Unlike conventional phosphate fertilizers, which release nutrients upon watering or irrigation, Crystal Green® releases nutrients in direct response to root demand- when the plant releases organic acids, Crystal Green® releases nutrients. This results in a steady source of phosphorus (along with nitrogen and magnesium) throughout the growing season.
Crystal Green® is sustainably produced by Ostara using nutrient recovery technology that combines phosphorus, nitrogen, and magnesium into pure crystalline granules. By adding Magnesium to nutrient rich water sources in a pH controlled environment, nutrients crystalize to form struvite (5-28-0-10Mg), like scale in a kettle.
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.
|Total Nitrogen (N)||5%|
|Available Phosphate (P2O5)||28%|
Studies show an average recommended rate of 25% of the total phosphorus as Crystal Green, with rate variances depending on crop and soil type. Example: If a grower used 40 pounds of actual P on Canola, 10 pounds of the 40 should come from Crystal Green®.
