Funding topic 9: Reduction of emissions of reactive nitrogen compounds to environmental compartments

On the one hand, nitrogen, as a central component of protein, is one of the most important bases of life and the motor of all biological growth. On the other hand, reactive nitrogen compounds lead to complex environmental effects such as groundwater pollution with nitrate, eutrophication, release of nitrous oxide and ammonia, and negative biodiversity effects.

Exposure to reactive nitrogen compounds exceeds the safe range of planetary boundaries more than any other environmental problem. Even though nitrogen is indispensable as a nutrient, undesirable discharges into environmental compartments must be avoided as far as possible. So far, this has not been successful. For example, the nitrogen surplus in German agriculture is around 100 kg per hectare of agricultural land per year.

Action is needed to increase the efficiency of mineral and organic nitrogen fertilization and reduce losses of reactive nitrogen compounds. This is only possible with a bundle of measures that address the various sources of emissions.
