica [L.]) has an average height of trees ≈ 28 m with LAI ≈ 5.5, crown between 14 m to 28 m, age 80–100 years, and a stand density of 721 trees/ha [1,2].
