Using Sulfur to Lower Soil pH. You can make larger adjustments to your garden soil pH by using some form of sulfur. Sulfur lowers soil pH as it is broken down by bacteria in the soil and converted to sulfuric acid. Sulfur is most commonly added in the forms of aluminum sulfate, iron sulfate and elemental sulfate.
How to Reduce the Alkalinity of Soil. 1  Test the soil to discover its alkalinity level. Gather soil samples from the garden area. 2  Review the results of the soil test to determine the soil's pH. 3  Add elemental sulfur at a rate of 0.1 pounds per 10 square feet of loamy soil for every one-half unit you wish to lower the pH.
