We have on hand liquid fertilizer tanks in 55 and 75 gallon size. Other sizes available upon request. We can install complete new liquid systems. Our adjustable tank mounts are factory built for our planters. We include a (made in the U.S.A.) high quality 12v pump with regulating valve and gauge. Tank will have a shut off valve installed. In-line orifices run to each row to keep the flow even. We can either run the hose behind the planter press wheels or install double disc openers to inject the fertilizer in a 2"x2", that is 2" off to the side and 2" below the soil surface, where the seed needs it. This setup will insure your seed gets off to a good start!
