What is the usual treatment for hard clay soil, should soil this bad be
dug
up and replaced?

Are you sure it's clay? The dirt looks salt affected to me but it's a bit
hard to really know without being able to see anything of the soil
structure.


Yea its clay alright, and it's heavy, it smears and sticks to shoes after
the rain.
