Hello, I'm new to fertigation and could use some help! I would like to add a fertigation system to my existing irrigation system but don't understand how big (Gal.) of unit I need? As well I don't know what information I need to post for help. I have 1.5 acres of TURF,trees and flower beds (simple landscaping) that I water using surface irrigation water, I utilize a 2hp. goulds irrigator booster pump that supplies 4 zones, (14 Rainbird Maxi-Paws ea. zone). I would guess the pressure to be around...
