Well, it seems that dumping huge amounts of salts onto the beds would raise the electrical conductivity of the soil, but that is like saying watering the garden would raise the electrical conductivity of the soil (if I am understanding this correctly). So it seems that raising the electrical conductivity of the soil can actually be a good thing or a bad thing.
However adding a huge amounts of salts is still not a good thing because it seems to kill off the biological organisms that live in the soil. I just learned that is called soil-salinity.
