What is manure removal?

Frequent manure removal is an efficient way of reducing contaminant generation within the building. Other methods that can be used inside buildings include using bedded solid manure (i.e., manure mixed with bedding that creates a solid stack of material), chemical additives on animal litter, and diet manipulation.


How does ammonia affect the environment?

Ammonia has a direct, toxic effect on vegetation. When returned to the soil and water by rainfall, it disrupts ecosystems causing algae bloom in water bodies and acidification of soils. It is estimated that emissions from animal waste account for about one-half of the ammonia emitted in the United States annually.
