Is it a bad idea to plant corn after sunflowers?

I'm wondering if it's a bad idea to plant corn after sunflowers because I been told that the sunflowers can grab all of the nutrients with their tap roots and the corn wouldn't have anything down deep. However, I think if a person banded fertilizer with an air seeder that wouldn't be an issue. The main reason why I want to do this is because I want to build up the soil structure and I believe planting corn after sunflowers can help build the organic matter faster. Any thoughts?

Where are you located? In South Dakota we follow flowers with spring. The tap root allows the wheat roots to access more of the profile and seems to be a good rotation. After spring wheat we will follow with winter wheat or corn. Wheat will add a lot of OM if that is your goal.
