SCU^® Sulfur-Coated Urea is a controlled-release nitrogen fertilizer with a guaranteed analysis of 37% nitrogen and 17% sulfur. SCU can be purchased in two sizes - SGN 245 and 210. On request, you can also purchase 31% nitrogen with 26% sulfur and an SGN 150.

Fast and Long-Lasting

A complete, balanced turfgrass fertilization program has two parts. Quick-release nitrogen (such as urea) is used for fast green-up and immediate feeding. A slow-release formula provides longer-lasting nourishment.

Coating urea with sulfur, an essential turf nutrient in its own right, makes time release possible. Typically, sulfur-coated urea lasts from eight to 12 weeks, depending on environmental conditions. A sustained, slow release of sulfur and nitrogen helps the uptake of other nutrients essential for turf growth, color and disease resistance. The slow-release process also reduces the number of applications and prevents turf burn due to overapplication or overlapped coverage.

Built-in Quality

SCU sulfur-coated urea is 37% nitrogen. We could increase the nitrogen content and save freight costs, as some companies do, but that would compromise quality. To boost nitrogen, other producers of sulfur-coated urea add a harder, more brittle coating. This process can reduce the coating's thickness, which unfortunately overlooks a very important consideration. Sulfur-coated urea takes some pretty rough handling - in loading, shipping, blending and bagging - before it hits the ground and reaches your turf. The result? Granule coatings can break down and release all the nitrogen at one time.

Our solution is a tougher, more pliable "second skin." SCU sulfur-coated urea from Nu-Gro Technologies is produced in a continuous process that sprays preheated urea granules with molten sulfur. This yields highly uniform urea granules and pays off in better sizing and finished blends. After the sulfur coating is applied, we add a proprietary sealant to provide the durability needed for consistent performance on turf.

Proven Performance

Tests prove the superiority of our SCU. The fertilizer industry uses a standard seven-day test to measure nitrogen plant food release rates. A 50-gram product sample is placed in 250 milliliters of water at 100 degrees F for seven days. A measurement determines the percentage of nitrogen released from the sample during the test period.

The industry uses a second test to simulate the effects of shipping, blending and other handling. Coated nitrogen is dropped 35 feet down a pipe onto a steel plate. The material is collected, and the seven-day dissolution test is run again. These tests have shown that SCU sulfur-coated urea tops other leading products by releasing less of its nitrogen after simulated handling.

The Preferred Sulfur-Coated Urea

In head-to-head test-plot comparisons of turf color, SCU sulfur-coated urea outperforms other products. Turf fertilized by SCU sulfur-coated urea turns a rich, healthy green soon after application and keeps its color throughout the test period. Better fertilization comes from less denitrification, volatilization and leaching. In overall quality, turf color, density and uniformity, no brand beats our SCU sulfur-coated urea.
