I have to disagree with that. Salt will not remain in the ground very long. Every rain will wash more and more if it away until it is completely gone. It is typically considered that salt in the ground is 100% strength, after the first rain it is then considered to be 50% strength, after the 2nd rain it is 25% strength, after the 3rd rain it is 12.5% after the 4th rain 6.25%, after the 5th rain 3.1%, after 6th rain 1.5%, 7th rain .78%, 8th rain .4%, 9th rain .2%, 10th rain .1%. The salt is 99.9% gone after 10 rains, with evening showers in the summer the salt will be gone in a few weeks in TN where I live now and in Illinois where I use to live.
I know for a fact from experience that salt will kill the plant that you put it on and 30 days later new grass is coming up in the dead spot and in another month you can not find the dead spot.
One more interesting note, I don't remember the chemistry term for this but we learned this in chemistry class in high school. If you put 1/2 inch of salt in a glass then carefully fill the glass with water the crystal salt remains in the bottom of the glass. After 24 hours the crystal salt disolves into the water without stiring. The high concertration of salt in 1 spots tries to become more neutral so it spreads itself through out the entire container of water. Now you pour that glass of water into a larger container and dump in an equal volume of ice. When the ice melts you can see the seperation between the pure water and the salt water but tomorrow it will all be 1 mixture again the salt tries to become less concentrated in 1 spot and spreads it self through out the entire container of water. Salt does the same thing in the ground. You pour a cup of salt on the ground and in 2 months you can not tell salt was ever there. Naturally this will not work if you pour salt on rock or in the desert where it never rains. Research shows that salts goes down very deep in the soil.
One more fact. In the north the highway department puts several tons of salt on the roads in the winter. If salt did not go away all by itself then there would be no plant live anywhere near any highway, road or street.
