Treating the Farm as an Ecosystem with Gabe Brown Part 1, The 5 Tenets of Soil Health

Gabe Brown mentioned it in this lecture on regenerative agriculture. Sorry, but I don't have a timestamp, it's been a few weeks since I watched it. this video I'm not an expert in farming, but I do know a little bit of plant biology. My understanding of what he said was that the combination of atmospheric CO2 and fertilizer increases the growth rate of the plant, but the plant doesn't uptake a proportionately larger amount of other micro nutrients, either because it is biologically rate limited or doesn't have access. Other Googling suggests that it could be a result of selective breeding picking crops that grow faster but are less nutritious, but that would seem to be a correlated problem. Those crops tend to be selected for their ability to grow with synthetic fertilizer and *-cides, with the lack of nutritional value being an unintended consequence.

> So who are you planning to put to work as agricultural stoop-labor peasants? Are you volunteering? I mean, we used to harvest all our crops that way. The people who did it were generally...not volunteers. I find it strange how we have cell phones and solar power and other these other wonders, and yet arguments always goes straight to slavery anytime the specter of higher labor costs comes up. One would think innovation, especially on this forum. The obvious, immediate way would be to fix the immigration laws and enforcement to allow in as much guest labor as needed. If the economics are an issue, then selective use of farm subsidies are appropriate given the positive value being added to the land in terms of increased productivity and soil quality. Eventually innovation will bring the costs down. > As far as higher yields go, I don't believe you. Another silly comparison to the past - agricultural science has advanced multiple times in the last 80 years. No one would argue that modern, chemistry-based farming isn't productive, simply that it's less productive (and far, FAR more detrimental to the soil) than what modern science around restorative agriculture can produce. Restorative Ag 101: this video For what it's worth, I also think Corn yields are probably impacted by how heavily subsidized it is. That's a policy that started with the New Deal in 1933, so it makes sense that the graphic would start to increase there.

Experiments on soil compaction show the rolling to be better, the roll needs not to be that heavy, only to kill the vegetable. Also, you don't do a separate pass on the ground, you just roll it at sow time, so no extra gas. Also, the vegetable cover absorbs CO2 and later fix it to the ground. Here is a thorough comparison of soils and methods this video

In this talk from 2017, around 1h30m in, he says that he hasn't yet found a way to make no-till organic work in terms of weed prevention. But, he said he was close to figuring it out. this video Has any progress been made since? Is this an area where technology could help (eg robotic precision weeding machines)? Disclaimer that I have yet to read your article so it may already be covered.

"One teaspoon of healthy soil contains more bacteria, fungi and other microbes than there are humans on Earth. Those hungry organisms can make soil a difficult place to store carbon over long periods of time." The natural respiration of soil microbes is small compared to how much carbon can be naturally sequestered in healthy soil due to sustainable agricultural practices. Healthy soil is well-known to hold substantial amounts of carbon, right along side such organisms. The development of unsustainable agricultural practices (monocultures, single-planting seasons, letting fields lie fallow, tilling, chemical sprays, essentially Monsanto's entire business model) has destroyed soil biodiversity and health. Healthy soil can absorb an inch of rain every few minutes. Fields flood (and crops are subsequently lost) because the ground is hard and crusty, preventing soil absorption. If more cropland soil had the healthy consistency of cottage cheese, flooding wouldn't be an issue. Yes, forced carbon sequestration might not work in the presence of healthy soil. However, fixing the deficient soils created across the world from unsustainable industrial agriculture practices will naturally sequester carbon. I would love to know exactly how much carbon no longer is trapped in our soils that once was due to the last 100+ years of unsustainable industrialized agriculture. this video link

I don't know what scams you are looking at but regenerative agriculture is incredibly complicated and time consuming but not physically labor intensive because it is compatible with mechanization. Conventional argiculture is the simple and lazy version where instead of trying to understand your local ecosystem you just douse everything in fertilizer, pesticide, etc so you don't have to care what is happening in your soil. this video
