Well, nature typically gets you LOS/permaculture but NOT high brix (with some exceptions).
Doc has truly put the science in the soil; so you get the ideal ratios of nutrients & necessary microbial activity that certainly exist in SOME places in nature, but that's purely by chance/luck. If you want the "recipe", you need the kit!
Wild apples rarely taste as good as apples cultivated by someone who knows what they're doing and has good soil.
Wild roses rarely bloom as often or as large and vibrant as their cultivated cousins.....
Etc.
When we talk about nature, I'm always amused that we seem to presume that human beings are not part of nature, or against nature, or stand in the way of nature.....or something like that.
In actuality, human beings are cultivators. Barring other factors, we are the only species that can purposely improve soil on a large scale. We are the only species that can till the earth and plant crops, irrigate, etc. We would all have starved to death many thousands of years ago if we did not NATURALLY posses this ability.
When I think of High Brix gardening I think of a symbiotic relationship between soil and human being. Just like plants need soil minerals and microbes to thrive, soil needs human input in order to have robust microbial action. It's natural!
Now, there are indeed some places on this earth with naturally occurring, mineralized, living soil. And these places often feature traditional farming methods developed over thousands of years that take advantage of the rich, fertile soil. I'm talking the Nile Valley, Volcanic soils around Tuscany, volcanic soil in Hawaii and other places known for exceptional quality of crops.
Here's where people go wrong: they copy the traditional methods, like KNF......Korean Natural Farming.....but they use soil from a bag, bought in Texas, or California. It's not the method of farming.....ITS THE DAMN SOIL!
If you happen to have good Korean soil and the various things they use to cultivate and fertilize that's all well and good! But to use Brand X potting soil, or backyard soil from Mendo and then pretend to be a KNF farmer is quite silly, IMO.
Copy the soil first, THEN copy the methods. This has all been studied, tested, quantified and re-tested. What we have with High Brix soil is the most active microbiology possible, given our current knowledge.
Therefore, I advise against "LOS" methods, or KNF methods, etc. Sure, someone is going to use the and do great work with LOS or KNF. Others will suck at it, and many will be in between. It's not the method.....it's the soil.
Start with the good stuff, understand how to keep it happy via foliar feeding and drenches and it's pretty damn easy!
Complicate it by fitting the round High Brix peg into the LOS square hole and your results will be inconsistent.
