I-75 Day 2

In our first ever Ohio Crop Tour, we split up into two groups of farmers, agronomists and farm journalists and toured the state to get a handle on what kinds of crop yields were out there. One group handled the western part of the state traveling the I-75 corridor and the other went down I-71. Overall, both groups saw quite a bit of variability, but yields averaged 139 bushels for corn and 59 bushels for soybeans. The I-71 group averaged 144 bushels for corn and the I-75 group had 134 bushels. In terms of soybean averages, the I-71 group had 59.5 bushels and the I-75 group averaged 58.75. In general, both groups felt they had a fairly accurate handle on corn, but thought the soybean formula was maybe 10% to 15% too high. Here are some of the County results.
