FAQ's // My TurfCare - Login Services Products Education Our Company Contact Enhanced Efficiency Fertilizers Urea Coated Technology Controlled/Slow-Release Fertilizer Technology Controlled/Slow Release Fertilizer products are designed to provide a slow, even distribution of nitrogen with extra longevity. CRF/SRF technologies protect turf, improve fertilizer efficiency, reduce leaching and runoff, which results in an eco-responsible choice to ensure consistent plant health. Technology SCU™ >> Sulfur-Coated Urea Sulfur Coated Urea (SCU) is an economical slow-release fertilizer produced by coating a urea granular with Sulfur and wax. Sulfur is very effective at repelling water, however sulfur coatings can be brittle. To protect the sulfur from breaking down too quickly, a wax is applied over the sulfur layer to stabilize the nitrogen release curves. Once water finds its way inside, the granule expands and the coating factures allowing urea to flow out. SCU works on the premise that some granules will take longer to fracture and release their nutrients than others. Over the course of time, this “mix” of release times results in continuous nitrogen feeding. Technology DurationCR® >> Polymer Coated Urea (PCU) Polymer Coated Urea (PCU) consists of urea granules coated with a thin layer polymer, typically a polyurethane. Polymer coatings are extremely durable and resist damage during handling and transport, preserving their controlled-release properties. Through osmotic diffusion, water diffuses through the polymer layer and slowly dissolves the urea core. Over the course of many weeks or many months, urea slowly diffuses through the polymer layer providing an even, controlled distribution of nitrogen over a large portion of the growing season. Once the urea has been depleted, the thin polymer shell is degraded by soil microbes. PCU's are an environmentally responsible technology due to providing gradual nitrogen release, which reduces leaching and runoff. Technology XCU® >> Polymer Coated Sulfur Coated Urea (PCSCU) Polymer Coated Sulfur Coated Urea (PCSCU) is urea coated with sulfur and polymer. PCSCU also has an outer wax layer. PCSCU is essentially the “Cadillac” of coated SRN fertilizers; it is the most expensive to manufacture but provides the longest and most steady nitrogen release properties. Technology NUTRALENE® >> NITROFORM® >> Reacted Slow Release Nitrogen Reacted Slow Release Nitrogen consists of urea granules which are not coated with any polymers, sulfur, or waxes. Instead, formaldehyde is reacted with urea granules to produce both methylene urea and urea-formaldehyde molecules. These new molecules form chains of varying lengths which help prevent against volatilization and leaching. This technology works harmoniously with natural soil microbes. Over time, microbes slowly break apart these chains, resulting in continuous nitrogen availability for up to 26 weeks. Reacted slow release nitrogen is influenced by soil temperature and moisture content. Stabilized Nitrogen Technology Stabilized Nitrogen is designed to inhibit the conversion of urea into nitrogen products which are no longer readily available for plant use. Stabilized nitrogen products reduce volatilization, nitrification/denitrification rates and leaching potential. In essence, stabilized nitrogen disrupts the nitrogen cycle. It helps urea absorb efficiently into the soil and keeps it readily available for plant use over longer time frames. Stabilized Nitrogen can be divided into two categories: “urease inhibitors” and “nitrification inhibitors. Technology ALL-N™>> UFLEXX®>> UMAXX®>> Urease Inhibitors Urease inhibitors are designed to inhibit the activity of “urease,” a key enzyme in the metabolic pathway of soil bacteria. When urea granules are deposited on the soil surface, they must be dissolved by water to be absorbed into the soil. If bacteria on the soil surface reach urea before it absorbs into the soil, the bacteria convert urea into anomia gas which immediately volatizes into the atmosphere. Urease inhibitors (such as NBPT) prevent this process from taking place.
