Yes indeed, Jack. I would be very curious to hear your thoughts on this. You can Google "no-till method." Many guys doing it with wild success.
In a nutshell, the soil is more matured in terms of delicate texture and bacterial / fungal networks. This system is completely disrupted when we dump the soil. Much of the fungal network needs to be rebuilt. Colonies of cooperative bacteria have been spread all over the soil and they have to "re-group". Specifically, endomyco fungus won't even start growing again until live roots (exudate) are present.
When you first chop the plant, however, this fungal network will remain in-tact and alive for a few days. If you plop a new seedling in the soil without disturbing the soil, the fungal network will immediately shift its focus to these new roots. The seedling doesn't have to wait to start receiving the benefits of being plugged in to the organized microbial system.
Also, the nutrients are tucked away by the microbes, for when the plant needs it. The microbially stored food is right next to the microbial delivery system. All in tact.
Simply feeding the plant with a bit of top dressed compost and EWC is sufficient to keep necessary nutrients available. Shockingly cheap and efficient.
