Salt (sodium) messes with the ability of plants to absorb certain nutrients from the soil, so if that soil wasn’t very rich to begin with it can easily starve whatever is nearby.
I personally tried to kill weeds with salt in certain spots of my backyard and failed because it has plenty of nutrients and good drainage, salt doesn’t last long after a couple rains.
Sorry, I still don’t get the part about “salting the earth”. Is that something people do to get rid of weeds?
Yes.
And it’s just as bad / good as glyphosate?
No, salt is not toxic. But makes it hard for most things to grow until the sodium washes up.
The handy men did manage to kill one of our roses by salting our sidewalk against weeds.
