Years like this, when corn-planting progress is ahead of normal and we get really optimistic about it, frost raises its ugly head. In the NW corner of Iowa, about a third of the years will include a frost in May. About ten percent of the time it is after May 10. Watching the recovery of emerged...

Planting occurred at a near record pace in much of Iowa due to lack of rain in late April. This string of dry weather also allowed most herbicide applications to be made in a timely fashion, but now there is concern about herbicide performance after prolonged time on the soil surface.

Farmers in Iowa have been experimenting with very early soybean planting dates, from late March to mid-April.
