Fertilizer Injectors

Fertilizer injectors are used to apply water-soluble fertilizers, pesticides, nutrient solutions, wetting agents, and mineral acids to plants during crop production. They are a vital part of modern greenhouse or nursery operations. By sending nutrients in a liquid form directly to the roots of the plants, fertilizer injectors are a fast and accurate way to feed an entire garden.

When considering a fertilizer injector, consider the following:

  • The size of your operation
  • Water flow rate
  • Size of stock tank

How fertilizer injectors work

Injectors that attach to a faucet and use water pressure to mix your solutions with the hose water are best for smaller spaces. They draw most efficiently from small stock containers, making them ideal for smaller greenhouses.

Positive displacement injectors offer more control over the amount of injected chemicals distributed, making them more efficient for larger farms and growing areas. High pressure injectors are best for large commercial applications.

One of the most important decisions you can make is to choose the right injector for your flow rate. Flow rate is measured in gallons per minute (GPM), which is the rate water flows through water lines. Flow rate can be determined by pipe size and water pressure, which is measured in pounds of pressure per second or PSI.

All fertilizer injectors draw from a stock tank. Whether you are using a 5-gallon bucket or a commercial container, make sure that your injector is able to draw efficiently the stock container you have chosen.
