Biochar changes flow of water in soil

It isn't that it only holds more water and lets it drain better in heavy clay soil.  MOre water infiltrates, flows differently, and encourages more phosphorus development as well.

Interesting! Thanks for posting.

Phosphorus is the nutrient that many scientists tell you not to add too much of, or else, your soil won't create it by itself.  It makes sense that biochar could enhance the ability of the mycelium to deliver it through the soil when biochar is added.  Not just because it drains better and holds more moisture, but also because it can facilitate the connection underground of the mycelium to do that.  There are more electric flows underground with biochar, and that pathway is similar to nutrient cycling with phosphorus.
