POLYON® controlled-release fertilizer with its trademarked green color 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.

How it Works

Within a week of application, soil moisture penetrates the polymer coating through osmosis.

Encapsulated nutrients are dissolved, but not released.

Over time the dissolved nutrients slowly release through diffusion, in response to temperature and coating thickness.

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