The Nitrogen Underground

July 2013
Discover;Jul/Aug2013, Vol. 34 Issue 6, p30
The article looks at the study of nitrogen in ecological systems, as of 2013. It notes the problem of water pollution from nitrogen-based agricultural fertilizers and discusses research being conducted by ecologist Martin Burger and colleagues, who are attempting to trace the path of nitrates from fertilizer through soil layers and relate it to the nitrogen-fixing properties of various crops.
