Sierrablen

The Sierrablen range features Scotts unique resin and/or Poly-S coated fertilizer granules which rely on soil temperature as their main mechanism of release.

On application to turf, the granule takes up mositure from it environment gradually dissolving the enclosed nutrients.  At soil temperatures just above 0 degrees centigrade, pressure starts to build up within the granule forcing the nutrients through the semi-permeable resign coating.  The length of release is determined by the thickness of the coating surrounding the granule.  The thicker the coating, the slower the daily release rate and so the longer the product lasts.  Therefore nutrient is accurately released, matched exactly to turf growth requirements.  The combination of resin and Poly-S technology in the same analyses results in improved Nitrogen release characteristics and better low temperature performance.  To enable a quick response in the Spring, most products contain some lightly coated material.

Working Principle of a Resin Coated Granule

Granules contain NPK, B, Cu, Fe, Mn, Mo and Zn (Mg is added for specific products

Water penetrates through the coating and dissolves the nutrients inside the granule

Influenced by the temperature, the nutrients are released at a constant, regular and controlled rate during the longevity

Turfmix 27+5+5+Fe
Contains controlled release NPK and a low amount of fast start Nitrogen for a more gentle response.

Turfmix 28+5+5+Fe
Contains controlled release NPK and a fast start portion of Nitrogen for an immediate response even at low soil temperatures.

Turfmix 15+0+22+Fe
Contains controlled release NK and a fast start of Nitrogen, Potassium and Iron for an immediate response.

24+5+10+Fe
For maintenance fertilization on all sports turf areas.

14+5+21+Mg+Fe
A high quality NPK Spring and Summer fertilizer, particularly good where a higher K to N ratio is required.

Mini 0+0+27
For fine turf during renovation, and Winter season pitches grown on high percentage sand root zones.
