Ekompany A controlled release fertlizer is a granulated fertilizer that releases nutrients gradually into the soil within a given period, measured in months, in a controlled way. The formulations are often NPK's with - if desired - secondary nutrients like calcium and magnesium. Also trace elements can be added.

The difference between slow-release fertilizer and controlled-release fertilizer. Slow-release fertilizer is a new type of fertilizer that can slow down or control the rate of nutrient release, as opposed to fast-acting fertilizer.Broadly speaking, slow-release fertilizer includes two types of slow-release fertilizer and controlled-release fertilizer.Controlled-Release Nitrogen Fertilizers Pioneer Seeds In North America, nitrogen fertilizer is largely applied as anhydrous ammonia, UAN solutions or urea. However, these forms of nitrogen can be lost if adverse (primarily wet) weather conditions precede their uptake by crops. Controlled-release nitrogen fertilizers can reduce these losses by delaying the initial release of N and providing it gradually to better match its availability with cropControlled fertilizer release via tunable poly(vinyl Jun 14, 2018 Fertilizers that are coated/encapsulated in powder or granule form are called controlled release fertilizers (CRF).3,4,5,6,7,8,9. In order to generate controlled release fertilizers, various organic polymeric materials can also be used in addition to inorganic materials such as sulfur.Enhanced-Efficiency Fertilizers - University of Florida Controlled-release urea (polymer/sulfur coated) 500 to 1,000.
