Theme III. Agricultural use of peat and peatlands
SUMMARY
In this study, we aim to quantify dry atmospheric nitrogen (N) deposition at a semi-natural peat bog site. First results show ammonia (NH3) being the site’s most important reactive N species on a quantity basis. Ammonia concentrations range from 0.9 to 13.0 μg m-3. Based on these results, we found a total dry N deposition of about 5 kg ha-1 during the first eight months of the experiment. Extrapolation of data to one year amounts approximately to 9 kg ha-1 yr-1.
Our results suggest that the intensive agricultural practices of surrounding areas most likely leads to increasing N input into the bog and a shift in both vegetation composition and local hydrology is expected.
