makes the FertiGator unique is its ability to precisely
control how much fertilizer goes out to each zone.
are three types of controllers distinguished by the number of
zones and injectors it can control.
the Number of Zones
you have more than 8 zones on your property you can easily
link additional controllers to handle 16, 24 or 32 zones. All
you need to do is purchase an additional controller of the
right type which includes a connector to link them together.
FertiGator AR-3 Controller
For complex properties we recommend using the FertiGator AR-3
Controller. The AR-3 controller is the most exciting
innovation in the entire field of non-agricultural fertigation.
The FertiGator AR-3 is a 40-zone controller that independently
controls three different injectors. It can be used with any
combination of three M or Pro Series single or double
There is nothing that the AR-3 Can't do! The AR-3 can deliver
turf fertilizer only to the turf zones, flower food only to
the garden zones and other specialty lawn care products to
where they are needed most.
Using three double injectors working in tandem, the AR-3 can
deliver up to six times the fertilizer that the M1 Kit can
deliver. By linking more than one AR-3 there is virtually no
limit to the size or complexity of property you can manage!
The controller is wired into the sprinkler system controller
and is usually mounted beside it. When a sprinkler zone
activates, the FertiGator reads this and causes the injector
to pulse which sends fertilizer out into the line. The
FertiGator injects just one milliliter (one cubic centimeter)
Each irrigation zone on the controller is programmed to
deliver precisely the right amount of fertilizer for that
zone. Injection rates may vary from as high as 19 pulses every
two minutes to one pulse every eight minutes. A zone can also
be programmed at 0 pulses if necessary.
The top row of green lights on the FertiGator 8-zone
controller represents the zones. They are also used to program
the pulse period. The controller tells the FertiGator injector
when to pulse based on the settings for that zone. The
settings range from 0 to 19 for each zone and are represented
by the second row of lights on the controller. The 0 (red,
first light) setting does not deliver any fertilizer. The 19
setting is the maximum setting. The FertiGator injector
delivers the number of milliliters of fertilizer displayed
(from 0 to 19) evenly spaced during the pulse period. The
pulse period is the amount of time it takes to deliver the
specified number of pulses. For example, if the zone is set at
10 pulses and the pulse period is set at 3, the FertiGator
will pulse 10 times every 3 minutes that the zone is open,
every time you water.
You will notice gradual greening of your lawn and vegetation
instead of the usual surge of growth. This is desired for the
health of your lawn and landscape. The FertiGator can regulate
foliar growth. If after a month or so of use you feel you want
the lawn to be greener you can increase the pulse rate on all
or some of your zones. If on the other hand you wish to mow
your lawn less, you can reduce the pulse setting on some or
all of the zones. The FertiGator gives you maximum flexibility
to balance your desired growth with your desired look.
FertiGator controllers have non-volatile memory, which means
that they can be turned off without losing the program that
was entered, even for an entire winter.
