How Wellcoat Works
Wellcoat fertilizers consist of high-quality nutrients in granular form encapsulated in a resin coating. As soon as the granules come into contact with moisture in the growing media (above 25% w/w), the granules begin to absorb water vapor through microscopic pores in the coating. This moisture slowly dissolves the nutrient's content, which then diffuses continuously into the root zone.
The release rate is controlled by the soil temperature, which determines the rate of water vapor penetration and fertilizer diffusion. As temperature rises, the release rate increases, and vice versa. The level of water retention, pH values, microbial activity or the exchange capacity of the soil does not significantly affect the release rate.
