Crystal Green is the first sustainable struvite-based granular fertilizer (5-28-0-10Mg) to provide critical nutrients all season for a variety of crops and soil types. When placed near the seed or roots, Crystal Green provides a slow-release of phosphorus, nitrogen and magnesium in one powerful, plant-available granule.

Composed of magnesium ammonium phosphate hexahydrate (struvite), Crystal Green performs differently and better than any other phosphate fertilizer. Rather than being water soluble, and susceptible to tie-up and leaching, Crystal Green’s solubility is activated by citrate acids from growing roots. Responding to plant demand means improved nutrient efficiency, reduced nutrient loss from tie-up and leaching, and the potential for greater yield and quality.
