NW Ohio | Although there were a few years that were very wet, it has much more to do with temperatures (nighttime) during grain fill (July) for corn. Sometimes, this is also associated with dry conditions. However, going through the data, the years that have over 12 inches of rain in April and May combined have had significant impacts on the national yield. That 12 inches is based on the corn belt region from the NOAA website. 1983 and 1995 were two years. In 1993, the precipitation came in June (over 12 inches) which caused significant yield reductions. | |
