Yes, right, that claim is that made in a video by Dr. Elaine Ingham, called The Roots of Your Profits, which I mentioned in this same thread, here: https://news.ycombinator.com/item?id=26718277 and which links to a comment by me (in a previous HN thread on no-till) about her work and revolutionary conclusions. And her company, Soil Food Web, is set up to consult on implementing the findings of her work. And some major reasons both the number and diversity of microorganisms such as bacteria and fungi (and also other organisms such as archea, nematodes, arthropods) are low, is because tilling fields, not keeping the soil covered at all times as happens in nature (see Gabe Brown [1] videos where he keeps stressing how key this is and why), use of tractors, synthetic fertilizers, pesticides and fungicides depletes the soil of parameters needed for survival by those creatures, such as right moisture and temperature ranges, and organic matter levels. Not to mention the soil erosion and water body eutrophication
( https://en.m.wikipedia.org/wiki/Eutrophication ) and desertification that occurs over the years due to all these wrong practices. All in all, it's a deadly cocktail, and the exact opposite of how nature works. [1] Google Gabe Brown videos. He has videos, charts, stats, etc. for almost all claims he makes, claims about his neighbors' poor results compared to his, and about his performance vs. state and US averages. He has a standing invitation for any one to visit his ranch and roam around and verify his claims. |
