Subject: Gypsum is the classic cure for high sodium soils.

Little River, TX

Dave,
Gypsum is Calcium Sulfate. The deal is the calcium replaces the sodium on the clay. Then the sodium becomes a fairly soluble molecule and can be leached out of the root zone.

Remember the sodium must have a route to depart the root zone for this to work. It is also possible for the sodium to ride along a clay or rock shelf and emerge later in a seep.
