Max-Planck-Gesellschaft (2011, August 19). Nitrogen in the soil cleans the air. ScienceDaily Citat: "...Researchers from the Biogeochemistry Department at the Max Planck Institute for Chemistry in Mainz found out that nitrogen fertilizer indirectly strengthens the self-cleaning capacity of the atmosphere...In nitrogen-rich soils the acid is formed from nitrite ions produced through microbiological transformations of ammonium and nitrate ions...they demonstrated the existence of this previously unnoticed pathway in the nitrogen cycle...The source of the high concentrations of HONO observed in the lower atmosphere had long been a mystery..."
