One of the more interesting fertilizers I've played with was some
300,000 year old bat guano from one of the Texas Caverns. I aquired it
from deep in the cave with permission from the then manager when I
worked there 24 years ago. ;-)

Had to be careful with it as it was quite rich. Very, very high in
Nitrogen.
