For example, if your soil tests at 8.0, this application rate will lower it to 7.0, an acceptable pH for a vegetable garden. Other options for lowering soil pH may include iron sulfate or aluminum sulfate, but they are more expensive than elemental sulfur and aluminum is toxic to nearly all but the most acid-loving plants. A lower lawn pH can be achieved with sulfur or a fertilizer made for acid-loving plants. An excellent way to lower the pH of small beds or garden areas is the addition of sphagnum peat. So, the response in soil pH decrease will not be immediate because it will take some time to react with the help of soil bacteria. Occasionally soil pH must be lowered, because either the plant requires acidic soil, or relatively high levels of base cations such as calcium and magnesium are present. bag; Applying organic, elemental garden sulfur is a safe and effective way to lower soil pH.
