So is that the point? To lower the pH? I thought a neutral 7.0 was a good thing. Also, at what level should the sulfur "ideally" be?

Ummm, yeah. Neutral is not optimal - grasses do best between pH 6.3 and 6.8. As the pH rises above 6.8, some elements become less available and the chemistry changes. As far as Sulfur is concerned, good numbers are between 20 and 300, dependent on the rest of the nutrients. It is also defined as needing to be between 30% and 50% (I use 40% unless there are mitigating factors) of the Phosphorus level. Is that complex enough for you?

Some food for thought; I was just reading my recently acquired copy of the 2012 Farmer's Almanac. There was a comment in the soil section stating that soil that is normally slightly acidic could go toward alkaline (base) over an extended dry spell. If you look at my soil results from July, my pH was 6.8. Then we had severely dry/hot weather immediately following, and even a drier than normal fall. So I guess if the Farmer's Almanac is right, then this could be why I'm seeing a rise in pH from July to December? If that's true, would you still recommend adding sulfur, or will it "snap" out of it this spring?

The only way that I can think of for pH to rise during a dry spell would be due to a suspension of the OM-decay cycle due to lack of water that supports it. That process is slightly acidic until it completes.

A 0.2 pH difference from any one sample to any other is not surprising AT ALL. The correct answer is probably in the middle.

That all said, your question is similar to "if a deck of cards is thrown up in the air, what card winds up on top?".

There is no way to answer your question.
