I am getting tired of guessing how much fertilizer that I am applying. Does anybody have any ideas on a simple rate controll system. I am applying 20-35 gal/ac of liquid fert with a John Blue double piston pump on a 40 ft. Concord airseeder.
I would prefer to adjust the rate on the go but if that is too expensive just to know the accurate gal/ac. would be beneficial.
