Full Description

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.

Our Recommendation

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