Much of the triazone research has focused on its use as a foliar fertilizer (Clapp, 1993; Widders, 1991). The third major category of slow-release N fertilizers is those that are slow-release because of a physical coating around the urea fertilizer prill. Typical coating materials are sulfur, wax, or a plastic resin, or someControlled- and Slow-Release Fertilizers - Chemical Controlledrelease fertilizers are generally coated products. Slow-release fertilizers are noncoated products in which the nutrient release is uncontrolled but slow; these are mainly urea-aldehyde reaction products but also include other slowly soluble products such as fertilizer spikes and ion exchange resin fertilizers.
