![](/profile/get-photo.asp?memberid=966&type=profile&rnd=980) Coldwater, Michigan | It's been a few years now, but in the mid 70s in NW Ohio it wasn't unusual to see readings in the 6-9 # P2O5/acre range. Saw some of those in the Flint, Michigan area 4-5 years ago. You can still raise 120-130 BPA in a reasonable year. In a good year as much as 160-170 BPA. So even with the low readings, "P" may not be your most limiting factor.
