I add the extra bag of salt because they hit it a whole lot better than without. I also will add the dried molasses to my gravity feeders that have corn in them. I might be mistaken but it seems to me the new dirt bag attrqctaint is pretty much dried molasses. Once the deer find the mineral they will literally start digging a crater getting the molasses out of the ground. One good rain and it seeps in the soil. Add it to corn and they will try to eat the feeder when it runs out lol.
