POLYON® controlled-release fertiliser with its trademarked green colour is backed by years of research, and for decades has been the market leader in the turf and ornamental markets. The key to its performance is the Reactive Layers Coating technology which meters out nutrients via diffusion, regulated by soil temperature and coating thickness.

Reactive Layers Coating Technology



Polyon- How It Works

  1. Within a week of application, soil moisture penetrates the polymer coating through osmosis.
  2. Encapsulated nutrients are dissolved, but not released.
  3. Over time the dissolved nutrients slowly release through diffusion, in response to temperature and coating thickness.
  4. After the complete release of nutrients, the polymer coating eventually decomposes by microbial activity into naturally occurring elements.


POLYON® controlled-release fertiliser is formulated for turf, landscape and nursery applications.

  • Temperature-driven nutrient release, not affected by excess moisture or rainfall
  • Precise, predictable nutrition; minimal surge growth and low burn potential
  • Fewer applications save time and offer the ability to reallocate labor resources to other tasks
  • Greener, healthier turfgrass for the ultimate playing surface or lawn
  • Dust-free handling and long shelf life due to durable coatin
  • Environmentally responsible with low potential for nutrient leaching, denitrification, runoff or volatilisation
