Desert soil here, I have added sooo much organics over the past 3 years (my head spins). In addition to at least 5 inches of coop compost over the last 3 months. The soil test also shows almost zero nitro, but good Phosphorus and I think medium potassium. I expected all the poop to lower the ph. I guess another trip to the Depot....I only know what I've read, Hosspak.
Here is a pdf from Utah State University: Soil Problems, High pH
If your soil is clay, you may want to go with gypsum. It is used quite often around here where there is clay type Palouse soil.
Of course, beyond the elemental sulfur, an organic choice of just a good amount of organic matter will lower pH. Peat is supposed to be quite acidic, as well.
