To connect it to the main irrigation line, it has coupling (straight through) that you will insert in the mainline behind the valves. Two tubes branch off the coupling and join it to the tank.It works with the venturi principle to meter fertilizer inside the tank while the water flows from the coupling. With an increase in water flow, there will be a corresponding increase in the fertilizer that moves out of the tank.

  • The injector must have a backflow valve that will prevent the fertilizer from contaminating the central water supply system. It should also have an anti- siphon valve that will prevent irrigation water from flowing back into the fertilizer tank.
  • It is prudent always carefully to read the injector’s manual before starting to set it up. That will save you a lot of time and enable you to have it ready faster.

Factors to Consider Before Purchasing The Best Fertilizer Injector for Drip Irrigation 

Flow Rate of the Fertilizer Injector 

Flow Rate of the Fertilizer Injector

The flow rate is when the mix of water and the water-soluble fertilizer will leave the injectors tank or reservoir. This plays a significant role in how the injector injects fertilizer into the water supply and the plants.You should ensure you check if this rate can be adjusted on your injector. And whether it would be unsuitable for you before buying. You can calculate the flow rate of your irrigation system to know which injector to choose.

Budget of the fertilizer injector: Can You Afford it 

Your budget determines most of the things you can afford and those that you eventually buy. That is the same with injectors as well. While there are good deals out there, you should be wary of the overly cheap products. As much as they will save you money, cheap products might have a few drawbacks that will make you regret buying them. That is why you need to ensure you go for an injector that is well within your budget to avoid future regret or financial strain. It would best to remember that not all expensive things are worth the money. So again, don’t blindly buy expensive injectors even if you can afford them. Instead, weigh all the features and relate them to the price.

Durability: Will It Stand the Test of Time 

While the amount of time a fertilizer injector should last will depend on how carefully you handle it, you still need it to be durable. That means the tank having a body that is resistant to the elements or wear and tear.

Injectors will deteriorate with every use, but it doesn’t have to be that fast. Fortunately, the injectors on our list are proven to be long-lasting as they are made of quality material. Always remember to check whether the injector has durable material before buying it.

Tank Capacity of the fertilizer injector: How Much Can It Hold 

Tank Capacity of the fertilizer injector How Much Can It Hold

Except for one injector, all the others have tanks. You should consider the tank capacity before purchasing an injector since it will determine the amount of time you will spend refilling it. It also directly corresponds to the amount of fertilizer you can mix.

Injectors with larger tanks will obviously have the upper hand and will save you lots of time. That is why this should be among the things to look out for.

Ease of Use: How Easy Is it to use 

The ease of use applies not only to fertilizer injectors but also to any other equipment you buy. Some injectors are relatively challenging to use, thanks to the features that come with them.

To ensure you avoid this, you should ensure you get one that will give you an easier time using it. That means getting an injector that has a simple design that you can easily wrap your head around.

Size of the fertilizer injector 

Size of the fertilizer injector

How large will your operation be? It is essential to ask yourself this question before purchasing an injector. If you are doing it on a large scale, you will need a larger injector with a higher capacity and flow rate.

If, on the other hand, all you need is an injector for your small garden in your backyard, a small one will suffice.

4. Can I use Organic Fertilizer?

You can use organic fertilizer with a drip irrigation system so long as the fertilizer is water-soluble.
