| Problem is this...hard to calibrate machine to push or pull product as with a boom in hills. Airflows work fine in the flat ground but with the new spinners will be more consistent over a long period of time in a wider range of environments. This comes from personal experience and also talking with people at the factory. also much harder to keep a boom in this range and it good operating shape for the long haul after many acres, which is the reason why most are junk or trading after a year or two.
attached link on Urea and volitilation...with conditions like last week can pay in as little as two days. Three bucks an acre cost doesn't take much to save or you cannot buy much extra for that.

most do not understand what a morning dew and heat can do....it doesn't melt into the ground it melts into the air and is gone. June is a terrible month to put untreated urea on the ground.
