| Abstract | Periods such as spring snowmelt are important for nutrient fluxes throughout the watershed and may have considerable impacts on water quality. Denitrification is an important process for reducing nitrogen (N) inputs to riparian zones, which can in turn reduce N loading to streams and rivers. However, if the denitrification process does not go to completion, greenhouse gases (GHG), such as nitrous oxide (N2O), can be emitted to the atmosphere. The research compares denitrification rates across different landscape positions (upland and wetland) within two types of riparian buffers (agricultural and forested) during the spring snowmelt period in Vermont, USA. Out results show that Hungerford has higher denitrification rates, which was expected since agricultural land can have higher soil N concentrations. Moreover, landscape position provided a more complex response, since Wade wetland was more effective within the site but, in general, Hungerford upland had higher denitrification rates. |
