Nitrogen, one of the most plentiful gases in our environment, is both a friend and foe to our planet and to ourselves.

It makes up 45% of the nutrients used in fertilizers to grow corn, wheat, and soybeans.  That’s why it is essential to crop output. However, nitrogen can be a pollutant – especially when it seeps into water supplies through agricultural run-off or leaching.

Researchers have been exploring various techniques to reduce the nitrogen that ends up in lakes, streams, and other bodies of water.
