In southern Ontario-near Detroit-our farms average 70-85 bpa depending on soil type, sandier soils usually lower, clays higher. No irrigation here. last year some 110+ crops,probably a once in a life time experience. Oh yeah,most went feed grade due to fusarium. Mostly soft reds_soft whites. Can't seem to make protein levels here to make had reds worth growing. Two years ago average was 40-50 bpa. Blah! Alot of times too hot during grain fill.
