Implementation of the effect of urease inhibitor on ammonia emissions following urea-based fertilizer application at a Zea mays field in central Illinois: A study with SURFATM-NH3 model

•Modeling the bi-directional NH3 exchange at the field scale using SURFATM-NH3.•Integrating an operational parameterization of emission potentials in the model.•Parameterizing the effect of urease inhibitor on NH3 volatilization.•Satisfactory simulations of NH3 fluxes by integrating the effect of urease inhibitor.•Good predictions of dynamic and order of magnitude of emission potentials by the model.
