Mazzei Solutions for Irrigation
Injecting chemicals into a pressurized irrigation system (chemigation) is the most common application for Mazzei Venturi injectors in agriculture. Mazzei pioneered this simple-to-use and easy to install solution more than 30 years ago. Today Mazzei Venturi injectors are still the benchmark in chemigation.
Now, in addition to Venturi injectors for chemigation, 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, is then delivered directly to the root system by way of subsurface drip irrigation. This allows less stress on the plant due to the ability for the plant 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.
Precise chemical applications for 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.
