I've had great luck with a 10 dollar, 50lb. bag of salt, dig a hole, dump the bag, and mix the dirt from the hole with the salt in the hole.

easy effective, and long lasting, this has drawn deer in front of my cameras for the last few years, with only one bag 3 years ago.

and in some states, if you wait long enough after you put it there, you can hunt over it without it being considered a baited area.
