I see you are in Florida. Indeed, Florida did pass some legislation greatly limiting the amount of phosphate in lawn fertilizer. (I believe it does not affect commercial Ag.) A handful of midwest states plus Maine have similar laws.
It may have passed in 2007 but went into effect this year. Or maybe it just passed this year after near-misses since 2007. Anyhow, it has been in the works for several years and did finally pass, but I can't find a link to the exact bill. Sorry.
Edit...this may help:
