chloride in soil question

[Patriotguy]

I do plan on getting the soil tested soon but I had a question about residual chlorides in the soil left from say someone that would use a sprinkler utilizing city water on their lawn , would it be safe to assume that the chloride absorbed from a previous year would be gone from ultra violet rays and vegetation having absorbed it?

Chlorine residues in tap water shouldn't affect plants in any way. The amounts are so small. However if you still want to avoid those residues, I have heard that chlorine residues from tap wather evaporates in a day if kept in open container. So it should evaporate from soil too.

Chlorine used in watering tobacco can result in beautiful leaves that will not burn. That's why low-chlorine fertilizer is recommended for growing tobacco. One FTT forum member who produced quite a lot of fire-proof tobacco in one growing season remedied the problem by not using chlorinated water during subsequent grows.

Exposed, chlorinated tap water does allow the evaporation of chlorine gas. That's what you smell, when you smell chlorinated water. However, when chlorinated water is used for watering a garden, the chlorine contained in that water becomes chemically bound to soil as chloride. The chloride does not evaporate. Instead, it is eventually consumed by soil microbes and any plants there.

That being said, residual chloride from watering during the 2019 growing season should not present an issue during the 2020 growing season.

It is true that chlorine evaporates, but some jurisdictions, like mine also use chloramine which does not.
