Description

We have added Ostara's 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.

  • Root-activated™, continuous-release phosphorus, nitrogen and magnesium resulting in increased rooting.
  • Circular nutrients N, P and MgO recovered from phosphorus-rich water streams.
  • Earlier harvest time when used for turf production.
Directions for use
Renovation
Apply the fertilizer with a spreader just after scarifying to allow the granules to disperse into the sward
 
Sodding
Apply the fertilizer evenly after preparation of the soil and just before sodding. The roots of the sod should touch the granules
 
Seeding and over-seeding
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

Sierrablen Plus Turf Starter includes Pearl® Technology, a unique Root Activated™ continuous-release phosphorus recovered from phosphorus-rich water streams. This high phosphorus analysis with proven performance for sod growers, is designed for laying sod and for adding to renovations where maximum rooting is the aim. It is preferable to use this product alongside applications of additional nitrogen to encourage turf growth.
