Quantifying aboveground N uptake from wet deposition: effect of tree species, N load and leaf phenology

Abstract
Semi-natural ecosystems such as forests are exposed to higher inputs of atmospheric pollutants originating from anthropogenic sources. This increased deposition has caused changes in biogeochemical processes, which may have adverse effects on forest structure and functioning. Therefore, an accurate quantification of total atmospheric deposition is required. One widely known technique is the throughfall method, in which the amount and quality of water above and beneath the canopy are compared. Total atmospheric deposition is then quantified by a so-called canopy budget model (Draaijers and Erisman, 1995), which estimates ion-exchange reactions between the canopy and throughfall water. Although this model is applied worldwide, it has rarely been validated (Staelens et al., 2008), and dry deposition and canopy exchange of nitrogen (N) generally cannot be quantified accurately from throughfall measurements. Therefore, this study focused on the assessment of aboveground N uptake from wet deposition, which can be quantified directly by the application of 15N labelled sources. A better understanding of the direct aboveground N uptake by different tree species under varying N pollution levels may lead to an improved canopy budget model.
