Format: Oral Topical Session
Keywords: denitrification, modeling, reactive nitrogen and scaling
Session Description: Denitrification is the key process returning reactive nitrogen to the atmosphere. Despite being intensively studied for more than 100 years, soil denitrification rates and emissions of its gaseous products can still not be satisfactorily predicted. The complexity of the process in response to highly temporally and spatially variable soil properties (matrix to field scale) prevents robust prediction of denitrification rates and gaseous emissions. This symposium will combine studies on interactions between effects of key factors on denitrification and its gaseous emissions, and modelling of these processes at scales from matrix to field will be addressed.
