Learning about slurry acidification from the Danes

Using acidifiers in slurry reduces ammonia and emissions but costs, regulations, impact on soil and uncertainties around safety are a concern, writes Stephen Cadogan

In Ireland, Low Emission Slurry Spreading (LESS) is the main method to reduce ammonia emissions.

Teagasc researchers have revealed "very good" reduction of ammonia and greenhouse gas emissions from using acidifiers in slurry.

All EU countries are trying to reduce ammonia emissions, to reach 2020 and 2030 targets set by the Clean Air agreement.
