Just from reading the article, I would assume the real value of the finding
was that it provides a high value crop for soils already damaged by salt
saturation, such as in the Sacramento Basin. Here's a location that's already been
so heavily irrigated it's worn out. A novel use like this, where the waters
available are on the saline side to begin with, could bring the region back to
life.
There would of course be other concerns. In the Sacramento fields I
understand selenium salts have built up to such high levels they are considered in
places to be poisonous. So high-antioxidant tomatos may not be a quick panacea
without some further work. But it's a great approach to bring damaged soils back
into productivity.
You're right, of course, to think that pouring salt on healthy fields is
probably not the best idea.
