ICL Sierrablen 27-5-5 (8-9 Months) Fertiliser

On application to turf, the Everris Sierrablen granule takes up moisture 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 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.
