A controlled-release fertiliser (CRF) is a granulated fertiliser that releases nutrients gradually into the soil (i.e., with a controlled release period). The slowness of the release is determined by the low solubility of the chemical compounds in the soil moisture. Since conventional fertilisers are soluble in water, the nutrients can disperse quickly as the fertiliser dissolves.
Current Use of and Barriers to further Adoption of Controlled-Release Fertilizer. CRFs are not widely used in containerized greenhouse floriculture production except for stock plants, poinsettias, hanging baskets, and garden mums. Even in these few exceptions, CRFs are used as a supplement to water-soluble fertilizers.

The coating's thickness, along with temperature, determines how long the fertilizer lasts. For instance the 14-14-14 lasts four to five months at soil temperatures of 60°F, three to four months at 70°F, and one to two months at 80°F. Compared to other controlled-release fertilizers, Osmocote releases more nutrients in cooler soils. Polyon.
In the production of NPK compound fertilizer, the coating machine is usually used before packaging, and a film is added to the outer layer of NPK compound fertilizer.Coated fertilizer is a kind of slow-release and controlled-release fertilizer.
