A venturi fertilizer injector lets you feed crops through your drip irrigation system. Water flows through a narrow throat, speeds up and creates suction. That suction draws liquid fertilizer from a separate tank into the line. A valve controls how much is drawn in. It has no motor and needs no power. This 2-inch unit suits greenhouse and open-field drip systems for tomatoes, peppers, cucumbers, watermelon and other vegetables.
Product details
- Type: venturi injector for fertigation
- Size: 2 inch
- Power: none; driven by water pressure
- Control: valve to adjust injection rate
- Uses: liquid or fully dissolved fertilizers in drip systems
How to set up and use
- Fit the injector on the mainline after the pump, often on a bypass with a valve so you can control the pressure drop.
- Put the suction tube in your fertilizer tank with a filter on the end.
- Fully dissolve fertilizer before injecting; undissolved grains block drippers.
- Run plain water for a few minutes before and after fertigation to flush the lines.
Tips for best results
- Fit a screen or disc filter after the injector.
- Start with a low rate and check the drip water.
- Use water-soluble fertilizers made for fertigation.
- Rinse the injector with clean water after use.
Frequently asked questions
Does it need electricity?
No. It works on the water pressure from your pump or tank.
Why is it not sucking fertilizer?
There is not enough pressure difference across the injector. Install it on a bypass and partly close the main valve.
Can I use granular NPK?
Only if it fully dissolves. Water-soluble fertilizers are best to avoid blocked drippers.
Will a 2 inch injector fit my system?
It suits 2-inch mainlines. Use reducers for other pipe sizes and check that your pump flow is enough.
