Crystal Green

Crystal Green is sustainably produced by Ostara using nutrient recovery technology that combines phosphorus, nitrogen, and magnesium into pure crystalline granules. Crystal Green is virtually water insoluble and releases only in response to organic acids produced by growing roots. As the roots produce citrates, Crystal Green responds with a healthy release of phosphorus, fertilizing plants on demand. As plant demand decreases, nutrient release from Crystal Green is reduced consequently providing a more consistent feeding of nutrients compared to conventional phosphorus fertilizers. Crystal Green’s unique mode-of-action increases fertilizer efficiency and minimizes nutrient loss.

Crystal Green is distributed in the United States, Canada, and Europe through a network of retailers, blenders, and distributors to professionals in the agriculture, turf, and horticulture markets.
