First choice of sulfur in high pH soil in order is Elemental sulfur, aluminum sulfate if you need aluminum this is great source, ammonium sulfate any nutrient you need in the sulfate form would help. Ammonium sulfate will not lower pH as fast as elemental and aluminum. Stay away for calcium sulfate and good luck.
