enlightened us thusly:
You could do it if you had a salt marsh that gets flooded by the tide
twice a day. There are crops that will grow in sea water, but not many.
Because the sea washes the land twice a day it stops salt from building
up to get any more concentrated than sea water.
be easy enough to have artificial tides, or surplus water supply so it
limits the salinity.
Hence, though the GM crops which thrive on salt. Now that would be a GOOD
use of GM technology, rather than the currently-typical "lets try to coner
the market to make lots of dosh" approach.
In gurbel you could engineer plants that would take salt out of the soil. There are biochemical pathways that some animals use to pump excess salt out of their system. If the plants extracted salt from the soil and stored it in their tissues you could harvest the crop and take the salt away. I can't see a way of making it profitable though.
