This granular fertiliser combines Ostara Pearl® technology with ICL’s premium controlled-release Sierrablen Plus fertiliser. This combination provides significantly increased rooting and more efficient nutrient use over conventional ammonium-phosphate sources.
Sierrablen Plus Turf Starter includes Pearl® Technology, a unique Root-Activated™ continuous-release phosphorus recovered from phosphorus-rich wastewater. With Pearl Technology, ICL have eliminated the risk of phosphorus leaching into the environment or irreversibly locking onto soil particles: Pearl only releases nutrients in response to organic acids produced by the roots enabling them to be taken up as per the plants requirement. The high phosphorus analysis of Sierrablen Turf Starter has proven popular with turf growers and is ideal when laying new turf. Sierrablen Turf Starter can also aid turf renovations where maximum rooting is essential.
The key benefits of Root-Activated™ continuous-release phosphorus, including increased turf rooting density and better phosphorus use efficiency, have been demonstrated through published independent research trials in the UK and US.

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 laying the turf. The roots of the turf should touch the granules.
To seed, apply the fertiliser with a spreader and work the fertiliser into the top 3 cm of the soil before seeding. To over-seed, open up the soil and apply the fertiliser with a spreader and re-seed afterwards.
