Description of the measure

Separation of the slurry into a liquid and a solid part. This increases the nutrient effeciency in the liquid part

Comments on sustainability

The liquid part of the slurry can be spread on the grassland and does not leave a thick manure layer on the grass. The separated slurry has an easier infiltration into the soil. Less ammonia emissions are produced. Synthetic nitrogen fertilizer could be reduced through higher N content of slurry. For the separation, additional energy, working hours and investments are needed. Latter could be reduced by subcontractors.
