How It Works

 How Add-It™ Proportional Automatic Fertilizer Injectors Operate The fertilizer additive is placed into the Add-It™ Automatic Proportional Automatic Fertilizer Injector canister and it does not become diluted as the irrigation system operates. Through a unique hydraulic design, a small amount of water is diverted from the main line flowing through the unit canister and then is forced into the top. A slight pressure differential is created between the inlet and the outlet drawing the fertilizer out from the bottom of the canister. The water coming into the top of the Add-It™ Proportional Automatic Fertilizer Injector canister is lighter than the solution of fertilizer in it. The liquid fertilizer solution has a heavier specific gravity then the water. Therefore, the water sits on top of the solution of fertilizer and not mixing with it. The distribution of the fertilizer is the same from beginning to end. After the fertilizer solution has been dispensed, the canister will contain only water.
