The Venturi fertilizer applicator can be installed in parallel with the water supply pipe control valve of an irrigation system. During use, adjust the valve on the main water pipe to create an appropriate pressure difference before and after it. Alternatively, it can be directly connected in series within the pipeline, utilizing the vacuum and atmospheric pressure generated by the Venturi fertilizer applicator to uniformly draw fertilizer solution from an open fertilizer bucket into the pipeline system for fertilization. The Venturi fertilizer applicator features low cost, ease of use, and no need for external power, among other characteristics. Additionally, the Venturi filter straw kit includes a designed control valve that allows for adjustment and control of the suction volume.

1. The Venturi fertilizer injector is installed in parallel with the water supply control valve at the inlet of the irrigation zone of the irrigation system. During use, partially close the control valve to create a pressure difference across it, allowing the fertilizer dissolved in water to be drawn into the Venturi fertilizer injector and then flow into the water supply pipeline.

2. Utilizing the vacuum suction generated by water flowing through the Venturi tube, the fertilizer solution is uniformly drawn from an open fertilizer bucket into the pipeline system for fertilization. The Venturi fertilizer applicator makes operation more convenient and straightforward.

3. If the fertilizer concentration is stable, no external power is required, saving more time and resources.

4. The main body is formed in one piece with a reasonable structure.

5. Utilizing the siphon principle, it easily draws various liquid fertilizers and injects them into the irrigation pipeline, ensuring uniform water and fertilizer irrigation for various crops.

1. It can be easily connected to the main pipeline when used with the fertilizer injector kit.

2. The inlet and outlet are external threaded joints for easy connection.

3. Select the corresponding specification of the fertilizer injector based on the crops and irrigation area. Too large or too small is not conducive to effective fertilization.

4. If uncertain, choose a smaller specification and install it in parallel with the main pipeline using the fertilizer injection kit. Control the water flow by adjusting the valve to achieve the fertilization purpose. If the fertilizer injector is determined to be too small, reduce the water flow via the valve and extend the time to achieve the fertilization goal.
