Sierrablen Plus Spring & Summer includes Pearl® Technology, a unique Root Activated™ continuous-release phosphorus recovered from phosphorus-rich water streams. This spring and summer fertilizer is designed to encourage healthy turf growth through the season providing great longevity from controlled release nitrogen.
We have added Pearl® Technology to our 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 we 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.
