Corn rooting depth varies on soil conditions. Literature says that corn roots can go down over 8 feet. This is not typical. Many corn fields likely have rooting depths of less than 3 feet. If you have a tillage hard pan it might only be 10 inches.
There are a lot of weeds and likely the deepest rooting weed would be a perennial of some sort. I do not know the deepest rooting weed. My weed books do not list rooting depth. Thistles tend to have deep roots and are likely to be among the deepest.
