FLOODED CROPS
The flash flooding in northeast Iowa has left many producers wondering what to do next. In many areas, the flooding of 2016 reached record levels.
Corn
Past experience has shown us that if flood waters got above ear height, the ears were likely ruined. That assessment was correct for the floods of 2008 and 1993, but corn was flooded near tassel stage. In those cases, ears under water were ruined, basically turning to mush within a week.
It is a different story this year. The August 24 flood occurred with most corn at early dent stage. In general, ears from these flooded fields still look to be in good condition, so far. The flood waters appeared to drop quickly, which in most cases will minimize potential problems. Here are some factors to watch.
