Salt Damage Antidote?
I've got a few maintenance accounts that have experienced turf damage from road salt. Anyone have an antidote for the salt? I think I remember hearing something about gypsum, but I'm not sure.
With enough rainfall, the salt will clear, but I'd like to speed the process and score some points with the clients. Any suggestions?

I drove by a large commercial account this week where a contractor had taken a sod cutter and stripped 2' back from the curb. They topdressed with some topsoil and seed and in a few weeks you won't even know the difference. Labor intense but guaranteed success!

Granulated gypsum. Spread like lime.

Gypsum works for salt damage, but by the time you add enough to counter the chemicals from the sod, you are alomost as well off to fire up a Ryan and remove the sod, then relay. I have found it was one of those 6 of one, half dozen of another type of things, assuming I had the right quantities, which, we if I can remember something like 20 lbs per 100 sq ft. Now we add alot of gypsum to break up this disgusting clay we call soil.

I borrowed this from another site
Gypsum (calcium sulfate) aids to aleviate high concentrations of salt in soils
and is an excellent product for treating crusting soils. The problem with
gypsum is it is generally applied at the wrong time. Gypsum should be used
only when there is no lime and the calcium levels are below 2,500 parts per
million. 2.Gypsum400-600 pounds per acre
It's been claimed that adding gypsum can reduce compaction, improve soil
tilth, improve water infiltration, raise soil pH, lower soil pH, correct salt
problems and improve the calcium-to-magnesium ratio.
the only real benefit to applying gypsum, other than supplying sulfur if
needed, comes when it is applied to sodium-affected soils.
In cases where a sodium problem exists, gypsum, which is calcium sulfate,
supplies a soluble source of calcium that will displace some of the sodium.
The sodium can then be leached deeper into the soil profile as the soluble
salt sodium sulfate. If soils are sodium-affected, it often takes 1,500-3,000
lbs. of gypsum per acre to effectively remove enough sodium to improve soil
structure. "If soils are not sodium-affected, gypsum will not improve poor
soil structure.
