Farm fertilizer produces greenhouse gas

Most people are aware of the “sexy” greenhouse gas CO-2. Fewer know of its co-culprit nitrous oxide. The third-largest greenhouse gas, nitrous oxide is released in soil during a natural process.

Big Ten’s Eco Efforts: University of Wisconsin

In the spirit of our “Green Gridirons” series (but just in case college football wasn’t your thing), the “Big Ten’s Eco Efforts” series highlights creative off-the-field sustainability efforts at Big Ten universities. The F.H. King organic farm at the University of Wisconsin has been growing produce for students to veg out on since 1979. The urban garden is the pride of the sustainability of agriculture program at the Madison campus. Not only does the farm donate to the school’s cafeterias to support late night food runs, but it also donates 500 pounds of produce every year to area food banks, said Meredith Keller, student programs coordinator at the university’s office of sustainability. “Our members participate in all aspects of managing a garden and either sell or hand out fruits and vegetables at locations on campus,” Keller said.
