Hi there everyone.
Is it possible to extract potassium nitrate from NPK fertilizers?
Can I remove P leaving only N & K.
Currently I could only find 15 - 15 - 15

Thanks everyone
 
You need either sodium or a potassium nitrate fertilizer.
You can get nitrates from dirt, but who wants to spend years getting a little bit of nitrate salt, when the time could be spent educating yourself and recovering gold.

You can precipitate the Phosphorus as Calcium Phosphate,or go to your local hardware store and buy some stump remover, making sure the primary ingredient is KNO3, and save yourself the trouble.
 
It depends on your jurisdiction. Some locales, for some reactionary reasons, have limited access to formulations that they consider a threat.
A few years ago, I went to the local feed and seed store and ordered 3 sacks of Ammonium Nitrate prills. It took about 3 months before the authorities decided that I wasn't a threat and let me have them.
