Short summary

This study describes and evaluates a new ammonia (NH₃) exchange model for grazed fields (GAG_field). GAG_field is able to simulate the main features of the observed NH₃ fluxes. A sensitivity analysis for the non-meteorological model parameters showed that the sensitivity of the NH₃ fluxes to a parameter varies among urine patches. Moreover, the fluxes modelled with a dynamic soil pH are similar if a constant pH 7.5 is used, suggesting a useful simplification for regional-scale model application.
