Possible KN source?

[bungalooping]

Hello guys I saw an local online website that sells Potassium Nitrate, it's supposedly an agricultural website selling fertilizer and stuff and they're selling KN 13-0-46, which is 13% Nitrogen, 46% K2O, the 0 from my understanding stands for 0% Phosphorus, so I guess the 41% of mass left is just other filler materials?

Question is would this be enough to kill me? How would this work?

Thank you all

You need Nitrite not Nitrate - sorry.
