Sierrablen Mini

The Sierrablen Mini range utilises a combination of both controlled release and conventional fertiliser technologies with 4 - 5 month longevity.

Different nutrient inputs or release characteristics can be achieved depending on your requirements including quick response or slower, steadier release patterns based on the analysis selected.

The mineral polyhalite is a component part of the Sierrablen Mini range. Polyhalite is a naturally occurring mineral fertiliser containing potassium, magnesium and calcium. We have found that the addition of polyhalite into our fertilisers results in improved turf colour, turf quality, turf vigour and growth rates.

Sierrablen Mini fertilisers contain over 60%+ controlled release N in the form of our Poly-S technology.

The Poly-S in Sierrablen Mini is a controlled-release nitrogen source that delivers nitrogen gradually and consistently over a 4 – 5 month period. The nutrient release is primed by moisture permeating through the outer polymer channels, through micro-channels in the sulphur layer and into the nutrient core where the urea is solubilised.

Once the urea is solubilised it is released and made available for plant uptake. This means that the fertiliser is released at an optimum rate for plant uptake and the risk of leaching losses is minimised.
