VENTURI INJECTORS FOR CHEMIGATION/FERTIGATION AND FOR AIRJECTION
Injecting chemicals or fertilizers into a pressurized irrigation system is the most common application for Mazzei venturi injectors in agriculture. Mazzei pioneered this simple-to-use and easy to install solution more than 35 years ago. Today Mazzei venturi injectors are still the benchmark in chemigation and fertigation.
Now, in addition to venturi injectors for chemigation and fertigation, Mazzei offers a line of AirJection venturi injectors used to increase plant health and vitality by adding atmospheric air, via a drip irrigation system, directly to plant roots resulting in boosted soil microbial activity. Instead of being temporarily drowned in excess water during irrigation, plant roots have immediate access to critical air necessary for growth which produces improved yields.
High crop yield and soil health continue to be major agricultural concerns, and to attain this, plowing continues to be the most accepted method of introducing air to root systems. Now there is Mazzei AirJection irrigation technology for aerating root systems… basically, plowing without a plow. It draws air into irrigation water through Mazzei AirJection venturi injectors. The air, in the form of micro-bubbles in the water stream, is then delivered directly to the root system by way of subsurface drip irrigation. This puts less stress on the plant giving it the ability to absorb water, air and soil nutrients simultaneously. California State University, Fresno and the Center for Irrigation Technology have conducted numerous trials since 2000 on Mazzei AirJection irrigation. Data from university-led trials and grower installations has shown that AirJection irrigation achieves yield increases due to efficiency of both water and fertilizer use which are greatly enhanced through AirJection irrigation.
For precise chemical and fertilizer applications into irrigation systems… Mazzei is the low cost solution. Mazzei injectors are patented, high-efficiency Venturi injectors with internal mixing vanes. They are used worldwide for injecting gases and liquids such as fertilizers, pesticides, chlorine, and other chemicals into pressurized water systems. Mazzei injectors operate over a wide range of pressures and require only a minimal pressure differential between the inlet and outlet sides to initiate a vacuum at the suction port. Mazzei venturi injectors do not require external power to operate but a small booster pump may be used to produce the minimal differential pressure required.
