Improved compositions are disclosed that inhibit ammonia volatilization from poultry litter and other animal enclosures. In some variations, a composition for use in reducing ammonia 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 embodiments, the animal enclosure is a chicken house. The ammonia concentration may be maintained below 50 ppm NH3, preferably below about 25 ppm NH3. L'invention concerne des compositions améliorées qui inhibent la volatilisation ammoniacale provenant de la litière de volaille et autres compartiments pour animaux. Dans certaines variantes, une composition destinée à être utilisée dans la réduction de la production d'ammoniac dans des compartiments pour animaux comprend du sulfate de métal, un acide organique ayant un pKa d'environ 3 ou plus, et éventuellement un tampon. Dans certaines variantes, une composition destinée à être utilisée dans la réduction de la production d'ammoniac dans des compartiments pour animaux comprend du sulfate de métal, un acide inorganique ayant un pKa d'environ 1 ou plus, et un tampon. Un procédé permettant de réduire la concentration d'ammoniac dans un compartiment pour animal (par exemple, un poulailler) consiste à introduire l'une quelconque des compositions décrites ici. Dans certains modes de réalisation, le compartiment pour animal est un poulailler. La concentration d'ammoniac peut être maintenue en-dessous de 50 ppm NH3, de préférence en-dessous d'environ 25 ppm NH3.
