Can you rephrase the question into the form of a question please!
Do you have soil with a low PH? If so it will make the soil more acidic when the sulfate ion is released and becomes Sulferic acid. This also adds nitrogen to the soil.
I don't know what dirt you were using nor do I know what soil you are currently using. If your soil had a low PH and you wanted to change that PH I assume you could use it.
