Odd Question, probably for Ag/Chem people. What is the approx concentration of salt that is needed to render ground uninhabitable for plant life? I know this was a common practice in the ancient world, particularly with the Romans and lands they conquered. Long story short, I have at strip of land that, due to layout, placement, and my neighbor on the other side of the fence, is EXTREMELY a pain to deal with. I would like to just salt it to the point where it won't grow. I know there are chemicals that can do this, there are a lot of kids in our area, as well as pets, and I don't want to harm anyone, I just want this small strip of weeds/underbrush to stop being a pain in my buttocks. I'm just looking for a rough estimate, like "1 pound of non-iodized salt per square foot of land" or something of the sort, if anyone has any experience with it.
