Versatility of the MAnure PHosphorus EXtraction (MAPHEX) System in Removing Phosphorus, Odor, Microbes, and Alkalinity from Dairy Manures

Animal manures contain nutrients [primarily nitrogen (N) and phosphorus (P)] and organic material that are beneficial to crops. Unfortunately, for economic and logistics reasons, dairy manure tends to be applied to soils near where it is generated. Over time P concentrations in soils where dairy manure is applied builds up, and is often in excess of crop demands.
