Harrell’s is the exclusive eastern formulator and a leading distributor of Polyon Controlled-Release Fertilizer, which has been used by turf professionals for nearly 20 years. Its patented Reactive Layers Coating technology is backed by many years of basic and applied research, both in laboratories and field applications on commercial turf and residential lawns. Nitrogen is released gradually and consistently via temperature-controlled diffusion and it is not affected by moisture. The controlled release of nutrients helps professional turf managers achieve green, healthy turf and lawns for up to seven months. And, because nutrients are released gradually throughout the growth cycle, there is less nutrient loss to the environment.
