And part of me is screaming for citations while the other part knows that an examination of the literature would reveal the same structures, just one level deeper---one or more warring camps that aren't even talking to each other any more.
So you have many different types of soils, and that will produce variations. You have different histories on those soils, you can measure for a dozen minerals, but what about those tiny trace minerals? Top soil optimization...nutrient run-off that creates fungal blooms in the ocean killing life in the ocean, price per pound to produce produce, shelf life of produce, how it looks, is the taste in fashion ----- so take those dimensions that you can measure things on --- and then multiply that by the number of different veggies and fruits and all their different types (eg. how many different apples are there??)
It's too massive problem space to solve with a few studies...and the financial incentives and ideological thinking further muddies the waters.

This doesn't mean it's necessarily wrong, just that it is not even remotely a scientific perspective on the situation. Its
"USDA citation" is to what amounts to a marketing-focused whitepaper.
Can you elaborate on this point?
Anyway here is a journal article by a Canadian govt scientist that refutes that minerals in food/soil is depleted:
I guess most people today eat much more than five times the amount commonly available to people in the bloody days of WWII.
Second, yes, by definition regenerative agriculture is scalable.
It might require as much as double the labor requirements (so 3% of the population rather than 1.5%) but it's likely that automation will amortize that.
See "How is China able to provide enough food to feed over 1B people?" https://news.ycombinator.com/item?id=20537409 which describes some aspects of China's agriculture that are regenerative.
Also, I recommend Toby Hemenway's "Redesigning Civilization with Permaculture" talk for background and future directions.
Geoff Lawton's "Greening the Desert" project converted salty desert to producing figs and other food in just two years.

Just to mention one (gross) example: It's a little-known fact that Eisenia fetida worms will devour "night soil" (#2's) and produce clean-smelling castings, while doubling in biomass in approximately 40-50 days. This could easily be scaled to handle urban sewage densities, returning that matter directly to the ecosystem without expensive treatment/chemicals etc.
I believe the booming population thirsty for beef, chicken and similar massive products is driving the agriculture of corn, soybean and wheat to its limits.
So growing food in your backyard, assuming you don't spray it or have heavy metals in your soil that are ingested by the crop, are likely fine.
How alive is your backyard's soil? A lab would have to analyze it. It may or may not have the right minerals, depending on what you're trying to grow.
I brought in a lot of compost to "start" it, so who knows what is in there. Furthermore my home is recently purchased, and the previous owners did the land no benefits (unkept dogs in the lawn, terrible looking dirt, etc). However I'm working towards / practicing no dig, heavy mulching of both green and brown (both in beds and out of beds) to promote natural breakdown and soil improvements, and tumbler composting (to combat rodents).
I plan to soil test in a few years, once I've become more established. Right now I'm primarily concerned with establishing whatever is sustainable for me, and then measuring what I might need to tweak. We'll see how it goes, hah - I'm pretty new to all of this; and I have more yard than I (an indoor man) knows how to deal with :D
If this is known to be the case, how does this pass food safety?
It amuses me somewhat, because most of the people here are either on wells or the water coop, and AFAIK the latter only chlorinates. But, education never stopped a good conspiracy from roping in true believers...
Yes, they did inspect the chicken, feed, etc.
Total cost to purchase is $20/lb. majority of the cost coming from feed.
Regardless if you can pick apart my story or how honest the entire process is, I’m not sure this is sustainable. Who can afford such prices?
If this is the case (and true at face value), what are our choices?
I don’t want to be a Debby Downer, just passing along info.
We could be creating less waste, or healthier food products, the question is how do we systematically explore new spaces like that, even when there isn't immediate payoff. We shouldn't just rely on lucky whims of individuals - if nothing else our overall system conspires to a smaller ration of fewer individuals financially capable of indulging such exploration.
Not sure about $20/lb - I guess this means most don't eat chicken often - but...
It may well be that we just have to spend more on food and less on rent (for example). In aggregate it wouldn't be much of an issue if over a period of 10-20 years food prices increased and something else (due to limited individual budgets) decreased.
