Controlled Release Fertilisers

Sinclair Sincrocell controlled release fertilisers are granular compound fertilisers coated with a semi-permeable membrane through which water-soluble nutrients can pass at a controlled rate.  The nutrients are released in response to temperature to syncronise nutrient output with plant demand and are independent of pH, moisture and growing media composition.  Sincrocell contains all essential plant nutrients except calcium, which is provided in the liming material, and a full range of trace elements.  The tough polymer coating gives superior resilience to mechanical handling and temperature extremes.  Sincrocell is available in 4 variants with longevity from 5-6 months up to 15-16 months.
