The (super)porous nature of the char is really amazing. one gram of biochar is equal to 300-400 cubic meters of surface area, equal to the surface area of a basketball court. Weakly negative charge too, which helps to hold onto (but still make bio-available) nutrients.

Good point bobrown14. Plus, as much as 10% of the carbon found in the Plains of US from 10,000 years+ of prairie fires. Rumor has it there's pretty good soil in the mid west!

More than just affecting yield (which I've seen a trial w/ biochar showing a 17% increase in dry weight), because the biochar retains more nutrients in the root zone (that would normally leach through the soil profile), there is a potential savings in fertilizer cost. The increase in water...
