The Grass is Greener with Lawn Fertigation Systems

Utilize your existing sprinkler and watering systems to fertilize and irrigate at the same time -- known as fertigation or chemigation -- to automatically nourish and beautify lawns.

With the right amount of water, the agricultural technique can thoroughly activate fertilizer at the desired root depth

For home or commercial property owners who want healthy green lawns and landscapes without tedious fertilizing or expensive professional application, the answer is the Lawn Fertigation System. This hot new lawn and yard care product finally brings to homeowners what has been an agricultural trade secret for over 30 years -- the ability to "fertigate," or simultaneously fertilize and irrigate, using existing sprinkler or watering systems.

Offered by IIT, a division of Agri-Inject ( -- the agricultural leader in liquid nutrient application -- the system easily keeps lawns and landscapes greener and healthier than traditional fertilizing methods when paired with a watering system.

While spreading traditional solid fertilizers can bring out an initial burst of color in greenery, it can also "overdose" lawns and plants, causing "burning" or "streaking," followed by long periods of under-nourishment as the nutrition disappears. The same is true of direct spray liquid fertilizers.

In contrast, the Agri-Inject's product injects precisely controlled amounts of liquid fertilizer into existing sprinkler or watering systems, mixing it with tens or hundreds of gallons of water. This essentially "spoon feeds" lawns and landscapes with the right dose of nutrients at the right time, allowing the water to carry needed nutrition to grass and plant roots where it can best be used.

"With the right amount of water, the agricultural technique can thoroughly activate fertilizer at the desired root depth," adds Gary Newton, who coined the terms fertigation and chemigation after experimenting with the techniques in the late 60s. Newton founded Agri-Inject in 1982 to meet the huge demand for such equipment.

Fertigation systems such as Agri-Inject's can not only replenish quickly used major nutrients such as nitrogen, but also economically deliver important minor nutrients such as sulfur, boron and magnesium, or even micro nutrients such as manganese, zinc, and copper. Custom seasonal nutrient blends can thus be delivered at the best time and in the right doses to keep lawns and gardens looking their best year round.

Because the product's state-of-the-art diaphragm chemical metering pump with micrometer adjustment is so accurate, it eliminates both over and under-fertilization.

The process is particularly effortless when paired with an automatic sprinkler system. Basically, just pour any liquid fertilizer into the portable tank, set the correct ratio, and the automatic sprinkler does the rest. For the average home, a fertilizer supply will typically last 3-6 months, during which time the grass and yard are greener with nothing extra for the homeowner to do.

Agri-Inject's Lawn Fertigation Systems are simple enough for homeowners to self-install, yet robust enough to be used by municipalities or commercial property owners of up to 20 acres.
