Good arable soil makes lousy bricks. you want dead dirt and clay and straw.
We got plenty of dead dirt around here. Live soil is what is scarce
in plenty of places.
No one is going to do this anyway. Cheap shakers for concrete block
are everywhere and
block is what everyone wants to use. Using bad sand or not enough
concrete produces blocks which dissolve in a few years tho.
