28TH EUROPEAN NITROGEN CYCLE MEETING

8.–11. September 2025, Vienna

We are excited to welcome you to the 28th European Nitrogen Cycle meeting (ENC28), hosted at the University Biology Building in Vienna from September 8-11, 2025.

As human activities have almost doubled the flux through the nitrogen cycle, deeper understanding of the organisms and processes involved in this key biogeochemical cycle is essential to shape a sustainable future. To this end, ENC28 will bring together scientists from across Europe (and beyond) to explore and discuss the many aspects of the nitrogen cycle, including biochemistry, microbial physiology, and structural biology, as well as the global impact of nitrogen cycle processes through the lens of biogeochemistry and modelling.

We hope you will enjoy the scientific and the social program, both aimed at scientific exchange and fostering ongoing and future collaborative work, and that ENC28 will give you an unforgettable stay in beautiful Vienna.
