Over winter break I made two new licks with 100 pounds of salt in each...the salt is all but washed into the soil and with spring break coming up I plan to freshen them up and put out a couple more. I think I've decided to go with the di-calcium phosphate mix that is mentioned on here a lot, problem is I can't find anywhere to get it. So basically where do you guys get di-calcium phosphate at?? Also I'm definitely open to any other suggestions....what do you guys think about the Whitetail Institutes 30-06 minerals or the Cutting Edge products.
