Pearl® Technology blends a unique, recycled, slow-release phosphorus into premium controlled-release fertilizers. Providing significantly increased rooting and more efficient nutrient use over traditional phosphorus sources.
The Core of Pearl Technology
At the heart of Pearl Technology is the unique process of recycling phosphorus from renewable sources—specifically from wastewater. By leveraging Ostara’s Crystal Green process, the technology captures and recycles valuable nutrients that would otherwise contribute to environmental pollution. This phosphorus is then transformed into a high-value, slow-release fertiliser that integrates seamlessly into the soil, providing nutrients directly to the roots of turf in a controlled manner. This method not only ensures efficient nutrient use but also significantly reduces the potential for runoff and the associated environmental damage.
The Pearl® process
Sierrablen Plus with Pearl® Technology incorporates Ostara’s Crystal Green. Crystal Green is sustainably produced and is the first continuous-release fertiliser to provide Root-Activated™ phosphorus. Crystal Green is recovered from wastewater utilising a unique process which allows recovery of a pure struvite granule 5-28-0-16MgO. Crystal Green’s unique mode-of-action releases phosphorus, nitrogen and magnesium, only in response to organic acids produced by growing roots. As the roots produce organic acids the granules release phosphorus, fertilising the plant on demand, all-season long.
As plant demand increases, phosphorus demand increases. This reduces the environmental impact caused by excessive leaching and run-off of nutrients.
Environmental impact and sustainability
Pearl Technology is also a key player in promoting sustainability within the turf management industry. By recycling phosphorus from wastewater, the technology helps close the nutrient cycle, which is pivotal in reducing phosphorus losses to water bodies and preserving finite natural resources such as rock phosphate. This approach not only supports the principles of the circular economy but also aligns with global efforts to reduce environmental pollution and promote resource efficiency.
