Gypsum is neutral in pH, and since it has no carbonate ion as part of its makeup, it will not neutralize acidity. However, it is much more soluble than most lime products (about 200 times as soluble), so it does make a very good source for soluble calcium and sulfate. In other words, applying gypsum to the soil will raise the calcium and sulfur levels of the soil, but it will not raise the pH.
