N2O exchanges by three agricultural plots in Southern Belgium: Dynamics and response to meteorological drivers and agricultural practices. ; Echanges de N2O sur trois sites agricoles en Wallonie : dynamiques et réponse aux sollicitations météorologiques et aux pratiques agricoles.

In Belgium, managed soils are responsible for more than 60 % of N2O emissions from agriculture. This thesis aimed at gaining insight on the influence of farming practices and meteorological conditions on N2O emissions and flux dynamics in crops and grassland in Belgium. We worked on three research focus points: (1) the suitability of eddy covariance to measure N2O fluxes, (2) the influence of farming practices on N2O exchanges and (3) the weight of N2O in the greenhouse gas budget of managed soils. Three measurement campaigns were setup in Southern Belgium. In 2015, two sets of automated dynam... Mehr ...
