cheesenuget Posted September 26, 2008 Posted September 26, 2008 i got some realy cheap fertilizer today and i want to extract the potassium nitrate from it. the numbers are 15-15-30. 15% nitrogen, 15%Phosphoric Acid, 30%Soluable Potash and a little others. It is a soluable fertilizer. I herd that there are a few different ways to extract it, i was wondering how i could do it without spending a week of time for 500g of potassium nitrate. Does freezing it in water work? (a rumour) thanks.
big314mp Posted September 26, 2008 Posted September 26, 2008 Usually you can just buy KNO3 on its own as a fertilizer. Small bags are often sold as tree stump remover.
