Slow-Release Fertilizer

Slow-release fertilizer, also called “slowly available,” are a part of many turfgrass fertilization programs. They provide greater longevities of available N than quick-release sources, and are safer to use on turfgrass because of their lower burn potential. This group includes both coated and uncoated sources.

Dependable & Steady Extended Nitrogen Release

XCU® Slow-Release Fertilizer pprovides gradual, steady nutritional uptake for up to 10 weeks of plant response. XCU® fertilizer has a high nitrogen (N) content (43%) with the addition of sulfur (4%), which provides added nutrition to the plant and can amend the soil. The value is more area can be covered per application using less fertilizer, which is more efficient and economical. Also, with less N lock-off more of the applied N is taken up and utilized by turfgrass or plants in the expected time frame.

Quick Green-Up with a Steady Supply of Nitrogen.

NITAMIN® targeted foliar nitrogen (N) is a patented, liquid nutrient source. It is designed to make some of the N immediately available for quick green-up, while reserving the rest for a steady supply of N to the turfgrass. NITAMIN® foliar fertilizer has a high N content—yet a lower salt index than a straight urea solution—which adds a critical margin of performance, efficiency and safety.


MU: Methylene Urea
