This URL sort of suggests watering a lot and gypsum to dilute the
salt.

"The best thing to do if you are facing this situation is to pass
large quantities of water through the soil, trying to leach the
mineral salts out of the root zone. This can be enhanced by the
application of powdered gypsum.
Gypsum binds with salt ions and helps to carry them through the soil.
Apply at least 10 pounds per 100 square feet, and water, water,
water. If the water starts to run off, stop and let it soak in for a
while. Then repeat for as long of an interval as possible without
run-off. Cycle through many times and hope for the best. To avoid
some of this danger, and fertilize more effectively, read this
article"

As I recall, the Dutch use gypsum to repair fields that are damaged
with salt when a sea dike fails.

Yes it is a remedy for sodisation, the calcium displaces bound sodium and
allows the sodium to be washed away.
