Crop Summary

More ideal weather for growing corn in this area could not have been ordered. The crop came up growing and never slowed. Moisture conditions and lower than normal temperatures were nearly ideal all summer. We had an excellent corn year. This area was fallow the year before planting. It was disc, hipped, and do-all before planting.
