Jerry,
I seem to remember from five-six years ago that this was researched in MI
by now retired, Dr. Jim Flores. The results were not positive. What was
recomended from their research was a small amount of CA applied by overhead
irrigation on a daily or semi daily timeing. I may well not have this correct.
I'm sure Mi. State can give you a more complete answer.
