摘要

•Eddy covariance was used to quantify NH3 emission during two slurry spreading.•Inverse modelling was used for validating data obtained by Eddy covariance.•NH3 volatilisation decreases within 24h from slurry spreading.•NH3 volatilisation stopped after slurry soil incorporation.•The total losses of NH4+-N were 19.4% and 28.5%, within 7 days after the spreading.
