Tree Stump Removal With Potassium Nitrate
If you can access the roots of the tree, then you can dig holes in them too, as this will help the process go faster. Use up as much space as you can find on the stump. Remember, the more holes you have, the more saltpeter you can add. Add Potassium Nitrate. Now that your holes have been dug, proceed to pour the potassium nitrate into each of ...

Is there any substitute for saltpeter / sodium nitrate in …
Saltpeter is potassium nitrate, which does not directly cure meats.Bacteria convert nitrate into nitrite, which is the real preservative.Saltpeter can be replaced by a smaller amount of nitrite to get the same curing effect (most commercial cured meats do this), though a prolonged cure that converts nitrate into nitrite can develop more flavor.

Sodium Cyanide vs. Potassium Cyanide: What's the Difference?
It is a white, water-soluble solid commonly used in mining to extract gold and silver. Potassium cyanide (KCN), similarly, consists of potassium (K) ions and cyanide anions. It is also a white, water-soluble compound but has a slightly different application profile, including use in organic synthesis and electroplating.
