It think "was" is the right term here. Since it has been prominently used for homemade bombs (militias, WTC I), its trade has been somewhat restrivted, i.e. if you are not a farmer or a certified pyrotechnician, trying to buy large quantities will draw the attention of the authorities.

In this case, that may not be a problem (would anticipate that one could apply for proper use permits), and in any case I know enough farmers...   

It used to be available in 50-lb sacks quite readily - we used it as a de-icing compound as it's better for the surrounding vegetation than plain salt.  That was pre-911, though.
