| Description: |
Nitrogen lost to the environment from agricultural fields is nitrogen not used by crops. It costs farmers money and degrades water and air quality, with significant health, biodiversity and downstream economic effects. Researchers are working on a way to help make the time and expense of efforts to mitigate fertilizer loss worthwhile. They're putting the finishing touches on a program that would pay farmers to apply less nitrogen fertilizer in a way that doesn't jeopardize yields. The program is called the nitrous oxide greenhouse gas reduction methodology. [Source: National Science Foundation]
