If it's a 14/4, you could try putting XLR ends on it, then adapt it back to un-balanced with an XLR to 1/4" adapter. I don't know how well it would work in terms of noise, and it would also require 3 conductors to get only 1 channel of audio, but it's an idea.
With a Cat5/6 this would be easy work for any passive balun, I think. I've used the Liberty AVO-A4 for that.
Line audio needs to be shielded or at the least, twisted pair. Speaker cable has no way to reject noise. That said, the soil should limit this, but if it's run parallel to powerlines, nothing is off the table. XLR isn't made or used for high power and the losses post amplification over long distance makes this a tricky problem.
