Ovo se čini kao dobar dodatak kompostu/humusu
Posebno kada imamo organski materijal pun sjemena ili bolesti koji bi inače bacili

Drugačiji pogledi na biochar
Jedan od problema je što diže pH zemlje isto kao i običan pepeo
Znači s njime treba umjereno

[Drug Mile]

Kod mene je PH i ovako visok, sigurno neću pokušavati s ničim "spaljenim" u vrtu, bilo ugljen, pepeo i sl.

When a tree dies or is cut down, the carbon stored in the trunks, branches and leaves is released; but when plants and trees are "only" reduced to charcoal, the carbon remains in the charcoal, apparently for periods up to 50,000 years, according to research by Makoto Ogawa. And this explains the high levels of carbon in Terra Preta.
