- •
We compared N budgets for soils from an ombrotrophic bog and a minerotrophic fen.
- •
Soil N content depended on location within the bog or fen, and on soil depth.
- •
We highlight the importance of biogeochemical hotspots within the peatlands.
- •
We show the importance of organic N storage, as a source of N for denitrification.
- •
We propose a link between N storage, denitrification and N export from peatlands.
