Everyone is correct, though. You will never be successful lowering the pH of
any soil, permanently.

You can get a rough number for how much sulfur it takes by sending a
soil sample to the Texas Ag Extension Service's Soils Lab at A&M and
looking at the measure for "Excess Calcium".

My soil, probably similar to yours, would require on the order of
9,000 pounds of sulfur per acre to handle the top 6 inches (plow
depth). I leak a little Disposul (200 #) on it every year but that
takes something like 30 years to even come close and by that time what
is below 6 inches probably leaks up.

I also add quit a bit of phosphorus as that goes into calcium
phosphate. So with the calcium sulfate and calcium phosphate I am
creating, I will, if I live long enough, end up with a "plaster" yard.
