Mazzei Chemigation and Fertigation Technology equals greater efficiency at a lower cost...
Mazzei Injectors are high-efficiency, venturi-type, differential pressure injectors with internal mixing vanes. When a sufficient pressure difference exists between the inlet and outlet ports of the injector, a vacuum is created inside the injector body, which initiates suction of a liquid or gas through the suction port.
The Mazzei Injectors require a drop in pressure and flow of 20%, which is not usually a problem.
Mazzeis are perfect for agricultural use. They work by creating a vaccum that sucks the solution into the line.
Most importantly, do not oversize the injector! Call 1-800-345-3747 for assistance.
Ex. of Choosing Injector: 2 Acre Field with 3" Mainline to field. You hope to fertilze 1/4 acre to 1 acre at a time. Your flow is 9 gpm to 36 gpm. Using above chart, you need a 584. The 1078 would not work on your lower end flow rates.
Ex. of How you will USE your Injector: Pour dissolved water soluble fertilizer into container/bucket. Next, open 2 Parallel PVC Valves. Lastly, slowly start to close the brass gate valve. You will see Fertilizer flow up into clear tube.
GENERAL FERTILIZER APPLICATION RATES:
Apply 3.5 lbs of 20-20-20 per 1,000 feet per week. Once you have fruit set, apply 5 lbs. per 1,000' of 16-3-26 with Calcium. ** If you are growing Tomatoes & Peppers, you should spray them every week with Calcium Chelate at a rate of 2 oz per 1,000 feet.
REMEMBER!! More is not always better! I have killed more with fertilizer, than I have helped!
*** Soil Tests are recommended. Ask your Local Extension Agent about leaf samples and soil samples. They can also make specific recommendations to your region.
