Angel, WVa is probably my favorite state in the US. TheMonongahelariver is so beautiful. Did you ever raft the upper Yough? Go to Dolly Sods? or Seneca Rocks? Allmajesticplaces. I spent 2 weeks camping and working with environmentalists out there. We took water measurements, built trails, fixed Mountain Lion refuge cages, and learned about coal mining and it's effects. I'd go back in a heartbeat.
Yeah, I've heard of places using ash mixed with salt. I couldn't see how ash would work. Cider is pretty much another form of graphite. And if you ever worked with it and gotten it on your hands, you'd notice that graphite is alubricant.
The problem with salt is that itdissociatesinto Sodium and Chlorine gas in water. Chlorine gas is toxic. In the presence of water, the 2 elements will not combine. So as long as there's water in the soil, you've got a toxic gas in there too. The gas will get absorbed by any living things, and will in essence kill it. What little water there is, has more salt in it that the cells of living things around it. The water from the cells is pulled out and the plant withers and dies.
Road ice is not NaCl, but it works on the same pinciple. It's still a salt, and still breaks apart in the same way

The salt runoff is a concern of mine, too, since we lived in the Allegheny mountains in WV, for several years. The amount of salt used in Morgantown in one winter.. sheesh. We actually ran out and the city was begging for supplies from several states away and no respite until the weather broke naturally. It was bad. But right in the valley there is the Monongahela River. Those poor fish.
The next winter, because we didn't know how bad it'd be the mix was mostly cinders with a little bit of salt. The number of black ice related wrecks rose significantly. Dangerous stuff. Lesson learned: cinders don't work any where near as well as salt.
Salt kills a lot of the nutrients in soil, doesn't it? I wonder how long it would take to naturally de-salinize(?) regions which had lands where too much salt had been used.
