[Cob] wood & cob footings

[otherfish]

post bottom ends burried in earth is an option.
if you do, put a few inches of gravel in the bottom of the hole.
this is top prevent the post from standing in a water-filled hole when it
rains.  The gravel gives a drainage break from contact with damp earth
conditions.  This is important as wood will take up water into the cut end
grain & transport it up into the post - ergo internal & rapid dryrot of the
bottom of the post.

embedding a post in concrete where the bottom end of the post is totally
encased in concrete is a bad idea - if you must use concrete do the same as
above w/ earth - a gravel pocked below the end of the post & surrounding
concrete fill.  same reason applies.
