Is there much evidence for nitrate conc being a definite indicator of cattle having inhabited a surface?
If so, how far back in time would it be reliable? I'm inclined to think that any increase would probably have long since washed away.

I'm quite interested in this idea, as it has bearing on a site up here that's a bit of an anomaly.
