There's a fellow over in "religion" maintaining
that small amounts (unspecified) of salt added to
soil works as a fertilizer for plants..   Any comments?

Is this likely?  For humans we know, for example,
that
A.some elements in small amounts are health-promoting,
though in large doses, toxic--e.g. selenium.

B. Other elements, like mercury, I gather are poisonous
at all levels, though possibly the effect is too
small to matter at the lowest doses.

Could salt, for plants (  or some plants) be like A.
category, in your opinion?  Any refs appreciated.

HW.

(For scientists:  yes I realize salt is not an element)
