Optimizing Soil pH with Elemental Sulfur

One of the main challenges of desert gardening is the high pH levels of the soil, which can inhibit nutrient absorption by plants. To address this issue, elemental sulfur can be used to lower the pH level and create a more favorable environment for plant growth. Elemental sulfur undergoes oxidation in the soil, converting to sulfuric acid. This acid breaks down caliche, a hard layer of calcium carbonate found in many desert soils, and helps to make the soil more acidic.

To effectively lower the pH level of desert soil, it is recommended to apply 15-20 pounds of Dr. Q’s Soil Sulfur per 1,000 square feet of land. The sulfur should be tilled into the soil at a depth of 6-8 inches. It is important to note that sulfur application should be avoided during the hot summer months, as high temperatures can negate the desired chemical reaction. Additionally, it is crucial to use elemental sulfur instead of ammonium sulfate, as the latter will not produce the same pH-lowering effect.

Benefits of Using Elemental Sulfur:

  • Reduces soil pH and counteracts alkaline conditions
  • Breaks down caliche, improving soil structure and drainage
  • Enhances nutrient availability to plants
