Building side dresser

Now I come to the pump, im trying to figure out how big of a pump I need. Im thinking either electric or a pto 540 rpm pump.

Im thinking about aiming for 30 gallons per acre.

I used a dripless spray nozzle mount with the orifice and a hose barb where you would normally put the nozzle. The you can run the drop hose to put the nitrate behind the cultivator shovel closest to the row. I set mine up to drop on each side of the row.

A red ball setup is a good monitor for a plugged orifice.

I use an alectric pump that puts out up to 5 1/2 gal per minute.I was able to apply 60 GPA last summer.It fed 6 nozzles.I use this system for Starter fert also. However,I would caution/discourage from putting the tank on the cultivator. 28% is heavy(about 11 lbs/gal). put tanks on the tractor(front,or saddle) or pull a trailer.I simply duct tape the hose to the swewep closest to the row.I use the same pump system on both planter and cultivator.Just use a different orfice,depending on job/rate....Sorry,dont have any pics of cultivator or trailer setup.
