Nitrogen deposition – at what point is it too much for tree growth?

Publication in Wald & Holz (in German)

Nitrogen is a nutrient that would naturally be in short supply in most forests. Today, however, a lot of reactive nitrogen is carried in the air from agriculture, industry and traffic. However, too much nitrogen can also be harmful. We ask: What is the optimum for forest growth, and at what point is it too much for which tree species? The latest results from the Swiss monitoring network TreeNet as well as results from European studies provide answers.
