The future of agriculture is in their hands?

These are the smartest farmers in the Central West of NSW, searching for salt. This is our CMA Farming Systems class on a day trip to various sites around Wellington where salt is a problem. We learned the difference between salt load, salt concentration and salinity.
We learned that our area (Goolma distirct) is a salt problem area, so we'd better watch out for the telltale signs. Such as sea barley (pictured), a species that colonises saline land. I wonder when Christ said "Ye are the salt of the earth" if he knew that one day it wouldn't be such a good thing to be... More about salt later.
