It has been my experience that if you hunt you need to give something back to the woods. Food plots and Habitat improvement can be expensive and very time consuming. One great thing that a person can do to improve your deer herd is putting in a salt lick. Deer are just like us in that the require salt to live. With that said deer will find salt somewhere somehow just like water. You can put in an inexpensive salt like for you deer without much effort at all. The way I put out a lick in my area is to get a bag of rock salt or drive way melt after the winter you can pick one up for very cheap. Take you salt out and find a good spot just off a trail. Prepare the ground with a rake or shovel loosening or turning over the ground in about a five foot area. Pour your salt on and mix up the salt and soil. There you have it but be prepared for the deer to dig up the ground around your salt lick. You can also add deer cocaine or rack builder to the ground as well and the deer will like you even more for it. Check with your local game warden or wildlife biologist to see if this is legal in your state. I wouldn't recommend hunting over your lick you will see that the deer will come to it to acquire salt but it should not be considered as bait in any way but a way to give something back to the deer and wildlife that you love to hunt and eat.
