Would You Use This Soil Containing Moss-Out & Lawn Food?

I currently have a ton of sod available to me that I'm considering using in raised beds.  The sod is all removed from a local school that is putting in a rain garden.  According to the maintenance people at the school, for at least the last few years they have only used the following chemicals:

Lilly Miller Ultra Green Fall and Winter Lawn Food:

Lilly Miller "Moss Out"

The Lawn Food doesn't totally freak me out.  I'd assume it's all synthetically created, but it also hasn't been applied for at least 6 months, and my hunch is that not much of it stays in the soils (though I don't have any proof or specific reason for saying that).

The Moss Out I know less about.  It lists Ferric Sulfate, anhydrous, as the active ingredient, and then contains a number of other "inert" ingredients, which is a big wild card in my mind.

Does anyone here more educated on chemistry than myself have an opinion on this? 

Would you use this in your garden? (Most of it will be used for annual vegetables, and will be topped with a few inches of better soil)

I would not use it this year, but I would use it in my compost heap.

That's probably fair.  The more I have been thinking about it, there are no herbicides or pesticides that I'm aware of, it's really just a ton of synthetic nutrients, so after some time to compost much of that would probably be gone.
