Phosphate Holdings: An Undiscovered Agricultural Gem

I'm confused by two passages in this post:

Phosphate Holdings (PHOS.PK) is the sole owner of Mississippi Phosphates, a producer of diammonium phosphate.

and

Another possible reason for the cheap stock is that PHOS has no source of phosphates of its own, but must buy it from Office Cherifien des Phosphates, the Moroccan state phosphate monopoly.

These statements seem contradictory, or do I just not understand what the difference between "diammonium phosphate" and "phosphates?" What am I missing?
