The objectives of this study were to measure NH<jats:sub>3<\/jats:sub> volatilization losses during composting of poultry layer manure, and to evaluate the potential of different amendments to reduce NH<jats:sub>3<\/jats:sub> losses using a laboratory composting simulator. The poultry manure was treated with various amendments which included two natural zeolites, clay, coir (mesocarp of coconut fruit), CaCl<jats:sub>2<\/jats:sub>, CaSO<jats:sub>4<\/jats:sub>, MgCl<jats:sub>2<\/jats:sub>, MgSO<jats:sub>4<\/jats:sub>, and Al<jats:sub>2<\/jats:sub>(SO<jats:sub>4<\/jats:sub>)<jats:sub>3<\/jats:sub>. The manure was composted for 49 to 56 d. Ammonia volatilized from the manure was trapped in a 0.3 <jats:italic>M<\/jats:italic> H<jats:sub>2<\/jats:sub>SO<jats:sub>4<\/jats:sub> solution. The composts were weighed and analyzed for moisture content, total N and NH<jats:sup>+<\/jats:sup><jats:sub>4<\/jats:sub>. The NH<jats:sub>3<\/jats:sub> volatilization loss for the unamended manures ranged from 47 to 62% of the total manure N. A layer of 38% zeolite placed on the surface of the manure reduced NH<jats:sub>3<\/jats:sub> losses by 44%, whereas 33% coir placed on the surface of the manure reduced NH<jats:sub>3<\/jats:sub> losses by 49%. The 20% alum treatment reduced NH<jats:sub>3<\/jats:sub> losses by 28%. Composting poultry manure with zeolites, coir, and alum produced composts with high NH<jats:sup>+<\/jats:sup><jats:sub>4<\/jats:sub> concentrations ranging from 17 to 53% of total N. The addition of 20% CaCl<jats:sub>2<\/jats:sub> to poultry manure decreased NH<jats:sub>3<\/jats:sub> volatilization but did not result in increased NH<jats:sup>+<\/jats:sup><jats:sub>4<\/jats:sub> or NO<jats:sup>\u2212<\/jats:sup><jats:sub>3<\/jats:sub> concentrations. The 38% zeolite Z1 and 33% coir\u2010treated composts had total N concentrations of 17 and 31 g kg<jats:sup>\u22121<\/jats:sup>, respectively. The zeolite and coir amendments were proposed to be the most suitable for reducing NH<jats:sub>3<\/jats:sub> losses during composting of poultry manure.<\/jats:p>","DOI":"10.2134\/jeq1999.00472425002800010023x","type":"journal-article","created":{"date-parts":[[2010,7,20]],"date-time":"2010-07-20T10:28:51Z","timestamp":1279621731000},"page":"194-201","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":117,"title":["Reducing Nitrogen Losses during Simulated Composting of Poultry Manure using Adsorbents or Chemical Amendments"],"prefix":"10.1002","volume":"28","author":[{"given":"M.","family":"Kithome","sequence":"first","affiliation":[{"name":"Agriculture and Agri\u2010Food Canada Pacific Agri\u2010Food Research Centre P.O.
