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.


  • 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.


  • Apply the fertilizer with a spreader just after scarifying to allow the granules to disperse into the sward.
  • Apply the fertilizer evenly after preparation of the soil and just before sodding. The roots of the sod should touch the granules.
  • Seeding – Apply the fertilizer with a spreader and work the fertilizer into the top 3 cm of the soil before seeding.
  • Over-Seeding - Open up the soil and apply the fertilizer with a spreader, reseed afterwards.
  • Apply the fertilizer after mowing with a spreader
