I have 40 yards of chalice soil. I need it removed and it is good for pads, retaining walls, potholes, road base, etc. It is not gardening soil. You will need a pick and a strong back. I can't help or deliver.
Caliche is a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt.
