Short summary
Peatlands have been exposed to nitrogen (N) deposition in Europe for decades. In this greenhouse study we investigated how N concentration and mobility in plants and peat have responded by sampling five sites across Europe and experimentally depositing labeled nitrogen on samples in a greenhouse. The peat moss retained its ability to absorb labeled nitrogen, but in the polluted sites more of it reached the deeper peat and was taken up by shrubs and grasses, indicating increased mobility of N.
