In 1961, the United States developed sulfur-coated urea (SCU). In the same year, Japan developed a coated high-efficiency fertilizer (C.S.R, Coated Slow-release). China began to study and apply slow-release nitrogenControlled-Release Fertilizers ICL Specialty Fertilizers They release N by slowly dissolving, decomposing or, in the case of sulfur-coated urea, seeping through cracks in the coating. Growers have less experience with newer CRF sources that use resin, polymer, or plastic coatings because along with higher technology comes higher cost.Enhanced Efficiency Nitrogen Fertilizers for Turfgrasses Aug 16, 2016 Slow-release nitrogen fertilizers can be grouped into different categories, including the coated ureas, methylene ureas, and natural organics (Table 1 below). Coated ureas. Coated ureas include sulfur-coated urea (SCU) and polymer-coated urea (PCU).
