Recent studies have demonstrated that increased available N and associated N₂O emission from soils could be moderated by alleviating phosphorus limitation. The impact of phosphorus availability on soil N transformations is directly linked to biotic (microbe and plant) responses, but the mechanisms underlying the microbial origin of N₂O emission remains unclear. Moderating excess N-loading through P-dosing requires a better understanding of the microbial sources of N₂O emission. Therefore, my research focuses on unravelling the mechanisms underlying microbial N transformation processes as influenced by phosphorus using innovative isotopic and molecular techniques.
