When soil is deficient in sulfur, plants can be short and spindly, with yellowish veins on their leaves and poor, or nonexistent, flower and fruit production. In the soil sulfur interacts with plant roots in two ways. First, sulfur, when concerted by bacteria to sulfuric acid, lowers soil pH, increasing plant-root access to many nutrients. Second, sulfur plays a critical role in the formation of plant tissue proteins and vitamin formation.
I have used sulfur in the past for 1 reason, to lower soil pH
Let’s start with Lowering Soil pH with Sulfur:
Test several soil samples of soil from your intended planting area for the rating of acidity or alkalinity, commonly called pH. The pH level of your soil will determine how much elemental sulfur you add. Determine the amount of sulfur you will need to lower your soil pH to a food growing level for your particular plants or planting area. Do this by using a university extension service or commercial chart or garden calculator. For most garden annual, vegetables and perennials, your goal is to create neutral-to-slightly-acidic soil, with pH of 6.5 to 7.0. Please pour or rake the sulfur evenly over the entire planting area. Turn soil, with the shovel or spade, to a depth of at least the length of the tool blade, mixing sulfur thoroughly with soil. Rake if necessary to break up clods of dirt. Let the soil sit for at least one week and up to one month before planting. This lessens the danger of sulfur being converted by excess water into hydrogen sulfide, which is corrosive to plant roots and increase the opportunity for soil bacteria to convert sulfur into root-accessible sulfuric acid before you plant.
