The newest technique in lawn care is
fertigation. This is the process of
adding fertilizer to your irrigation water, and applying extremely
small amounts every time your sprinkler runs.
This is not a new process, we have been working with it since
1982. It started in greenhouse vegetables, moved on to
greenhouse ornamentals, then outdoor agriculture and then to golf
courses. But the equipment could cost tens of thousands of
dollars. What is new is equipment that is now available that
makes economic sense for homeowners. In addition, this method
of caring for your lawn is much more eco friendly because you use
less fertilizer and less water. When you get a gully washer
rain storm, it can wash away all your high priced time release
fertilizer sitting on the ground .(waiting for its time to release) When you
fertigate, the fertilizer goes down to the roots the same day you
run the sprinkler.
The most important thing you need to know about fertigation is that
no device or method is the best method for all applications.
Many companies have a single product type and try to convince you it
will work in your application. Some even have bigger devices
of the same design for bigger yards. But a device designed for a small yard is
not the most economical way to treat a big yard just by making the
device bigger. We have purchased, owned, used, tested, and
even taken apart nearly every device on the market to find out how
good they really are, and what they are really good at (or bad at).
Our conclusion: pick the best device for each type of application
and help our customers determine which of these is best for
them. We recommend and sell devices from several of the best
manufacturers, and we will honestly tell you why one would be your
best choice. We have also contracted with manufactures to
build units to our specifications under the trade name of Fertipump.
The second thing you need to understand is how much water and
fertilizer turf needs. Generally turf needs about 1 inch
of water per week. Having a rain gage so you know how much
free water you got is helpful, and a soil moisture sensor is the
most accurate way to know if you need to irrigate. One inch of
water is equal to 625 gallons per 1000 square feet. Turf also
needs 4-5 # of nitrogen per 1000 square feet per growing season.
Using this information, and knowing how big your yard is and what
your watering system is like we can accurately recommend the best
device for you. For individualized assistance, fill out the
yard survey and send it to us for a recommendation.
If you want to use 2 chemicals at the same time, test their
compatibility with a small quantity in the right proportions mixed
together. Many times concentrates can not be mixed with other
concentrates because they create dissolving problems. Diluting
both items with water can help solve this, but requires a pump with
a high injection rate and large stock tank. The High Flow
model is excellent for this purpose.
First determine the size of the injection pump needed for your
If you know the capacity of your sprinkler system in gallons per
(most residential systems on municipal water are about 10 gph)
10 gph of water needs a maximum of 38 ounces per hour of our
concentrated fertilizer. This allows you to put a weeks worth
of fertilizer on in one cycle of 1/4 inch of water.
number of sq ft to be fertilized X Rate divided by the hours per week
of irrigation = oz/hr. Rate = amount of fertilizer per
square foot per week. Our fertilizer rate is .01
example: 5000 sq ft, running 2 hours 2 times a week
5000 sq. ft of turf X .01= 50/4 hr. per week = 12.5 ounces
per hour average. The maximum would be twice that to put all the
fertilizer on in 1 watering.
