Fertilizer injection

Large residential yard, the homeowner wanted to know about fertilizer injection

I see two main types:
- passive flow systems that rely on flow through main pipe to pull water-soluable fertilizer from storage tank (EZflow)
- injection pumped using like a Stenner pump

Main line is 3". Using mostly RainBird popup impacts, MaxiPaws and 47/51s

Any pitfalls to using these injections? I've seen murmurings of nozzle fouling from the fertilizer.

Is ez flow even in business anymore? I installed about 10 of them and they are junk. The nipples for the injectors are plastic and break real easy.

I haven't done one in years. You should put an R.P. before it even in if local codes don't call for it.
I would not install one on a residential system again unless the landscape architect calls for one.

I would talk them out of it for the following reasons. Most systems I come across have poor uniformity either due to design or odd shaping of the lawn or both.

It would be difficult to determine the amount of fert one is putting down in a given area. The average person does not know how to calculate the proper amount of dry granular fert to apply to a given area much less liquid through a irrigation system.

i installed a mazi on my system just because i wanted to educate myself and be able to inject for various reasons. my yard is simple and basic. 5 zones, squares and rectangles. my coverage is pretty efficient, but my zones varied slightly in GPM. I spent the time to re-nozzle everything to match each zones GPM more closely. Otherwise one zone would suck the container dry while others pull very little. too many variables to even consider installing on a customers property. pay someone to spray your yard a couple times a year... and if its bugs your after, install a mosquito system.

but im very happy with my mazi personally.
i fertilize a few times a year with it, and inject cedar oil for pests during the summer months.

we also install a few fertile earth systems here and there, they seem to work ok, most customers use it with the low dose fertilizer/bug juice combo. verdict is still out, but im leaning towards it being an ok product for a small-medium system.

Is there zero overspray or run off from the property? I am talking about even some overshoot onto the streets or sidewalks. Only way I have ever had anything to do with fertilizer injection is in a production nursery or else an athletic field. Not on a residential property.

Agreed. A well designed SDI would be the only time I might consider injection, and even then only in Ag type scenario.

Here's a pdf of my design, this is a pretty much fresh install

Note that the lake is on the bottom, so that is suction line out to the lake.
