Whole system effect of acidification in house Acid treated slurry Untreated slurry Gaseous emission Gaseous emission 100 kg N in pig manure 9 kg N 32 kg N NH3emission Animal houses Manure stores Applied in field NH3emission Animal houses Manure stores Applied in field 91 kg N 68 kg N N in slurry N in slurry

  2. Conclusion Separation may be a relatively low cost technology contributing to harmony In house separation is an efficient NH3 reduction technology Ammonia emission in the field is reduced by • Injection: Efficiency related to slot volume • Trail hose application: Efficiency related to crop height • Incorporation of manure applied in the field
