Ammoniakemissie uit varkensstallen met uitloop

Abstract

Within this project the ammonia emission from houses for growing-finishing pigs with a paved outside yard was determined on two organic farms and in the Star+ house at VIC Sterksel. The ammonia emission was estimated by using a computer model that calculates these emissions with measured local parameters, i.e. fouled area of floor and manure pit, temperature, ammonium content and pH of the emitting surface, and the air velocity above the emitting surface. Within Star+ also measurements at housing level were done. From this study it is concluded that the ammonia emission level from houses with a paved outside yard can be similar to houses without outside yard. This can be realized by a good pen design that enables a reduced area of the manure pit and reduced floor fouling. Furthermore, it is concluded that the determination of ammonia emission by model calculation based on local measured input parameters has good prospects. Further validation of this method, however, is advised.
