They actually used to do this for real with bird guano, it was a vital part of industrial farming before they figured out how to make ammonia in a lab. There was even a war over it!
Bat guano was also used to a lesser extent, and Confederates used it during Civil War blockades to manufacture gunpowder.

Wasn’t that to harvest the nitrate, not the potassium?
Honestly I don’t know much about the chemical side, so you’re probably right.
