A61L 9101  (2013.01)  (57)  ABSTRACT  Related U.S. Application Data  (60)  Provisional application No. 62/114,190, filed on Feb.  10, 2015.  Publication Classification  (51)  Int. Cl.  A61L 9101  (2006.01)  Improved compositions are disclosed that inhibit ammonia  volatilization from poultry litter and other animal enclosures.  In some variations, a composition for use in reducing ammo› nia generation in animal enclosures comprises metal sulfate,  an organic acid with pKa of about 3 or higher, and optionally  a buffer. In some variations, a composition for use in reducing  ammonia generation in animal enclosures comprises metal  sulfate, an inorganic acid with pKa of about 1 or higher, and  a buffer. A method of reducing ammonia concentration in an  animal enclosure ( e.g., a chicken house) includes introducing  any of the compositions described herein. In some embodi› ments, the animal enclosure is a chicken house. The ammonia  concentration may be maintained below 50 ppm NH$_{3}$ ,  pref› erably below about 25 ppm NH$_{3}$ •
