I'm in the same boat as you.  I injected liquid (29-94-90-.4zn-.1b) 5-6" deep with a "nitro" tool bar this fall.  It has trash whippers, followed by a coulter, then a shank with a knife similar to anhydrous, with covering disks.  They bring a nurse truck for me to fill from.  The product will settle out after a few hours.  I have to agitate the truck before filling the applicator, and I have to empty the applicator each night because it has no agitation. 

I had been dribble banding this product in the past.  But am concerned that most of the P is staying on top.  I have heard that P can only move down 1/4 - 1/2" per year in no till.  I am hoping that I have done more good than harm to my long term no-till soil by disturbing it.  The jury is still out.
