Hi,

Surely ACTIVE CHARCOAL is the best.

Combined with MAGNETITE added to the soil and POWDERED GRANITE in the COMPOST.

Ciao,

 Washing biochar to remove ash?

Paul,

to acidify biochar, you can use any acid (probably organic acids are the easiest to manage, but any acid would do and inorganic might be cheaper).

Once in the soil, the classical technique of adding sulfur, which bacteria will transform in sulfuric acid, would probably be the easiest thing to correct the pH.

I wonder what sort of pH biochar-mineral-organic display. Stephen?
