I have read several recipes over the years but can't find them now that I need one. Any ideas?

We buy ours from the feed store. We use the mineral block with the sorgum binder. There is salt, cracked corn and some seed mixed with it. All critters love these blocks. The birds rabbits deer etc all really give them a working over. Rain is hard on them as they are soft. The animals do not like the hard blocks. Not sure what the binder is on the hard block but you can feel the difference.
The turkeys will come to the soft blocks every day. They will not give the hard block a second look.

Think the softer blocks would be the best remedy, anyway. As they dissolve, the salts/minerals leach into the soil, making a true "salt lick".

Have hunted on ranches that had salt blocks set in certain places for years, only to have to remove them by forest service/BLM requests. The game animals still come to the old places to eat the soil, which has become a natural salt lick.

Here is the recipe I use, they really dig up the ground to get at it.

WHITETAIL DEER HOMEMADE MINERAL MIX RECIPE
Ingredients: Makes 200 lbs. for about $23.00
1 part Di-calcium phosphate, this is a dairy feed additive bought at feed stores.
Comes in 50lb Bags at around $11.00 you need one bag.
2 parts Trace mineral salt, the red and loose kind without the medications.
Comes in 50lb Bags at around $5.00 you need two bags.
1 part Stock salt, ice cream salt.
Comes in 50lb Bags at around $2.00 you need one bag.
Directions:
-Use a 3 pound or similar size coffee can to use as your measure for each part of the mix.
-Mix all together well but not until ready to use, keep ingredients separate until ready to put to use.
-Dig or tear up a circle in the soil about 36 inches wide and about 6 inches deep.
-Mix your mineral mixture with the soil.
Maintenance:
-Replenish in 6 months with fresh supply of mineral, and then each year there after.

I used to mix the trace mineral with white stock salt. Now i just use the trace mineral blocks. I think digging up the area and salting initially is a good idea. Putting the lick in and area that is clay soil helps also but I have seen some of the most impressive licks beside large tree roots in hardwood bottoms.

Using licks to manipulate deer travel routes is very effective.

If you have old forest cuttings ie stumps, hollow logs, just pour a 20# bag of rocksalt into it. About this time the the year. You'll have a hole about 3ft in dia and 1ft into the ground by this fall.

I just put it in a 5 gal bucket add water desolve in the salt throw the lid on it throw it on the 4 weeler
take it to your spot work the dirt alittle so to pond it day or two all gone soked in . as you know they like it best after its in the soil mdel747
