Ammonia Emission Control for Liquid Manure Storage Practices

In the air, ammonia can combine with other gases to form ammonium nitrate and ammonium sulfate, which are fine particulates. These particulates are of concern for human health and are regulated under the Clean Air Act. Therefore, minimizing the release of ammonia from animal feeding operations is desirable. Similar to housing strategies, strategies to reduce ammonia from manure storage focus primarily on preventing ammonia formation and volatilization or downwind transmission of ammonia, after it is volatilized. A list of practices to reduce ammonia from manure storage facilities is provided below.

• Impermeable Covers
• Permeable Covers
• Urine-feces Segregation
• Acidification
• Manure Additives
• Landscaping
• Diet Manipulation
