I know of a man who digs a hole just bigger in diameter than a post hole about 2 feet deep right before season. He will then cover it with about 2 or 3 inches of dirt and leave it. He does this right in the middle of trails where he expects to see a buck. He tells me it works more times than not at stopping a deer at any point in the season early or late. I know some can not hunt over minerals, but it may not hurt your chances.
