Sierrablen	Sierrablen Mini

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 its 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 that 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
