Short summary

Field-applied animal slurry is a significant source of NH₃ emission. A new system of dynamic flux chambers for NH₃ measurements was developed and validated using three field trials in order to assess the variability after application with a trailing hose at different scales: manual (handheld) application, a 3 m slurry boom, and a 30 m slurry boom. The system facilitates NH₃ emission measurement with replication after both manual and farm-scale slurry application with relatively high precision.
