Legal Question in Real Estate Law in North Carolina

These are complicated questions. This raises primarily the law of "nuisance"; i.e. that the farmer is creating a nuisance that interferes with your use of your land. People are entitled to make reasonable use of their land, but there is a limit when they unreasonably interfere with their neighbors. You will have to consult with a lawyer (ideally in your local area) with a lot more specific facts to know whether this constitutes a nuisance, as there are many cases in North Carolina addressing what conduct constitutes a nuisance. Based on what you have described, it appears that you may have a valid claim.
