You are absolutely correct, this has been known for a long time. The problem has been in funding more research and creating practical application of such findings through Biomimicry. Industrial Science for profit rules. There is no money in halting sales of various synthetic fertilizers and the pesticides that go along with them. These finding could also be used to dramatically change the face of Industrial Agriculture, but that will never happen because of this obsession with corporate greed through obscene profit making. If farmers and foresters actually knew how nature really worked and all that is necessary to keep the system healthy, intact and sustainable by changing practices, Industrial Ag would be mostly nonexistent. But hat's not how the world works and it doesn't matter which ideology is in power either.
