About the project

Reducing nitrogen loss from livestock production by promoting the use of slurry acidification techniques in the Baltic Sea Region

Baltic Slurry Acidification aims to promote the implementation of slurry acidification techniques throughout the Baltic Sea Region. Slurry acidification techniques (SATs) will reduce the ammonia losses from livestock manure and thus reduce airborne eutrophication of the Baltic Sea. The usage of SATs will provide clear environmental benefit for the region. The use of SATs benefits also farmers by increasing the nitrogen use efficiency of their manure fertilizers and thereby decreasing their dependency on mineral nitrogen.

Background

Livestock manure is the main source of ammonia-nitrogen emissions in the Baltic Sea Region, which through atmospheric deposition results in a significant amount of nitrogen entering to the Baltic Sea. Ammonia emissions threaten also human health through the formation of particulate matter, which as a pollutant is estimated to have a high negative impact on human health.

Slurry acidification techniques can be used to reduce the ammonia losses from livestock manure in livestock housing, manure storages and from the fields during the application of manure. These techniques have been widely tested and implemented in Denmark. The three main types of SATs are:

  • In-house acidification of livestock slurry
  • In-storage acidification of stored livestock slurry
  • In-field acidification of livestock slurry during field spreading.

Activities

Core activities focus on establishing pilot SAT installations and field trials in countries around the Baltic Sea. Pilot installations and field trials will be used to disseminate knowledge to target groups via field walks and demonstrations to provide local experiences to help build end user confidence in these technologies.  The project will further clarify technological aspects and potential risks of acidification, analyse the environmental and economic implications, conduct market analysis and suggest policy recommendations that could help dissemination of SAT technology in the Baltic Sea region.

Timeframe

The project started March 1, 2016 and will end February 28, 2019.

Flagship status

Baltic Slurry Acidification is a flagship project of the Priority Area Bioeconomy under the EU Strategy for the Baltic Sea Region.
