| Polyon® is the key timed-release ingredient in fertilizers manufactured by Pursell Industries of Sylacauga, Alabama. Gardeners who use plant foods containing Polyon-coated nutrients enjoy season-long feeding with one application. Because fertilizers containing Polyon are granular, you dont have to mix or pour messy liquid fertilizer again and again. Instead, you can just spread fertilizer with Polyon and forget about it. It makes gardening easy. Polyon is distinguished as a unique green coating that bonds to fertilizer granules. If its not green, its not Polyon. ![]() Depending on the thickness of the coating, the green Polyon-coated granules are timed to release for 2, 3, 6, or 9 months (measured at *72° F (+22° C) soil temperature). The length of timed-release varies depending on each products formula. That means that you can choose a fertilizer that lasts as long as you need it. This steady, predictable release feeds plants slowly, as they can use it. ![]() The chart below shows the advantage of fertilizers containing Polyon-coated nitrogen compared to other types of nitrogen. (Nitrogen is the most important--and most expensive--ingredient in most fertilizers). Pound per pound, fertilizers containing Polyon-coated nitrogen are a better value than fertilizers that release all of their nitrogen quickly, only to be washed away. Polyons timed-release approach to feeding reduces waste, fertilizer runoff or pollution, and saves you time and money. You will find that most plant foods containing Polyon-coated nutrients feed plants both now and later, so some of the granules in the bag are not coated at all. This is by design. The thoughtful mix of both fast and timed-release plant food provides some instant feeding and planned, long-lasting nutrition.
