I’ve read that sulfuric acids have been used in the production of chemical phosphorous fertilizers to make the phosphorous from various sources more available to plants. I was wondering if I add bone meal to my soil and go back later and add an acidic fertilizer like say, ammonium sulfate, would the acidity of the ammonium sulfate make the phosphorous in the bone meal more available to the plant sooner? Or possibly render some phosphorous ‘locked up’ in the soil available again?

Ammonium sulfate or any other acid forming fertilizer will not help make the bone meal more available. The best bet is to get your pH neutral to slightly acidic and you will make most nutrients as available as possible. Most phosphorus is quickly tied up in the soil.
