Be gentle with an existing forest. If your trees are already in place, then you may put the biochar directly in place around the trunks of the trees you want to help grow. You may rake the soil to put the biochar beneath the normal humus forest ground, to avoid it to be washed away to quickly. Depending on how you created your biochar (it may contain more ...

The answer is: Unknown. So try it. We need more data points. In general if energy can be extracted from a reaction, some bacteria does it for a living. Given the nature of certain ecozones, notably various pines that have a strong firesuccession (Lodgepole, Jackpine) then a series of low temmperature burns should leave substantial carbon in the soil. ...

There are many problems with the article you cited, but I agree with the main point it makes about the need for extensive research before any global scale solution should be attempted. Nevertheless, extensive field trials are not required to definitively prove the effectiveness of biochar to sequester carbon. Simply dig a hole in poor soil one foot wide and ...

There is certainly one way how to do carbon sequestration with biochar: fill empty coal open pit mines with that charcoal, and cover with soil. That's how the fossil fuel in that pit was stored for a very long time before humans thought it's a good idea to dig it up and burn it. When wanting to give biochar simultaneously tasks for soil amendment, it ...
