Burnt soil is made by heaping a mound of moist (but not wet) clay-rich
subsoil over a a wood fire. We do it here by digging a shallow pit (1m x 1m
x 25 cm deep) filling it with wood (large branches, 4 x 4 off-cuts, &c) that
is then set alight and allowing it to burn slowly for an hour (much as yu
would set a BBQ) then carefully mounding the soil over the smouldering wood.
The whole is allowed to burn for 2 - 3 days at the end of which the now
semi-baked is removed and broken up. The final product is granular/small
lump (1 - 2 cm) size. What it adds to the mix is a rich source of phosphates
and microelements, some good structure (since the granular parts are quite
hard) and also a source of silica.
