Are ammonia emissions from field-applied slurry substantially over-estimated in European emission inventories?

Ammonia, methane, and nitrous oxide emission from pig slurry applied to a pasture in New Zealand.

Much animal manure is being applied to small land areas close to animal confinements, resulting in environmental degradation. This paper reports a study on the emissions of ammonia (NH3), methane (CH4), and nitrous oxide (N2O) from a pasture during a 90-d period after pig slurry application (60 m3 ha-1) to the soil surface. The pig slurry contained 6.1 kg total N m-3, 4.2 kg of total ammoniacal...

Ammonia emissions from pig and cattle slurry in the field and utilization of slurry nitrogen in crop production Doctoral Dissertation

Volatilization of ammonia (NH3) from animal manure is a major pathway for nitrogen (N) losses that cause eutrophication, acidification, and other environmental hazards. In this study, the effect of alternative techniques of manure treatment (aeration, separation, addition of peat) and application (broadcast spreading, band spreading, injection, incorporation by harrowing) on NH3 emissions in th...

Evaluation and improvement of ammonia emissions inventories

Two case studies are performed to improve ammonia emissions inputs used to model fine particulate matter (PM2.5 is the portion of particulate matter smaller than 2.5 mm aerodynamic diameter) formation of ammonium sulfate and ammonium nitrate. Ammonia emissions are analyzed in detail for North Carolina and the San Joaquin Valley (SJV) of California, with a focus on the Charlotte, NC, and Fresno,...

Slurry Application Techniques to reduce Ammonia Emissions: Results of some UK Field-scale Experiments

Shallow injection, trailing shoe and band spreading machines were evaluated, in terms of their potential for reducing ammonia (NH3) emission, by making measurements after application and in direct comparison with surface broadcast applied cattle slurry (pig slurry on one occasion). Several sets of comparative measurements were made with each type of machine on both grassland and arable land (mo...
