William, look at the video in the link that I posted earlier in this thread in regards to no-till/throw n mow. That video will explain more than we can in a post. Those farmers in that video have reduced their input by 70% in some cases simply by utilizing a diversity in cover crops. Those cover crops are simply rolled down into a mat of OM, which then feeds the critters in the soil, that in turn feed the plants. It's not as much the plants feeding the plants, it's more about the OM feeding the microbial populations who then feed the plants.
I agree. I've seen a significant change both visually as well as on soil tests in just a few years. My test plot is growing much, much better.
