I've used Black Majic and Buck Jam, the persimmon flavor. Didn't do very well with either, although the Buck Jam that I poured on a dead stump, well, the deer ate some of the stump. Was pretty funny. I've had the best luck w/ the following:

1 25# bag of crushed rock salt
1 25# bag of dicalcium phosphate
1 25# bag of trace mineral

Dig up the ground, pour a ratio of 1:1:2, respectively, straight onto the ground you just worked up. Mix it in really well, and let 'er go! They absolutely tear that stuff up!!! Use whatever you want to mix it, it doesn't matter, just use that ratio. I use a big coffee can.
