According to Cascade Minerals, fall is the perfect time to be adding rock dusts to improve your soil. its probably a better idea to add minerals in a broad spectrum rather than individually, unless your tests show there is one specific deficiency.
I also ran across a caution that rock dusts may contain heavy metals, so that's something to look out for.
This article mentions several ways to remineralize soil -- there is no seaweed in Alabama - & I guess if there was seaweed in the gulf it would be full of oil.
