Struvite Mineral magnesium ammonium phosphate MAP

Struvite (MgNH4PO4.6H2O), sometimes also called Magnesium Ammonium Phosphate Hexahydrate (MAP). Struvite is a bioavailable, slow-release fertiliser; it is compact and can be stored, transported and applied easily, and does not smell. Struvite, which contains valuable nutrients like nitrogen and phosphorus, can be applied to soil and used as fertiliser for crops.

Struvite mineral commonly found as a product of organic decay in putrescent matter, canned foods or other bacterial action on organic compounds, and as a constituent of human kidney and bladder stones in alkaline and infected urines.

Struvite can be applied to fields just like any other fertiliser. In a simple granulation drum, the powder can be transformed into granules. In granular form, a fertiliser is easier to apply and does not cake in moist environments. Struvite performs comparably to diammonium phosphate (DAP) fertiliser and has the following advantages:
    Bio-available: The nutrients in struvite can be readily absorbed by the plant.
    Slow-release: Due to its low solubility, struvite guarantees a slow but steady nutrient supply.
    Highly pure: the struvite has little contaminants.
