What is the secret of Add-It®?
proportioning fertilizer injectors apply fertilizer through your drip
or conventional sprinkler irrigation system. It is easily installed into
any irrigation system, has no moving parts to wear out, and will not
effect your water pressure. Simply fill the additive tank on a regular
basis during the growing season, and the next time your irrigation
system operates, proportionately feed all your plant material. Add-It®
does all the work for you!
How does Add-It® work?
the main stream of water, through a unique design, Add-It® diverts a
small amount of water into the top of the additive tank, which then
forces the fertilizer, drawn from the bottom of the tank, into the flow
of water in the irrigation system. The incoming water does not mix with
the fertilizer concentrate in the tank. It’s amazing, yet simple. Fill
the tank on a regular basis, and each time you operate your drip or
conventional sprinkler irrigation system, a small amount of fertilizer
will be distributed evenly throughout your irrigation system. Unlike
other similar injectors on the market today, Add-It® is completely
proportioning, in other words, the concentration of fertilizer being
dispensed will be the same fromstart to finish!
Where do I use Add-It®?
the many sizes and configurations Add-It® is available in, its easy to
see that there are many applications in the agricultural, commercial,
greenhouse, golf course, and residential areas where they can be
utilized. Add-It® can be installed after an individual valve, or before a
manifold of valves under constant pressure, up to 125 PSI. There is no
pressure loss and there are no moving parts to wear out. Add-It® does
all the work for you.
What size Add-It® do I need?
determining the best size Add-It for your particular application, you
must first decide how often you want to refill the injector. From the
Add-It® chart on the four page fertilizer injector brochure, choose a
unit depending on how much fertilizer you need to apply, and what your
flow rate is through your irrigation system. Also of great importance is
the minimum flow rate (GPM) going through the irrigation system where
the Add-It® is being installed. Add-It® only requires 10 PSI and is
preset at a ratio of 200 parts water to 1 part fertilizer or additive
For example, if you are fertilizing an area of about 1,000
square feet, you will need to use approximately one gallon of liquids
fertilizer, you’ll want to install an Add-It® with at least a one gallon
capacity (or larger). Next, determine how many gallons per minute (GPM)
flow through your irrigation system. You can easily calculate the flow
rate by adding up all the drip emitters or sprinklers on each system,
thereby giving you a total flow rate. Keep in mind, emitters in a drip
irrigation system are rated in gallons per hour, where as conventional
sprinklers are rated in gallons per minute.
What type of fertilizer do I use in the Add-It?
shrubs, lawns, and most other plants will best absorb fertilizer when
it’s in liquid form. Why? Because liquid fertilizers not only work
faster than dry pellets or granules, they move through the soil and are
more readily available for absorption by the plant material. Add-It®
injectors apply liquid fertilizer in small even doses to produce the
most superior application possible! You can use fertilizers like Neptunes Harvest or Grow
More®, when pre-blended with water at a ratio of one pound of dry
additive to one gallon of water. You may also want to consider adding a
wetting agent to breakup compacted soils, micro-nutrients and Vitamin
Institute’s containing vitamins and hormones for healthier
plants, and vitamin B-1 when transplanting trees or shrubs.
