Chosen answer: Davy Jones cannot set foot on land for ten more years. The jar of dirt is to represent land. Jack carries it with him so that he always has land with him so Davy Jones won't be able to get near him, or so Jack is supposed to believe.
Answer: The jar was to put Davy Jones heart in. He can't touch dirt ever again since he failed to keep up his duties which means he wouldn't be able to get his heart back.
