Say a large forest fire took place. As I understand it, the smoke and ash would ride the wind and could be a health hazard even to people that are quite far away.
My question is will it damage the soil itself and its agriculture, in these places that are some distance away? If so, what will that look like (to what extent), and what distance are we talking about?
(This feels like a suspicious thing to ask, so let me just clarify that I'm asking this because this is a plot point in a book I'm writing, and I'd like to really understand what ramifications it would have outside of the specific place things are happening. I've asked related questions in other places, but I think this is the most accurate.)
Forgive me if the tags are inaccurate, I know nothing about any of this.
