I know the weather hasn’t seemed like it recently, but corn planting time will soon be upon us. Late winter/early spring always is a good time to do inspection, maintenance and adjustment of planting equipment, whether you are using the same planter you parked in the shed last spring, a “new to you” planter or even a brand new planter straight from the factory.
The main results of poor planter maintenance are poor seed spacing and non-uniform emergence. Uneven plant spacing can cause corn yield loss of 2.5 bushels per acre for each inch of deviation from the proper spacing. Deviations can be the result of plants being too close because an extra seed is dropped, or too far as the result of skips, or a seed that doesn’t germinate.
