Impact of nitrogen (N) deposition was studied by comparing N fluxes, N concentrations and
N pool sizes in vegetation and soil in five coniferous forest stands at the NITREX sites …

In view of growing environmental concern and stringent legis-lation, there is a critical need
for environmental considerations in the developing large-scale chemical processes. The …

European concern over the cause and consequences of forest decline, acidification of soils
and surface waters, and the nutrient enrichment of terrestrial and aquatic ecosystems, led to …

Enhancement of the atmospheric N deposition is a serious threat for the structure and
function of ecosystems. Here we evaluate the ecological effects of excess N with respect to …

To investigate which ecosystem parameters determine the risk and magnitude of nitrate
leaching we compiled data from published and unpublished sources on dissolved inorganic …

As part of four European ecosystem manipulation experiments in coniferous forests, field-
scale 15N tracer experiments have been carried out. The experiments involved a year-long …

The fate and effects of increased N deposition were investigated by experimental
manipulation in a mature Norway spruce plantation at Klosterhede, western Denmark. The …

In a highly N-saturated Scots pine stand atmospheric N input to the forest floor was reduced
to pre-industrial levels by means of a transparent roof and application of clean, artificial …

Nitrogen (N) deposition exceeds the critical loads for this element in most parts of
Switzerland apart from the Alps. At 17 sites (8 broadleaved stands, 8 coniferous stands, and …

The effect of changes in dissolved inorganic nitrogen (N) deposition on ecosystem
functioning was investigated in the NITREX (NITRogen saturation EXperiments) project …
