A nonmetal, sulfur is the 10th most abundant element in the universe, according to the Jefferson National Linear Accelerator Laboratory. Today, it's most common use is in the manufacture of sulfuric acid, which in turn goes into fertilizers, batteries and cleaners.
The most important form of sulfur for fertilizer is the mineral calcium sulfate. Elemental sulfur is hydrophobic (that is, it is not soluble in water) and, therefore, cannot be directly utilized by plants. Over time, soil bacteria can convert it to soluble derivatives, which can then be utilized by plants.ulfur is an essential component of all living cells. It is the seventh or eighth most abundant element in the human body by weight, being about as common as potassium, and a little more common than sodium or chlorine. A 70 kg (150 lb) human body contains about 140 grams of sulfur.
