Plant height varies drastically in many cornfields in Minnesota. This has been the case for the past six weeks and is especially noticeable in fields where corn follows corn even though corn following soybean is also extremely variable in height. In some fields the plants are taller in the tractor tracks and tassels are coming out from those plants but not yet visible from other plants. This makes an interesting picture in many cornfields.
