Emerald 10-0-20 provides balanced slow-release nitrogen and high potassium to support healthy growth, color, and durability through challenging seasons. Formulated with quality nutrient sources and micronutrients for steady, reliable feeding.

XCU slow-release fertilizer provides gradual, steady nutritional uptake for up to 10 weeks of plant response. XCU fertilizer has the highest nitrogen (N) content (43%) and lowest sulfur content (4%) of any polymer-coated sulfur-coated urea (PCSCU) on the market. 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.

Supports stress tolerance, strength, and overall turf health.

Provides controlled feeding to avoid growth surges.

Delivers key trace elements for balanced turf nutrition and dark green turf color.
