The yields here is central Wisconsin are crazy good for what we had for water this summer . Irrigated yields are record high .  I have some dryland fields that I would have sold for 50-100 bushel corn in Aug and Sept. Went 95-190 . Have know idea where it came from. Cobs did not look at good. Looked like hell for months at a time.  6 weeks with about 1 inch of rain. This is on Sandy soils.
