Update from Southeastern Iowa

We’ve seen quite a bit of rain in southeastern Iowa. North of Highway 92 is wet but the crops are looking very good as we near the 4th of July holiday. As you move south of Highway 92 and closer to the Iowa/Missouri border, the more damaged and wet the fields become. One grower has seen 35 inches of rain in the last two months.
Extended forecasters have predicted the rain will decrease in the next couple months, leaving us with a hot and dry July and August – similar to the growing season of 1983. Early planted corn would be able to contain enough moisture to get through pollination but the extreme heat could hurt replanted crops.
In my area, 5% to 8% of corn has been replanted, but as we near July 1, it’s becoming too late replant corn and still expect a yield from it in the fall.
As you recover from the rains, I suggest getting into your fields and control the weeds as best as possible and side-dress nitrogen on the corn.
Even though there is some drowned out spots, there is still a potential for great yields in most areas.
