ICL have added Ostara's Pearl® Technology to their premium controlled-release Sierrablen Plus fertilizers and it is providing significantly increased rooting and more efficient nutrient use over traditional ammonium-phosphate sources. With Pearl Technology they have eliminated the risk of phosphorus leaching into the environment or it irreversibly locking onto soil particles: Pearl only releases in response to organic acids produced by the roots and therefore will be taken up as per the plants' requirement.
The key benefits of Root Activated™ continuous release phosphorus, including increased turf rooting density and better phosphorus use efficiency, have been proven through published independent research trials in the UK and US.
