Some condition that is triggered by it being burried in earth instead of being in a storehouse.
An agent that slowly reacts with oxygen/water, to make the trigger/reaction mass unusable or something? Or one that causes it to slowly release the chemical energy to the ground, after a while.
In what form? Like a really hot rock that warms the earth around it for a few decades? That’s dangerous in itself, and, like my example about electrical batteries, susceptible to their own runaway reactions that cause fires or explosions.

Ok, bad idea. But making the trigger/reaction mass unusable?
