USDA Scientists Find Answers to How Dairy Farms Contribute to Greenhouse Gas Emissions
Idaho research is first detailed study on emissions from large-scale dairies.
The results indicated that, on average, the facility generated 3,575 pounds of ammonia, 33,092 pounds of methane and 409 pounds of nitrous oxide every day. The open lot areas generated 78 percent of the facility's ammonia, 57 percent of its nitrous oxide and 74 percent of the facility's methane emissions during the spring.
