I did some quick research and all resources claim it's 100% potassium nitrate.

quote:
"I use Spectracide stump remover. It's 100% potassium nitrate. I found mine
at Lowes. It was in the insecticide/herbicide section in a green bottle with
a tip on it. $4.95 for 493 grams. That's enough to raise 10 gallons of water
to 11345 PPM of Nitrate and 7314 PPM of Potassium."
