There were wheat silos next to the storage location. As Swaghauler mentioned, the very fine dust from wheat is highly flammable and would easily contribute fuel to the explosion although just how much force it would have is not something I know about.
Just how much AN was at the storage site is open to question as because as Legbreaker mentioned, it is rumoured that Hezbollah was using the stockpile for bomb making purposes.
