BioCover  is specialized in sustainable use of organic fertilizers (slurry) and has developed the SyreN system for application of slurry to farmland.

SyreN system uses acidification (sulphuric acid) to change ammonia (gas) to ammonium (salt) during application of slurry. This reduces the emission of ammonia with up to 70%.  At the same time the method applies the correct amount of plant available Sulphur.  The increased efficiency of the nutrients optimizes slurry logistics, economy and eliminate negative environmental effects from slurry application – PM 2.5 air pollution and eutrophication.
