Automatic fertilizer injector

Venturiwith controller

Venturi fertilizer injectors are installed in parallel with the control valve of the water supply pipe at the entrance of the micro-irrigation system or the irrigation area. When using, the control valve is closed down, resulting in a certain pressure difference before and after the control valve, so that the water flows smoothly through the branch pipe where the Venturi fertilizer applicator is installed. Using the vacuum suction generated by the water flow through the Venturi tube, the fertilizer solution is evenly drawn into the pipe system from the open fertilizer bucket for fertilization.
