Dr. *************** and *********** and discussion of wasted inputs.

I've watched several YouTube presentations from these two and essentially say we spend way too much on inputs. Berns relates it to the welfare system for crops. We put on nitrogen and plants quit producing it naturally. I'm considering going to 60 or 75 in twin rows with low growing perennials for cover in between and using no inputs other than corn seed. Thoughts? Opinions on the two named presenters? I know yields may be lower but profit per acre should increase if they are correct.
