Control release fertilizers (CRF's) are coated fertilizers that release nutrients over an extended period of time at a rate driven primarily by temperature and moisture of the ischolar_main zone. Polymer coated fertilizers (PCF's) were also a type of CRF's, which are solid or other nutrient core, coated with various polymers ("plastics"). Fertilizer use efficiency can be increased by application of polymer coated fertilizer compared to common fertilizers due to very less nutrient losses. Most common three marketed products are Nutricote, Osmocote and Polyon. Coatings are tough, resist to damage and thin. Nutrient release is due to controlled diffusion, which is fairly constant over time. Release depends on coat thickness, chemistry, temperature and moisture.

Polymer coated fertilizers (PCF's) were also a type of CRF's, which are solid or other nutrient core, coated with various polymers ("plastics"). Fertilizer use efficiency can be increased by application of polymer coated fertilizer compared to common fertilizers due to very less nutrient losses. Most common three marketed products are Nutricote, Osmocote and Polyon. Coatings are tough, resist to damage and thin. Nutrient release is due to controlled diffusion, which is fairly constant over time. Release depends on coat thickness, chemistry, temperature and moisture.
