Crystal Green Pearl® Fertilizer
Enhanced efficiency fertilizer developed using nutrient recovery that puts your crops in control of nutrient uptake with reduced runoff and soil fixation.


About Crystal Green Pearl® Fertilizer
Crystal Green Pearl fertilizer uses Crop-Driven Release™ technology to provide phosphorus, along with nitrogen and magnesium (5-28-0 with 10% Mg), when roots need it, benefitting crops with better phosphate control and uptake for higher yields all season long. Crystal Green Pearl is available in SGN 90 and SGN 150.
Key Nutrients

DERIVATION
MgNH₄PO₄ - 6H₂O
MAGNESIUM AMMONIUM PHOSPHATE HEXAHYDRATE

MADE FROM RECOVERED NUTRIENTS
The Most Sustainable Fertilizer
Crystal Green Pearl is produced using Ostara’s nutrient recovery technology that reclaims and reuses excess phosphorous and nitrogen from municipal and industrial water supplies. By removing excess phosphorous from wastewater and turning it into high-efficiency fertilizer to reduce nutrient loss to global waterways, Crystal Green Pearl closes the phosphate loop.
HOW CRYSTAL GREEN PEARL WORKS
Gets to the Root of Nutrient Uptake
Crystal Green Pearl fertilizer releases phosphate, plus nitrogen and magnesium, in response to organic acids emitted by roots. With ongoing access to phosphate according to crop demand, Crystal Green safely supplies the roots with nutrients needed for optimal plant growth.
BENEFITS
Produce More, Waste Less
Using Crop Driven Release Technology™, Crystal Green Pearl fertilizer optimizes uptake and reduces soil tie-up and nutrient runoff for maximum efficiency. By preventing runoff, Crystal Green Pearl helps protect local water resources while increasing yield. Farmers finally have optimized nutrition for crops that increases profitability and production while positively impacting the environment at the same time.
SOIL TYPES
