Question about Mother Of All Blooms (MOAB) NPK 0-52-32 Claim!!!

I don't know if I'm missing something, but the other day I was holding my MOAB package and I noticed that it is derived from Mono-Potassium Phosphate and Mono-Ammonium Phosphate. Now the Mono-Ammonium Phosphate contains 12% nitrogen.

How come the label of MOAB indicate an NPK of "0"-52-32 then?! Is this label just hogwash!

Also if someone with experience in mixing fertilizers could tell me, how to get NPK of 0-52-32 from mixing Mono-Ammonium Phosphate (NPK 12-61-0) with Mono Ammonium-Phosphate (0-52-34)? Even if I excluded the Nitrogen content, this seems mathematically impossible!


Appreciate your answers.

My guess is they use the mono-ammonium phosphate in such a small amount that it's negligible. They probably just want it on the label to make it seem that you're getting more than the MKP at 5 - 6 times the cost. They sell MOAB for $12 100 grams. You can buy a pound of MKP which is the same thing as MOAB for less than $10. That MOAB is a ripoff.

Thank you. That makes perfect sense actually.

I also think that MOAB is a rip off now that I know a little more about fertilizers. In my country MKP is very cheap indeed.
