PROJECT DESCRIPTION

Agriculture contributes largely to atmospheric ammonia emissions. In Germany over 90 % of the ammonia emissions are produced by agriculture. To reduce these emissions especially from livestock faming, there are different options. The SAFT project deals with reduction of emissions during slurry storage in barns by acidification.

By acidifying the slurry with a strong acid (e. g. sulfuric acid), the pH can be decreased below 5.5 so that NH4+/NH3-balance is shifted and there is no more NH3 formation in gaseous form. As a result, the manure value of the nitrogen in the slurry remains loss-free up to the field. By the pH shift, the typical microorganisms, which occur in particular in deeper anaerobic layers in the slurry, are inactivated. Due to the microbial inhibition also a reduced methane formation is expected.

Aim of this project is to ensure safe and user-friendly logistics and handling of acid for application to the slurry, which is stored under the animals within the barn. Together with project partners a technology for distribution of the acid in the slurry should be developed. Application will be controlled by process computer. Additionally the process computer is needed for data acquisition and processing.
