There are lots of very clear definitions of what a sub soil is on the net some more technical than others. I have understood it to be the less biologically active layers under the immediate topsoil where all the really frisky biological action is taking place. yes I know biological action of various sorts can continue to some depth but the top soil is where it is at. So if archaeologists have been misusing the term where are we going wrong?
