I am not sure how to isolate KNO3 from fertilizer. But you can get KNO3 from Specracide Stump Remover. You can buy this from Walmart or From Lowes and it is 98% KNO3. This is great stuff but I am not sure how much longer you are going to be able to buy this stuff so easily because of naughty people running around blowing things up

I don't think you're qualified to be working with these chemicals.

Just wondering: how do you know that the fertilizer is 28% KNO3? Most fertilizers merely give the NPK values, which are percentages, but not of a specific substance.
