Introduction to Wellcoat 3 – Slow Release Fertilizer
Wellcoat 3 – Slow Release Fertilizer consists of high quality nutrients in granular form encapsulated in resin coating. Once the granules come into contact with moisture in the growing media, the granules will begin to absorb water vapour through microscopic pores in the coating. This moisture content will slowly dissolve the nutrient’s content, which then diffuse continuously into the root zone.
The release rate is controlled by the soil temperature which determines the rate of water vapour penetration and fertilizer diffusion. As temperature increases, the release rates increases and vice versa. The level of water retention, pH values, microbial activity or exchange capacity of the soil does not significantly affect the release rate.
How Does It Work?
The release of nutrients from Wellcoat 3 is controlled by its unique polymer coating which is imposed over granular fertilizers. The insoluble polymer coating prevents instant dissolution of the solid core. Nutrients are released in a slow and gradual manner in aims to to match the plants’ needs.
