XCU® Polymer-Coated Sulfur-Coated Urea Technology

Extended Nitrogen Nutrition for More Efficient Turf Programs

XCU® is a dual-coated urea technology, supplied by Nu-Tec, designed to provide gradual nitrogen release and up to 10 weeks of plant response.

Improving Consistency in Coated Urea Release

Traditional sulfur-coated urea can release nitrogen abruptly when the coating cracks. XCU® combines sulfur and polymer coatings to help create a more controlled, consistent nitrogen release profile.

A Dual-Coated Source of Slow-Release Nitrogen

XCU® combines a polymer-protected urea core with sulfur and polymer coatings to support coating durability and gradual nutrient release. It is available in Mini and Regular granule sizes with different nutrient analyses, sulfur levels and SGN ranges to support different finished fertilizer blends and application requirements.

How Polymer and Sulfur Coatings Regulate Nitrogen Release

  1. Moisture Penetrates the Coatings

    Soil moisture moves through the sulfur and polymer layers toward the urea core.

  2. Nitrogen Dissolves Inside

    Moisture dissolves the urea, increasing pressure within the granule.

  3. The Polymer Layer Moderates Release

    The polymer coating helps regulate the movement of dissolved nitrogen from the granule, supporting a more gradual and consistent nutrient supply.

  4. Sulfur Returns to the Soil

    After nitrogen is released, the sulfur coating eventually breaks down in the soil.

Longer-Lasting Nutrition with Greater Application Efficiency

XCU® is designed to extend plant response while helping professional turf programs make more efficient use of each application.

Up to 10 Weeks of Response

XCU® provides gradual nitrogen delivery designed to support up to 10 weeks of plant response.

Consistent Nitrogen Release

The coating system helps moderate sudden release and maintain a steadier nutrient supply.

Efficient Use in Blends

XCU® can be incorporated at different rates within finished fertilizer blends to help balance controlled-release nitrogen performance with overall blend requirements.

Flexible Granule Sizing

XCU® Mini is a 41-0-0 grade with 7% sulfur and an SGN range of 120–180, while XCU® Regular is a 43-0-0 grade with 4% sulfur and an SGN range of 220–270, providing options for different finished blends and application requirements.

Where XCU® Technology Fits

XCU® technology is suited to golf, sports turf and professional lawn care programs where gradual nitrogen release and extended plant response are required, including applications managed by superintendents, municipal turf teams and professional landscapers.
