What’s above ground is a direct reflection of what’s below when it comes to crop development, but under excellent growing conditions you may not notice significant differences between plants with good root development and those with poor development. At the onset of drought or nutrient stress, for example, you’ll start to see a difference right away.
To demonstrate what’s going on below and to explain how tillage implement choice can hinder corn root development, Mark Van Veen, of Salford Machinery, takes us on a tour of corn root shape and mass under two spring tillage scenarios. Watch the video below to see which two implements are compared and see for yourself how to first evaluate compaction or density layers in the soil and the resulting root development of the crop.
