Summary

Animal manure is the major source of atmospheric ammonia (NH3) and the most important source of malodorous gases in the countryside. Emissions of these gases from the manure are described by a two-film model, which includes diffusion and convective mass transport of the gases from liquid manure to the atmosphere. For NH3 as well as many odorous compounds, pH is very important for the emissions because they are either bases or acids, which means that a large fraction of the compounds are charged at typical manure pH. Therefore, the influence of acid-base chemistry of gaseous release is shown for the base NH3 and the acid hydrogen sulfide. Examples of algorithm's for assessing NH3 emission are given.
