South-central Nebraska | Ron,
I run a DMI 2800. I was running 47 gallons of fert solution preplant 9 mph at 75-80 psi. I run coulters 7.5" off of the row a good 4 inches deep. A jet injects liquid behind it. If it is in line with the coulter, splatter is minimal except at the ends where I am often dropping it while kicking on the pump.
We currently fill with a two inch fill. Could go to a three because we have two points of entry into the tank. I suppose 10-15 minutes per fill. Gives a little time to get out and stretch, adjust nozzles, check over the machine, get a drink etc.
The DMI uses a hydraulic down pressure system that keeps the wings penetrating pretty well. Much better than just wings relying on gravity.
Yes, the fertilizer is corrosive. If I come in at night and will not be fertilizing the next morning I often rinse things off. Between preplant and sidedress it gets a good cleaning. After season we repaint the coulters with spray paint.
