More on Char-Soil-Sequestration

In an earlier post we discussed the concept of making "char" out of agricultural waste, then tilling it into the soil. This sequesters carbon permanently.

This is not just about carbon sequestration, but soil quality and fertilization. The name in the soil geology field is Terra Preta, which refers to the dark quality of the earth where this method was practiced.

A company that is pushing this concept directly is EPRIDA. Very interesting stuff.

Here is another article on the subject and another and another great PPT from EPRIDA.
