LMAO okay, you can choose to stick to the primary scientific publications then if you like instead.

I've got no stake in the matter one way or the other, but I do feel it's an interesting area of discussion. Perhaps the 18th century notion of organic material decay isn't the end of it.
Em-1 is great stuff. They use it for a number of different applications including for the smell of sewage.
You can use NAOH or hydrogen peroxide to create humates from humin. It can also be done naturally through oxidation or microbial breakdown. Shale, compost and river sediment are all natural sources of humates without any extraction.
Now I'm confused. Isn't hydrogen peroxide used to oxidize the coal prior to humic acid extraction with either NAOH or KOH? For example: https://iopscience.iop.org/article/10.1088/1757-899X/162/1/012025/pdf
Yeah, I know that one. And you do realize that's not a critique of Lehmann and Kleber's 2015 article right? It's a perspective article that basically says Lehmann & Kleber's ideas aren't novel, and blame the lack of a more interdisciplinary approach to understanding the fate of soil organic matter that have at least partly held back the science between Waksman's 1936 paper up until a handful of recent papers - most notably that of Lehmann and Kleblers:Frontiers | The (Bio)Chemistry of Soil Humus and Humic Substances: Why Is the “New View” Still Considered Novel After More Than 80 Years?
Three years ago, a novel “soil continuum model” was proposed, in which soil organic matter was suggested to be of heterogeneous composition and to consist of...
In all the uproar that followed the publication of Lehmann and Kleber's (2015) article, little attention unfortunately seems to have been devoted to the chemical nature and dynamics of humic substances, making it likely that we are going to witness once again what Jenny (1961), writing about soil acidity, once referred to sarcastically as a “merry-go-round”: There is a good chance that another Science or Nature article will be published in about 2025, extolling anew Waksman's perpetually “emergent” perspective on soil humus. However, from a more optimistic perspective, the soil science community may yet decide to take up Lehmann and Kleber's research agenda and, critically, note that the tools needed to answer their call and improve our understanding of the dynamics of soil organic matter at the microscale already exist, indeed have been available for a decade, but have remained largely unused.
