Urease and nitrification inhibitors are chemicals used in agriculture to increase plant nitrogen utilization of fertilizers and thereby reduce ammonia, nitrate and nitrous oxide emissions. But their application comes with environmental and health risks. The German Environment Agency (UBA) therefore recommends improved regulation of these substances.
The 8th Global Nitrogen Conference of the International Nitrogen Initiative (INI 2020) follows up on the previous nitrogen conferences that have been held since 1998. This year’s theme is “Nitrogen and the United Nations Sustainable Development Goals (SDGs)”. Most of the SDGs are closely related to the nitrogen cycle.
More than half of Germany's surface area is used for agriculture. Agriculture thus is the largest land user in Germany and a significant contributor to environmental stress. On the other hand, agriculture is also affected, for example, by the effects of climate change. In the flyer "Environment and agriculture 2018" UBA presents key facts about agriculture and environment.
Nitrogen and phosphorus are nutrients for aquatic plants (algae, macrophytes). Their high concentration causes excessive growth especially of algae (Eutrophication). Rivers transport nitrogen and phosphorus into lakes and North sea and Baltic sea and influence its nutrient concentration.
