Forced precipitation of struvite (magnesium ammonium phosphate hexahydrate, MgNH4PO46H2O) in wastewater treatment has recently received increased attention as a method of phosphorus (P) recycling. While both struvite and phosphate rock (PR) can be used as a P fertilizer on acid soils, PR is ineffective in calcareous soils. Magnesium (Mg) phosphates such as struvite, on the other hand, could be a more useful fertilizer in alkaline soils, especially in organic production where conventional P fertilizers are not an option.
