Comparison of nitrogen and phosphorus fluxes in some European fens and floodplains

Question: How do nitrogen and phosphorus budgets and balances differ between eutrophic fens and floodplains in western Europe and fens and floodplains in Poland, where we expect less eutrophication to occur? Location: Wetlands along the rivers Dommel (The Netherlands), Zwarte Beek (Belgium) and Biebrza (NE Poland). Methods: Assessment of external input and output fluxes as well as net N-mineralization rates. Annual N- and P-balances were estimated by the sum of all external input and output fluxes: atmospheric deposition, input of dissolved matter by flooding, input of sediment by flooding, in... Mehr ...
