Modelling the aeolian transport of ammonia emitted from poultry farms and its deposition to a coastal waterbody

► Transport and fate of gaseous ammonia from poultry production was modelled. ► Ammonia deposition to a coastal waterbody (Pumicestone Passage) was estimated. ► Total annual deposition to the waterbody was 2.3 tonnes, comparable to other studies. ► Total annual deposition to the waterbody catchment area was 54 tonnes. ► Wet deposition accounted for 96% of all ammonia deposited in the study area.
