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 irrigation 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 injectors do not require external power to operate, but in some situations, a small booster pump may be necessary to produce the minimal differential pressure required. Today, Mazzei venturi injectors are the benchmark in chemigation and fertigation.
For generations, tillage has been the most accepted method of introducing air to the soil’s root zone in an effort to enhance crop yields. Today, Mazzei AirJection irrigation technology injects air directly into the soil. In effect, allowing for plowing without a plow. AirJection draws air into subsurface drip irrigation water through Mazzei injectors. The air, in the form of tiny bubbles in the water stream, is then delivered directly to the root system. This puts less stress on the plant and gives it the ability to absorb water and air while boosting soil microbial activity.
The Center for Irrigation Technology at California State University, Fresno, and other universities around the world, have conducted numerous trials since 2000 on aeration in subsurface drip irrigation using AirJection. Data from university-led trials and grower installations has shown that aerated drip irrigation achieves yield increases and quality improvements by improving soil health and the efficiency of both water and fertilizer use.
Automatic Fertigation Systems are the latest approach to precisely and efficiently blending liquid fertilizer and irrigation water. Mazzei venturi injectors are at the heart of various manufacturers’ automatic fertigation systems. With Mazzei injectors in a system, nutrients are thoroughly mixed and well distributed throughout the irrigation water.
