EZ-FLO developed a patented line of fertilizer proportioning systems that distributes not only liquid fertilizers, but can distribute more concentrated, water-solubles.

These systems work by creating differential flow pressures. Therefore EZ-FLO can feed both low volume drip and higher volume spray irrigation zones on the same system without a change in nozzles or settings.

Virtually no Pressure loss; Systems operate down to 5 PSI and 2.5 gallons per minute flow.

Technical Information

EZ-FLO Fertigation technology has been in development over the last ten years. As of 2005, EZ-FLO has received 8 issued US Patents and 2 International Patents covering its unique fluid flow technologies and has tens of thousands of units operating in actual field use. Our patents cover the connection couplings as well as the flow process whereby fertilizer is accurately proportioned in the tank cap for release to the irrigation water stream.

One of the unique attributes of an EZ-FLO system is its ability to precisely proportion fertilizer concentrate into a water stream in an extremely accurate manner. We call this "Micro-Dosing".  Not only is the amount of fertilizer concentrate proportioned accurately but the individual fertilizer elements of N-P-K are also in consistent ratios when exiting the irrigation system from beginning of the fill cycle to the end of the cycle. 

Below are actual photographs of a clear tank going through a complete "full to empty" cycle.

Many people erroneously assume that fertilizer in the EZ-FLO system is simply diluted as it goes through an entire cycle. However as can be seen above, dilution does not actually occur. EZ-FLO’s patented flow technologies effectively create an “invisible bladder” that separates the clear water entering the tank from the fertilizer concentrate at the bottom of the tank. As clear water is introduced into the tank, it arrives in a number of areas. Port water inlets at the top of the tank create a clear layer of water that separates it from the fertilizer concentrate. Additionally a micro-jet agitation nozzle at the bottom of the tank gently agitates the fertilizer concentrate keeping the resulting semi-dissolved concentrate at even concentration levels leaving the tank. As a result there is no effective dilution of the suspended N-P-K.

EZ-FLO technology results in a level application rate and there is no concentration/dilution "spike" as occurs in other proportioning systems.

Independent Testing Results

EZ-FLO secured the testing services of the JR Peters Laboratory (a Scotts Miracle-GRO Company affiliate) to document the consistency of the N-P-K release using EZ-FLO technology. The result of this independent lab testing is shown graphically above during the "full to empty" cycle.  As can be seen, there is no initial spike in parts per million (PPM) as occurs with other mixing systems. Additionally the N-P-K parts per million remains relatively constant until the tank evacuates at the end of the cycle. Only then do the parts per million fall off, but that is in the last 5-10% of the cycle when the tank is almost empty of fertilizer concentrate.
