Manure separation to better distribute organic matter
The primary purpose of manure separation is to produce a thick fraction with high organic matter and nutrient content and low moisture content. Slurry manure is fed through a manure separator that separates much of the thick material from the liquid portion. The thick material is a valuable fertiliser and can be transported over large distances. The thin fraction can be applied as fertiliser on the farm, on farmland in the proximity, or can be treated into a quality suitable for discharge in the environment or water drainage system.
Note: For this SLM technology case, the SPI report on Sustainable Land Management and Climate Change refers to: Gebrezgabher, S.A., et al. 2015. Factors influencing adoption of manure separation technology in the Netherlands, Journal of Environmental Management,150 (1).
