Abstract
The emission of ammonia from manure accounts for a major part of the nitrogen emission in agriculture. The annual ammonia emission from livestock manure is estimated at 30,000 tons of nitrogen. Nitrogen emissions from fur animal farms are estimated to be about 4000 tons a year. Nitrogen evaporation from artificial fertilizers in the field is estimated to be about 7500 tons a year. Industrial ammonia emissions are much less, amounting to about 1000 tons of nitrogen a year. The annual emission of ammonia nitrogen from all domestic sources is estimated to be 43,000 tons. Of this amount, manure is the source of roughly 80%. Nitrogen emissions arising from ammonia vary regionally from 0.01 to 0.4 g m-2. Ammonia emissions throughout Europe contribute to the deposition in Finland. The total deposition is about 45,000 tons of nitrogen. If the ammonia deposition were distributed evenly over the whole area of Finland, the nitrogen would amount to 0.13 gm-2.
