More information about hugelkultur, which uses available carbon rich plant matter as the basis for a raised bed.
Building a hugel is one way to practice carbon sequestration on a small scale. The carbon they this tree ate up from the atmosphere will be captured in the soil and used to grow more plants that will then consume more carbon from the atmosphere.
Imagine doing this on a massive scale, burying carbon rich matter in our agricultural fields to regenerate the soil's carbon supply and prevent the release of more C02
basically if we don't do something to replenish the carbon content of our arable land, sooner or later the soil will die and become merely dirt — like you'd find on the moon or Mars. We could kill two birds with one stone here, taking carbon from the atmosphere where there's too much of it, and putting it in the soil where there's not enough. Anyway that's my amateur ecology lesson for the day.
@checkervest yeah I think so. Honestly we need as many trees as we can get right now, but this is a good way to deal with wood waste.
@interneteh Is this similar to the stuff that's being done in (IIRC) Brazil with burying biochar made from sugar cane processing waste?
Though, they're using biochar, rather than just burying the sugarcane waste... and I'm not sure how different in composition/pH/etc sugarcane waste is to wood.
@dartigen biochar is its own thing, but it's the same idea. You're burying a rich source of carbon for plants to draw upon. And biochar, like these logs, increases moisture retention. I plan to include some biochar or charcoal in this bed.
Biochar is a bit different, best added with plant matter to your compost heap, where it'll soak up nutrients & act as a home to microorganisms
A lot of soil carbon is living microorganisms. Bacteria & fungi get food (carbon) from dead plant matter, also from the sugars that plants make from the sun, some of which they exude from their roots
Bacteria & fungi both make sticky (carbon) stuff that sticks soil together, giving it good structure, letting in air, roots & water
the paul wheaton image source beings me to mwntion that I listen to his podcast, good stuff, though I wish they had slightly better sounding audio recording eauipment.

It's generally advisable to keep hugelkultur beds a termite-safe distance from your wooden structure home. In my head that's a forgetfully blurry 50-150 feet, no idea anymore which estimate i was given.
@brettleeper thanks. I don't have that kind of distance. But this is as far from anyone's house as I can get it, and it's on the side where there's concrete slab.
