EZ Flo Automatic Fertigation

EZ-FLO makes fertilizer and supplement dispensing systems for use with any in-

ground irrigation system or with a standard water faucet (bib).  This technique of

applying products through the water is called "fertigation" and it saves on water

while significantly reducing the risk of fertilizer runoff.  Click here for more

information.

EZ-FLO now offers a full line of dispensing systems and landscape solutions for

municipal, commercial, school, residential and grower applications.

EZ-FLO was selected to dispense humates (carbon

enhanced bio-stimulants) and fertilizers in

The Rose Bowl™ during 2007 and on the

NFL Practice Field for the recent Pro Bowl in Hawaii

in 2008.

"Why Is It Important to Fertilize Responsibly™"

Fertigation

Fertigation is a process in which fertilizer is dissolved and distributed along with water in your drip or spray

irrigation system.  There is abundant research available that supports the superiority of fertigation as

compared to traditional fertilizing techniques.

Most fertigation systems for residential use require the use of liquid fertilizers since they are unable to

solublize (dissolve) higher concentration, water-soluble fertilizers.  Most companies that produce fertilizers

for fertigation produce liquid fertilizers since that is the only option that their dispensing units can handle.  

The drawback of liquids is that when

they are manufactured, they must be

pre-diluted with water to make them

weaker and less concentrated.

Producers do this because they

must keep the fertilizers in

suspension and can only do that

when N-P-K are at low concentration

levels. Therefore you rarely see a

balanced fertilizer's rating (N-P-K) in a liquid form above 20%.  If you see any N-P-K concentration levels

above 20%, it is most likely that this is primarily nitrogen in a urea-based form.

What does this all mean?

Well simply, you must use more of a liquid fertilizer to get the same fertilizing effect as when using a more

concentrated, water-soluble fertilizer.  This has the effect of driving up your final fertilizer cost.  This could

also cause you to refill your fertilizing system more often or to purchase additional system capacity to avoid

refilling as often.

In fertigation, you apply fertilizers based on a proportioning equation which is driven by the unit's inherent

design.  Some fertigation dispensers have proportioning ratios of 10:1 or 50:1.  This is appropriate since

they have already diluted their liquid fertilizers and therefore can inject or proportion at higher levels.  

Ultimately the goal is to find the right balance for a given landscape or application.

EZ-FLO technology has the ability to liquefy highly concentrated, water-soluble fertilizers and proportion

them into the irrigation water stream in extremely low doses.   It is a unique form of fertigation.  We call it

"Micro-Dosing".  And we have 9 US Patents to back up the technology!

Micro-Dosing simply means that an EZ-FLO fertigation unit can proportion fertilizers into the irrigation

water stream at very small parts per million (PPM) ratios.  Currently our main-line units proportion at rates

between 400:1 on the Fast Setting all the way to 15,000:1 on the slow setting.  

This is equivalent at full concentrate of 67 PPM at the "Slow" setting and 2,500  PPM at the "Fast" setting.  

When calculating PPM for a given fertilizer blend, you then need to multiply by the percentage

concentration (evidenced by the NPK numbers) for that fertilizer.  

For example, with our 25-15-10 blend, that means that we can proportion N down to 16 PPM.  If you use

our 10-20-30 blend, this means that the parts per million N is 7.  The Environmental Protection Agency

(EPA) of the US Government has set a standard for what is considered Clean Drinking Water in the US of

10 PPM for Nitrogen.  There are no such standards set for P or K.

The higher the concentration levels of the fertilizer (N-P-K), the more variability you can have in the final mix

when it comes out of the sprinkler head or drip emitter.  That's why we give you control over how fast the

fertilizer can be dispensed.

You can also think of this in a more meaningful context.  On the Slow setting, an EZ-FLO main-line unit

proportions fertilizer out at one twentieth of a teaspoon per gallon of water.  At the Fast setting, two

teaspoons.  Most people would agree that this is a very small amount.  But this small amount works since it

is applied every time with every drop of water.

Micro-Dosing has been proven to be agronomically superior for plants.
