Now I'm just a make-believe farmer but when I was a real farmer, I would never buy fertilizer with fillers. So 19-19-19 was real common.

If you take the common ingredients of commercial fertilizer and mathematically make the N,P, and K equal, you can't do any better than 19-19-19. So 19+19+19 = 57%. The other 43% of the weight wasn't added, it's just there because it's part of the molecule, just like when you buy bananas, the peels get weighed but you don't eat them. (I give mine to the goats).
But the fertilizer companies want to make some $$$ at this. So they blend in some filler. In the example of Boss using 500 lbs. of 10-10-10, he's got 50 lbs. each of N,P, and K.
Instead of applying 500 lbs. of 10-10-10, he could have applied 264 lbs of 19-19-19. But around here nobody's going to bag up 19-19-19.
It's kind of wasteful that we end up paying the costs (transportation of needless weight). That's what I meant when I said "when I was a real farmer" the NPK came from a blend plant without fillers added. Nowadays, being a "make-believe" farmer, in the smaller quantities I buy, I'm forced to pay for added fillers.
