Granular Controlled Release Fertilisers

Controlled Release – Polymer Coated

GBR offer controlled release granular fertilisers that are polymer coated to give longevity of 3-4 months or 5-6 months depending upon the coating thickness. Coated granules provide consistent feeding for better turf quality. The coatings are not affected by drastic temperature changes or excessive rainfall and are suitable for turf which has varying pH balances. The percentage of coated granules is balanced to give suitable release patterns.
