Description

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.

Advantages

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.

  • Controlled-release Poly-S nitrogen for strong turf response and 3+ month longevity.
  • Root-activated™, continuous-release phosphorus, nitrogen and magnesium resulting in increased rooting.
  • Contains Polyhalite with K, CaO and MgO.
  • Circular nutrients N, P and MgO recovered from phosphorus-rich water streams.
  • Earlier harvest time when used for turf production.
