Once your wall is dry, and assuming it stays that way, there should 
be very little biological activity (rot).

Robert Laporte tells of cutting open a 600+ year old straw-clay wall 
in Europe (I believe they were making a new doorway or window) and 
finding that once the clay was removed, the straw looked pretty much 
as fresh as if it had just come from the field.  The clay had 
essentially 'entombed' the straw and preserved it.
