If only we always had the perfect conditions to plant corn each spring. Many think that cool soil conditions are a major risk factor (soil temperatures below 50 degrees F.) when planting corn. Of course, another factor to consider is planting into a favorable seedbed - No need to "mud it in" and cause field compaction to occur. However, the biggest risk factor to corn emergence is planting into soils that are near 50 degrees F. and then having prolonged wet soil conditions, because most replanting of corn occurs when seeds or seedlings are deprived of oxygen. In reality, if you are going to plant early, planting corn into cooler soils when seeds are less likely to germinate, then have wet conditions, is perhaps a better scenario. But, it will take around 110 to 120 Growing Degree Days (GDDs) for corn to fully emerge, so be cautious, because the longer that seed stays in the ground, the more likely it is for problems to occur, which could hinder the corn stand. Frost injury to the corn seedling after emergence is not usually a problem, but is something else to take into consideration when planting early.
If you are planting corn abnormally early, here are some suggested Burrus products:
