Fertilizer tanks are used to mix fertilizer with water. The working principle is that a sufficient amount of fertilizer is placed in the tank, the fertilizer is dissolved there and injected into the irrigation system.
For fertilization application, the required amount of granular or powder fertilizers that are easily soluble in water is placed in the fertilizer tank. The lid of the fertilizer tank is closed tightly, the large valve is turned down a little and the fertilization valves are opened.
After fertilization, water is continued until there is no more fertilized water in the pipes.
