Re: "macro life form" and "trees communicate", Gabe Brown and/or Elaine Ingham also talk about that. IIRC, Brown (regenerative farmer for ~20 years), quotes Ingham (soil biology scientist - soilfoodweb.com). So do some other regen ag people whose videos I've been watching, e.g. Richard Perkins of Ridgedale Permaculture, Sweden. Recommend his and Brown's YouTube videos for good overviews and even good solid technical details of what regen ag techniques are, and why they work (well, and cheaper than "conventional" ag). Both are regen ag farmers who have been doing it successfully for years.
