I put the Apple Buck Jam on one of those 20 to 25 lb hard feed blocks and add it to the block a few times as the deerand animals work it down to nothing,the Jam soaks into the ground and over the months the deer will dig down in the dirt to get the minerals.Some times it takes a little while for the deer to work the jam and ground up but it has worked in my area.I also put out a regular white salt block and the deer use it a lot too,along with some Super 12 mineral from the local MFA Feed Store.I suggest trying different types of minerals to see what your Deer's like the best!
