A simulation model was developed which explained the experimental results. pH stability in response to addition of HCl, superphosphate, FeCl<jats:sub>3<\/jats:sub>, Ca(NO<jats:sub>3<\/jats:sub>)<jats:sub>2<\/jats:sub> and CaCl<jats:sub>2<\/jats:sub> in increasing levels was investigated. Upon aeration, pH rose quickly by 0.4 to 1.5 units for all additives and levels, except where HCl was added equivalently to the total alkalinity of the slurry, which then kept a stable pH of 4.2. Ammonia volatilisation in response to the addition of either HCl or CaCl<jats:sub>2<\/jats:sub> was found to decrease with increasing amount of additive, HCl being more effective than CaCl<jats:sub>2<\/jats:sub>. This confirms that the total alkalinity is an important factor regulating the potential ammonia loss from cattle slurry. Addition of HCl or CaCl<jats:sub>2<\/jats:sub> close to the total alkalinity resulted in a reduction of the potential ammonia loss to 0 and 15% of the untreated loss, respectively.<\/jats:p>","DOI":"10.1002\/jsfa.2740570305","type":"journal-article","created":{"date-parts":[[2006,10,31]],"date-time":"2006-10-31T14:38:24Z","timestamp":1162305504000},"page":"335-349","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":88,"title":["Reducing ammonia loss from cattle slurry by the use of acidifying additives: The role of the buffer system"],"prefix":"10.1002","volume":"57","author":[{"given":"S\u00f8ren","family":"Husted","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lars S","family":"Jensen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S Storgaard","family":"J\u00f8rgensen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,9,19]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.2136\/sssaj1977.03615995004100060013x"},{"key":"e_1_2_1_3_1","first-page":"4","volume-title":"Proc 2nd Int Syamp Protein Metabolism and Nutrition, Flevhof, The Netherlands","author":"Blaxter K L","year":"1977"},{"key":"e_1_2_1_4_1","first-page":"13","volume-title":"Proc Ammonia and Acidification Eurasap Symposium","author":"Buijsman E","year":"1987"},{"key":"e_1_2_1_5_1","first-page":"92","volume-title":"Volatile Emissions from Livestock Farming and Sewage Operations","author":"Christensen B T","year":"1987"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.3891\/acta.chem.scand.32a-0015"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/jsfa.2740290104"},{"key":"e_1_2_1_8_1","volume-title":"NPO\u2010redeg\u00f8relsen","year":"1984"},{"key":"e_1_2_1_9_1","unstructured":"Egn\u00e9rH1932Losses of nitrogen from manure by evaporation of ammonia.
