Abstract: A system is provided for enhancing the environment present in enclosed facilities in which livestock is being reared. The system involves the addition, periodically and in the presence of livestock, of a suitable amount of liquid ferric sulfate or ferric chloride a mixture thereof to non-diluted manure deposits on bedding material or to the livestock manure deposits on floor area where the livestock is confined. The concentration of the ferric compound in the applied liquid is sufficient to maintain a pH of about 7.5 and most preferably between 4.0 and 7.0 in the confined environment and such that it inhibits ammonia volatilization and stabilizes, i.e. insolubilizes any resulting soluble phosphorus generated.

Abstract: Liquid ferric sulfate is applied to litter, bedding or manure storage facilities in livestock and animal growing facilities for the control of ammonia, hydrogen sulfide, particulate emissions, soluble phosphorus and for animal performance improvement. Application of such materials at described rates of <50#/1000 sq. ft. to >200#/1000 sq. ft. control ammonia, odors, particulate emissions, soluble phosphorus, and improve livestock performance.
