So there is probably an agronomic strategy as well as a marketing strategy that comes with early planting. Especially on well-drained soils, that's the key now. If you're going to take advantage of the September new crop month for selling corn, you are going to have to get your crop planted early. Of course, now that it's May 1, that's not going to happen this year.
Sometimes it pays huge dividends to wait another day or so before planting
One of the considerations about planting in soils that are too wet is the possibility of sidewall compaction and other problems developing, says ISU's Elmore. Roots from the plant never leave the channel or trench the corn seed was planted in. That can become a bigger problem when you start are using starter fertilizer and those roots can't branch out to actually take advantage of the fertilizer to get the crop off on the right foot.
It's going to be cool temperatures possible mixing with sleet and snow later this week in Iowa. What can happen to that seed already in the ground if it absorbs that cold moisture?
One of the things that happens is as soon as the seed is planted it starts absorbing water. So, if that water is cold it can start to damage the tissue of the seedling and it can cause what is called imbitional chilling. Some of the symptoms of that are that you get the seed starting to swell and it doesn't germinate or you can absent or fragile primary roots as well. It just doesn't allow the seed to start out the way it needs to.
