Project: MLMMI 2011-01
To facilitate the choice of a suitable solid-liquid separation technology for Manitoba by providing additional information on how environmentally and agronomically available P and metals are separated with different separation methods and to provide information on P and metals in solid and liquid separates which would be useful in deciding the best use of the end product of solid-liquid separation.

The primary aim of liquid-solid separation of livestock manure in Manitoba is to obtain an N-rich liquid separate which can be used mainly as a nitrogen fertilizer close to the source of manure and a solid separate rich in phosphorus to replenish soils elsewhere with phosphorus and/or to use as a soil amendment. The separation methods used in this study achieved the above objective. The separated liquids and separated solids differed in both concentration and form of phosphorus and metals from that in raw manure. General practices and strategies, used for management of raw (whole) manures, are directly applicable for management of manure separates in crop production.
