Anaerobically digested dairy manure has a high potential for struvite recovery.
Digested dairy manure is rich in ammonium, orthophosphate, and magnesium.
High ionic strength, Ca, and alkalinity hinder struvite formation in dairy manure.
Struvite recovery potential is defined by the least molar activity of struvite ions.
A mix of measures may overcome hindrances of digested manure to struvite formation.
