PRODUCT OVERVIEW

XCU® slow-release fertiliser provides gradual, steady nutritional uptake for up to 10 weeks of plant response. XCU® fertiliser 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 fertiliser, which is more efficient and economical. Also, with less N lock-off more of the applied N is taken up and utilised by turfgrass or plants in the expected time frame.

ADVANCED DUAL-COATING TECHNOLOGY

XCU® dual coating technology graphic
  1. Less sulfur coating reduces N lock-off and delivers more N
  2. Coating integrity is maintained during transport, blending, bagging and application
  3. Outer layers consist of a thin coating of elemental sulfur and polymer wax, which work together to protect the inner polymer coating
  4. Inner layer consists of a thin, cross-linked polymer film that encapsulates and protects the urea granule
    SGN options – mini and regular

How It Works

XCU® how it works icon 1

Soil moisture penetrates the sulfur and polymer coatings.

Nitrogen (N) begins to dissolve creating pressure within the granule.

With previous-technology SCUs, this pressure cracked the coating, immediately releasing N (catastrophic release). The inner polymer coating of XCU® fertiliser results in a hybrid of diffusion-based release and catastrophic release, resulting in a more consistent release profile.

After the complete release of nutrients, the polymer coating eventually decomposes by microbial activity into naturally occurring soil elements.

PRODUCT BENEFITS

XCU® slow-release fertiliser has been widely used by superintendents, LCOs, municipal turf managers and professional landscapers to economically and efficiently promote a plant response of health, growth and color for up to 10 weeks per application.

  • Unique, durable coating provides gradual, consistent N release when needed to optimise nutrient uptake by the plant
  • Increased percentage of XCU® fertiliser in blends delivers increased value and improved nutrient uptake
  • Dual-coated technology provides up to 10 weeks of plant response
  • Fewer applications can reduce overall fertiliser expense, fuel costs and equipment upkeep; allows optimisation of labor
  • Highly flowable for ease of handling and consistent application
  • Environmentally responsible with low potential for nutrient leaching, denitrification, runoff or volatilisation

OPTIONS & FLEXIBILITY

XCU® fertiliser is available in sizes to fit a number of fertilisation programs.

XCU® product specifications chart

Only a portion of the N applied as conventional fertiliser is taken up by plants, but enhanced efficiency fertilisers (EEFs) increase N uptake. Increasing the XCU® fertiliser content in blends results in more efficient N use; the more XCU® fertiliser used, the better your blends work.
