How Add-It™ Proportional Automatic Fertilizer Injectors Operate

The fertilizer additive is placed into the fertilizer injector tank. As the irrigation system operates, a small amount of water is diverted from the main line flowing through the fertilizer injector into the top of the tank by utilizing a specially designed. color-coded, flow controlled nozzle.
Since the specific gravity of the fertilizer solution in the bottom of the tank is greater than that of the added water, the water floats on top of the fertilizer solution and does not mix with it, so the concentration of the fertilizer solution remains the same from the beginning to the end of the cycle. The slight pressure differential created between the inlet and outlet draws the fertilizer solution from the bottom of the tank until all that is left in the tank is water.
