I have no clue but the system was installed professionally. I will have back flow problems addressed before installing any fertilization system.
I just joined & was hoping someone out there could provide me with information on how to determine the products needed to install a fertigation system into an existing irrigation system. I live in Oklahoma and there are no companies anywhere close that support this type of fertilizing I know I can purchased equipment from different sites, but have no idea what to purchase and then how to install. I have almost 4 acres to take care of and I was wondering if this would be a cheaper method than pay...
