I would be very cautious about using that quantity of sulfur. It is 
fungicidal and can cause nutrient excesses of elements such as iron as 
it oxidizes to sulfate. I would not consider your soil pH as too high 
compared to most of the drier portions of the western US. What is the 
sulfate-sulfur level on a soil test? Too much interferes with other anions.
