Urease- und Nitrifikationsinhibitoren für Klima- und Umweltschutz: Chance oder Risiko?

Summary

Agriculture is a major source of nitrous oxide and ammonia emissions in the EU and Germany, contributing to high nitrate levels in water and hindering climate goals. This report evaluates the potential of urease and nitrification inhibitors to reduce these agricultural emissions and nitrate leaching. While calculations suggest significant emission reductions (up to 9% ammonia, 5% GHG) with widespread use, the risks for human health and environment are insufficiently studied, and a regulatory gap exists for these substances in Germany and the EU. The German Environment Agency recommends widespread use only if a unified European regulation ensures comprehensive human health and environmental protection.
