AMMONIA EMISSION REDUCTION MEASURES IN DAIRY CATTLE FARMING

The article discusses the possibilities of ammonia emission reduction in dairy cattle farming. In earlier research by the authors of the article it has been found that updating of the production technology and production of liquid manure increase ammonia emissions approximately 1.8 times. Therefore, it may hinder implementation of the national aims determined in the country on a gradual reduction of ammonia emissions. Therefore, the ammonia emission reduction measures recommended in special literature are summarised as well as their evaluation by application of the expert method is presented. The measures approved by the experts are divided into three groups depending on the capital investments that are needed for their implementation. In the research it has been stated that for further reduction of ammonia emissions in dairy farming it is sufficient to improve the animal welfare measures and enlarge usage of liquid manure chemical or biological additives, but it is not necessary to invest large capital investments for the building of new dairy cattle housing facilities and farm manure storages.
