BM,

A lot of that granular mix has around 20% Calcium, and 10% phosphorus-or percentages close, with 30 to 50% salt. I don't know if that dynamite stuff is in that same catagory, maybe just a powder/attractant type stuff, but I've never used it. I've had good success notching out a 1-2' stump with a chain saw, and pouring the mineral mix on the stump. With rain, it eventually coats the stump and the deer not only eat the bark, stump, roots, but the surrounding dirt and debris as well. I have sandy soil, so I did this to try and keep the mix from disappearing into the ground.
