Could worms bring it up?

That's' what I was thinking. I've found worms at the top of mine already, and it was just created last fall.

These are some major ones, I'm sure there's plenty of other processes going on that we haven't observed or don't understand.
A great read if you're interested in these kinds of things is Teeming With Microbes by Jeff Lowenfels and Wayne Lewis.
thanks for the input yall, i have read teeming with microbes and recommend it often. the issue for me though stems from an urban position. im a part of a small band of city farmers that help communities get spaces up and running. we urge (as best stout egalitarians can) people to design collective beds over individual plots and building soil. the trouble is, brooklyn is one big brownfield, whose patchwork is less distinguished by clean and unsafe growing conditions and more a question of what myriad contaminants can be found. soil remediation has been a key activity for us, and hugelkultur beds are ideal structures for mycoremediation. this is a little tangential but i'd love to speak with yall more about it.
often there is no soil where we work and we are vehemently opposed to acquiring soil from somewhere else. if it actually is any good, it has been taken at the expense of another location. we have no interest in perpetuating the process of funneling resources to cities. this leaves us with a predicament. hugelkultur beds with sheet composting on top produces a lot of organic matter. our projects have worked well thus far but my nominal research into soil sciences tells me we are missing key components to long-term system stability. we have access to rock powders from stone masons here in brooklyn and are always eager to break up the concreted below (not asphalt) to push the way toward new parent material. what i was wondering, is where would mineral matter go in a bed with little or no soil? below the logs to be taken up by life? between the 20" sheet compost layers and the logs? some combination of the two?
perhaps another tangential thought id love for us to discuss is how to create soil.

i have sent people to wheaton's site on hugelkultur many times and will continue to do so. thanks so much for the contributions. but i'm still left with a growing issue for me. how does mineral matter in subsoils make its way into the upper regions of a hugelkultur bed? organic-rich topsoils contain around 6 percent organic matter. one thing i've learned over the years is the importance of mineral components -- compost isn't a cure-all by any stretch. nutrient cycling will depend on access to the soil parent material.
yes, i know that taproots and other deep-rooted perennials will access spaces under logs, but how much is enough? how many years until they do so? which ones are efficient at doing so? there is very little discussion around the need for mineral matter in raised beds of 5 or 6 feet tall..
as someone who makes soil where there isn't i run up against the difficulty of balancing composition. sheet composting and hugelkultur have been frequent approaches, but this is a lot of organic matter to place upon dense material like wood. im happy with everything ive made thus far but i'm always seeking ways to improve upon my gardening.
