NUTRION CRF (controlled release fertilizers) is an effective way to make the availability of nutrients coincide with plant requirements by controlling their release into the soil solution. When the controlled release fertilizers granules are applied to the soil, the coating acts as a semi-permeable barrier that allows continuous release of nutrients to the root zone.
Our CRF product range, are based on polymer-coated fertilizer granules. During the production process, water-soluble nutrients are encapsulated in a polymeric case. This case prevents the immediate dissolution of the fertilizer when applied to the soil. The thickness of the case determines the longevity of nutrients release.
