Ammonia is a powerful air pollutant and a highly reactive form of nitrogen. Northern Ireland has very high and increasing ammonia emissions.  Agriculture is responsible for 94% of atmospheric ammonia in Northern Ireland with 69% from cattle.

High levels of ammonia:

  • Causes damage to plants and sensitive habitats, including designated sites, and species loss; and
  • Contributes to the formation of Particulate Matter which adversely affects human health

Nitrogen loss by ammonia – reduces the fertiliser value of slurry and manure – requiring increased chemical fertiliser purchases. The UK is obliged under international law to reduce ammonia emissions by 8% by 2020 and by 16% by 2030 (from 2005 levels). DAERA is working with Stakeholders to develop an Action Plan to reduce ammonia emissions.
