Mazzei Airjection

A Proven Method of Increasing Crop Production in Subsurface Drip Applications
Available in seven models 1/2", two models 3/4" (Rainbow series), one 2" and one 3"
10% + increase in yields as compared to conventional drip*
50% increase in root mass – healthy and more vital plant
Less stress on plant as the plant is able to absorb water, air and soil nutrients simultaneously during the irrigation cycle
May hasten maturity in the plant allowing harvest to come earlier
Ease of operation
Added benefits for organic growers

* Increase in yields based on results obtained from commercial farming andstudy performed by CIT at CSU Fresno

Why AirJection
Aside from soil, two basic ingredients necessary to root systems in farming are air and water.
Mazzei AirJection Irrigation improves aerobic activity in the soil and increases root respiration. Inadequate soil aeration reduces the rate of water and mineral absorption by the roots. Saturated soils will trap metabolites, ethylene and carbon dioxide in the root zone, concentrations of which can seriously affect the rate of growth and size of the plant. Oxygen is also necessary for the survival of beneficial soil micro-organisms that aid in improving soil physical properties and processes such as nitrification and ammonification. Clay soils by nature are depleted of oxygen more rapidly than soils high in sand content.
Mazzei AirJection Irrigation provides needed oxygen directly to the root zone during irrigation. The Mazzei AirJection Irrigation unit is calibrated to deliver the proper air to water ratio. Mazzei AirJection Irrigation is designed to work in sub-surface drip irrigation (SSDI) applications.
To ensure uniform distribution of the air, the unit is typically installed at the drip tape or dripper line sub main and will function as a pressure reducer.

Advantages
10-39% increases in production as indicated by the tests
done with bell peppers at a commercial farming operation.
50% larger root mass, and a healthier root zone due to an
increase in soil microbial activity.
Improve plant canopy size and reduce damage by the sun.
Tests performed with an infrared thermometer indicate
lower levels of stress on airjected plants as compared to plants irrigated with conventional drip.
Results show less yield loss due to stress.
Beneficial to clay soils where oxygen is easily depleted.
Added benefits for growers of organic produce. Reduces the
need for additional soil amendments and organic fertilizers.
Plant stress is minimized; Plants may produce earlier.
Reduce effects of soil crusting. Reduce tilling due to the
immediate injection of air under the surface of the berm.
Micro-bubbles produced by the Mazzei AirJection Irrigation
unit have a cleaning effect on the inner walls of the drip tape and tubing keeping particulates in suspension and reducing the chance of plugging.
Injector constructed of rugged PVDF thermo-plastic carries
5 year warranty.
Single valve operation makes it easy to operate.
Injector acts as a pressure regulating valve.
Substantial returns with minimal capital and operating
costs.
Less stress on plant as the plant is able to absorb water, air
and soil nutrients
simultaneously during the irrigation cycle.
Any crop utilizing SSDI should benefit from the Mazzei
AirJection Irrigation system.
