Measuring nitrogen in nature
Nitrogen is an invisible and odorless gas in the air. Although nitrogen in itself is not a problem for humans and nature, it could combine with other elements such as oxygen and hydrogen. Through this, nitrogen oxides and ammonia are formed, which can be harmful. These nitrogen compounds from agriculture, traffic and industry end up in the atmosphere and settle on the soil surface. This is called nitrogen deposition.
Researchers Shirah Buijnink and Isabella van Schothorst set up measuring equipment at 25 locations to measure nitrogen deposition. The research is conducted on the Veluwe and the Utrechtse Heuvelrug because nature reserves are vulnerable to the effects of nitrogen deposition. Excess nitrogen is harmful to plants, soil and animals and causes a decrease in biodiversity.
Nitrogen ends up in soil in one of two ways: through rain or as particles. The researchers use five different setups to measure both forms of nitrogen deposition. The measuring locations vary in distance from the Gelderse Vallei - an area with manylivestock farms that emit ammonia - to better understand how nitrogen spreads.
The results of these measurements contribute to the improvement of models that predict nitrogen deposition. This data can help policymakers take measures to reduce nitrogen emissions.
Through research of complex issues, we contribute to the preservation of nature and the welfare of man and animals.
