Turf’s Dirty Little Secret – Eos

Australian scientists have found that grassy sports fields used for soccer, cricket, and baseball can release a potent greenhouse gas into the environment. A yearlong study at La Trobe University in Melbourne, Vic., suggests that mowing, fertilizing, and applying herbicides to turfgrass sports fields contribute to the release of large amounts of nitrous oxide.

“This study is another indication that urbanization has complex impacts on our environment,” said Amy Townsend-Small, a biogeochemist who was not involved with the research. “Even though most cities are working toward increasing their amount of green space, this doesn’t always help meet climate goals.”
