CSU gets funding to study feedlot emissions

Colorado State University researchers have received $1.15 million in federal funds to study how much nitrogen and ammonia are emitted from cattle feedlots.

Feedlots along Colorado's Front Range are believed to be a major source of nitrogen pollution in Rocky Mountain National Park to the west. Biologists say the park's rising nitrogen levels could lead to fish die-offs and other environmental harm.

The money from the U.S. Department of Agriculture will fund three projects, led by Colorado State's Institute for Livestock and the Environment. Researchers will measure ammonia and other pollutants from feedlots and evaluate influences on emission levels, such as weather, the animals' diet and the handling of manure.

Feedlots along the Front Range can handle a total of about 600,000 cattle.
