ABSTRACT:
Short term control of ammonia volatilization from animal manures is provided by surface treatment with aluminum sulfate. The aluminum sulfate may be applied to manure or manure receiving surfaces in an animal rearing facility in solid or liquid form. The control of atmospheric ammonia levels in animal rearing facilities to preferably less than about 25 ppm ammonia can be achieved by surface treatment employing amounts of alum as low as 0.5% by weight alum based on manure present.
