Short summary

Climate change enhances the occurrence of summer droughts and heavy rainfall events in Central Europe. We investigated the response of inorganic nitrogen cycling, redox conditions and microbial community composition to an artificial heavy rain event following a drought in shallow arable soil. Redox conditions changed fast with the hydraulic event triggering nitrogen transport and turnover. Microbial communities remained rather stable in terms of composition but exhibited enzyme activity changes.
