Dear Frank You are a genius.
Thanks for providing an interesting mechanical explanation for a reason char may increase production. Char holds a huge amount of moisture. So will a sponge but it is mechanically weak. Char is not. So the char can hold water and reduce shrinkage be feeding that water into the surrounding soil preventing the breakage of micro roots and promoting growth. There are other things that may also do this - like porous clay and possibly some types of garbage.
