struvite

Struvite is a phosphate fertilizer that contains a significant amount of nitrogen and magnesium, and it is an effective alternative source of rock phosphate to maintain the agricultural production system. Struvite precipitation occurs in an equimolecular concentration of Mg2+, and  at slightly alkaline conditions. Addition of a source of Mg is essential to maintain the favorable condition of PO4 and Mg.

The slower nutrient leaching loss and its fertilizer quality make struvite an eco-friendly fertilizer.
