I am aware of one report of nails being used as an attachment point buried 
in cob and there being nothing left of the nails in the cob after one 
year.   I don't know any specifics about this, but it is important to keep 
in mind that some soils are much more acidic than others which could have 
significant impact on your choice.

FWIW.
