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-
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-
weaker and less concentrated.
Producers do this because they
must keep the fertilizers in
suspension and can only do that
when N-
levels. Therefore you rarely see a
balanced fertilizer's rating (N-
above 20%, it is most likely that this is primarily nitrogen in a urea-
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-
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.

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-

fertilizer can be dispensed.
You can also think of this in a more meaningful context. On the Slow setting, an EZ-
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.
