Out in the field, you may get confused about uneven spacings. After the corn emerges, there are simple ways to determine the causes of problematic plant spacings. Farm Journal Associate Field Agronomist Missy Bauer gives you’re the guidelines in Episode 3 of Corn College TV.  

“A double occurs when the planter meter picked up two seeds and dropped two at the same time. In the field, it looks like you have good uniform spacing on either side of the two plants that are too close,” she says.

On the other hand, a misplaced seed looks different.

“Although the spacing is still real close together, there’s a gap from where the seed should have been on one side of the grouping. In this case the meter functioned properly in releasing one seed at a time, but there was ricochet in the seedtube, which cause the seed to bounce and the timing to be off,” she explains.
