- Abstract
The article discusses the effects of atmospheric nitrogen (N) deposition on ecosystems and the empirical N critical loads in the U.S. The ecosystem impacts include biogeochemical responses which involve increased N mineralization and nitrification, and individual species, population and community responses which involve increased tissue N and changes in species richness. It is noted that the empirical critical loads for N increase in life forms including diatoms, lichens and trees.
