Abstract in another language

Above-ground deposition of anthropogenic trace gases like NH3 and NOx is considered as a main factor for nitrogen (N) loading of Picea abies ecosystems. In order to quantify NH3 deposition, tracer experiments with 15N labelled NH3 were carried out in fumigation chambers (GSF Munchen).NH3 uptake is linearly related to the gas concentration in the air, but the relation differs between organs and depends on N-nutrition of the organs. Plants well supplied with N have a lower NH3 uptake per g dry weight then plants deprived of N. Only a small amount of the offered gas deposits to the external plant surfaces. The NH3 uptake rates of spruce indicate that NH3 may be regarded as being just as or even more important as environmental pollutant than NOx with respect to N loading of spruce ecosystems.
