How do I make potassium nitrate from wood ash?
Urea and any metabolized ammonia are oxidized by the bacteria in the manure to nitrate which react with potassium carbonate (in the wood ash). This forms a mix of soluble potassium nitrate and insoluble calcium and magnesium carbonates. The soluble potassium nitrate can then be drawn off from the mix in the liquid.

KNO3 has a wide solubility range in water ~13g/100mL at 0C to ~250g/100mL at 100C. So it depends on how much you have and what else is present in solution. One approach would be to reduce the volume of solution until it saturates at the boiling point then allow it to slowly cool. This should grow large crystals of reasonable purity. Filter and dry the crystals; repeat with the mother liquor or simply allow the water to evaporate depending on what else is present.

Wood contains potassium ions which, when burned, are converted to potassium oxide (K20) that remains in the ashes. In fact, wood ashes contain up to 4% potassium. Soaking the ashes in water converts the K2O to potassium hydroxide by the reaction:
K2O + H2O -> 2KOH
The term “potash” refers generally to all manufactured water-soluble potassium compounds since they were first derived from ashes soaked in a pot of water. When first discovered in 1808, the element was named potassium after the term potash.

Mill it. Use a ball mill if you have one, and if you’re planning to make gunpowder, you should have one. Otherwise you can mill small amounts (a few ounces) of potassium nitrate in a blade-type coffee grinder.
If you are, in fact, making gunpowder, and you have a ball mill, you don’t need to mill the nitrate separately. Just toss it all in together.

The wood ash is only half of the equation. Wood ash, or any other biological ash has a lot of potassium in it in the form of K+ ions. You need to set up some organic decomposition pits to let the warm, wet biologicals go into action in the presence of air to get the nitrate part. You trickle water through the pit and collect and dry the runoff. It will contain a lot of potassium nitrate as well as sodium and other nitrates and residues. You “make up” for any missing potassium with the wood ash. In the end potassium nitrate will be the most soluble compound in the products so you can either wash it out first or dissolve the whole mess and precipitate out everything that is not potassium nitrate.
During the civil war the confederate government issued instructions to farmers how to make potassium nitrate for gun powder.

Nothing won't happen, I think. At least until you boil the water. If you add more KNO3 than sugar, and boil the water, then you will get gunpowder (or something like that). If you add less KNO3 than the sugar and boil the water, you will get solid rocket fuel.

It’s a very long and complicated process that involves a big heap of animal dung and urine. When treated properly, that exudes potassium nitrate crystals on its surface, If your labor was free, and you had horses or cows and a big covered space where the smell would not bother anybody, you could do it. It’s much cheaper and easier to just go to your local farm supply and buy it for your hydroponic project by the 50 pound bag.
Buy a lot and they’ll probably turn you in to the ATF.
