Toward Ecosophy

A permaculture demi-god, Sepp Holzer, has a technique of mounding up otherwise waste wood (like windfalls) into long piles, up to six feet tall. He then adds whatever manure he can get all over the pile along with other random organic matter, and tries to keep it from drying out too much. The wood breaks down over a period of several years, generating a gentle heat and turning into a long, fertile mound great for growing things. Carbon sequestered into new soil.

"Hugelkultur" is what he calls it. Plenty of videos online about it. (This is all from memory-- my German stinks.)
