Abstract
Ammonia emissions contribute substantially to environmental pollution and cause severe acidification. In Sweden, 20-25% of the total ammonia emission derives from manure in animal buildings. One technique to decrease ammonia emissions from animal buildings is to apply emission-reducing additives in the manure. However, the efficiencies of many of the manure additives on the market have not been determined, and those additives that have been evaluated are difficult to compare due to different test methods and methods of evaluation. The objectives of this study were to investigate the abilities of different manure additives in reducing ammonia emission, for how long they would be efficient, and to which cost the additives can be used. The results show that high reductions (up to 50%) in ammonia emissions are possible to obtain with some of the additives, at least during the first week after the application of the additives. The reductions decrease over time, and they are hardly noticeable after six weeks. The costs to which these additives can be used are high in relation to the amount of nitrogen they save. 33 refs, 3 figs, 13 tabs
