[Terrapreta] The Science of Terra Preta Formation

[Greg and April]

Good question.

I'm inclined to think that the semi-porous nature of the pottery, means that the shards would retain air, when the soil is water logged.

  To All,

  As I follow the discussion, it seems mostly about chemistry,

  How about structure? Heavy rains leach and compact soils. 
  How might pottery shards change this?

  Just wondering...
