Central Kansas | We have run side by sides with ours, when we switched from 2x2 to in furrow we only changed one planter and finished in the same field. Saw differences there just mainly because 2x2 was running 28% and furrow was 10-34, quite a bit of difference. Then same way switching to dribble, have found that we see better early growth with nitrogen starter. As far as how the dribblers are setup, it is just black half inch hose that we made a fasterner for to the back left corner of the closing wheels so that tube runs about 1/2-3/4" of the ground and to the left of the trench approx. 2". Same principle as 2x2, just much simpler and cleaner, keeps the fert. away from anything metal. As far as setup, still run orifices about 18" up from the closing wheel leaving a little slack so you can change orifices w/o getting fert. on machine. The pumps are different for each planter, one is setup with two 5.5 gpm electric pumps and the other with an ace hyd., both use flow controllers. If you are going electric pumps, bear in mind that a 5.5 gpm pump will do about 8 gal/ac on a 12 row planter doing 5.5 mph @ 30-35psi. So if you need 20 gpm or more go with hyd. pump.
As far as big rains washing away fertilizer, we had two rains of 2" in 2 days after planting milo. One planter had the pump lay down in the last 15 acres so we went without to get done and 30 days post planting you could see to the exact guess row which row had starter and which didn't. I suppose it could wash away, but we are on fairly flat terrain so it may be minimal for us. Lets put it this way if I had 2x2 setup and someone else would maintain and repairs wouldn't stop planting, like be done instantaneously, I would not ever leave that, but that won't ever be the case.
To each his own,
