Fertigation Fertilizer injection system Las Vegas, NV
LandTeck Inc installs and repairs any Fertigation fertilization system in Las Vegas, NV.
Fertilizing gives our efforts an extra boost by notably improving plant vigor and production. For backyard gardeners, that means the best tomatoes and most prolific fruits and flowers. In the case of commercial growing, it means healthier and higher crop yields that are critical to financial success.
Why use a fertilizer injector?
Fertilizing and watering are two of the most important tasks in a growing operation, and they are two of the most time-consuming tasks. Fertilizer injectors are a fast and accurate way to feed plants in a drip irrigation system. Because these injectors deliver liquid nutrients only where plants need it most – directly to the roots – fertilizer injectors are also the most efficient way to nourish plants.
When a drip irrigation system is in place, water soluble fertilizer can be directly dispersed through the system by way of a fertilizer injector. This is called fertigation. Incorporating a fertilizer injector into a drip irrigation system allows you to automate fertilizing as well as watering.
Note: You will need to use a water soluble fertilizer and you will want to filter downstream of the fertilizing unit. Both of these precautions will help minimize the risk of clogging drip emitters. In addition, you will always want to place a backflow preventer upstream of the unit to prevent fertilizer from backflowing into your water source.
How they work
Injectors remove a small amount of concentrated fertilizer from a stock tank and inject it into a water line. There are several types of fertilizer injectors. These include ones that use pressurization in the solution tank; venturi types that use a vacuum created by pressure differential across the inlet and outlet of the injector; and another that uses a water driven pump to move fertilizer from the solution tank into the system. These systems inject a precise amount of fertilizer solution to create a particular ratio of solution to water.
What the solution ratio means
For every part of stock solution, there are X parts of water, where "X" is determined by the injector ratio. For example, with a 1:100 ratio 1 part of stock solution is mixed with 99 parts of water, for a total of 100 parts of final solution. Often ratios are expressed as percents. For example, a 1:100 ratio equals a 1 percent solution.
Fertilizer injectors can come with fixed or variable solution ratios, and that choice will be determined by your project needs.
Which fertilizer injector is right for my project?
For homeowners, Ez-Flo units come in two categories, constant pressure (mainline installation) and non-constant pressure (installed after timers or zone valves). The non-constant pressure units are usually designed to connect to a hose bib and are normally a great fit for the backyard gardener. The downside to the non-constant pressure tanks is that you will normally connect one unit to each zone. So if you have 3 zones you would need 3 units. You can always move one unit from zone to zone as needed but if you have the system automated it can take away from some of automation as you have to remember to move the unit.
The constant pressure units are spliced directly into the main water source and offer more tank sizes. These tanks can feed multiple zones but are generally much more expensive and require some minor plumbing to install.
When units are built to withstand constant pressure, that means they can be installed before the valves and timer (but after a backflow preventer). It will be clearly stated in the product description if a unit is built for constant pressure or not.
Once you make the choice of which type of unit you want, you will next want to look at size. For example, let’s look at the ¾ gallon EZ-Flo unit with adjustable feed ratio of 1:100 to 1:1000.
At 1:100 the unit will empty of fertilizer after 75 gallons of water have passed through the unit.
At 1:1000 the unit will empty of fertilizer after 750 gallons of water have passed through the unit.
So as you can see, getting the right size and feed ratio is important.
