Does anyone have any experience or knowledge on these/ this topic? Im looking at installing a EZ Flo fertilizer injector, http://ezfloinjection.com Ive been researching, but haven't been able to really find out much definitive information. Is there any benefit to having a system like this? My main thoughts are that it would evenly distribute the fertilizer through the sprinkler heads, versus me using a broadcast spreader and trying to push in straight lines. I have a large area that I water and fertilize, approximately 2 acres. I have been following the Randy Lemmon schedule since last summer. The EZ FLO uses either liquid fertilizer or fertilizer that is water soluble, which I can't tell if any on Lemmon's recommendation are.
