Controlled release fertilizers are based on polymer-coated fertilizer granules. Fertilizer granules consist of soluble nutrients, are encapsulated in a polymeric shell coating. Following application, soil moisture slowly penetrates through the coating which begins a gradual dissolution of the nutrients inside the granule. The dissolved nutrients diffuse through the coating to the root zone, providing the plant with available nutrients at measured portions according to its growth needs.
