Supplies of Sulphur (Elemental or Sulphate) Plants take up sulphur in the sulphate (SO4) form. The sulphate form is water soluble, and being an anion, is readily leachable.

The elemental form of sulphur needs to be broken down into the sulphate form before becoming available to the plant. This is achieved by bacteria (Thiobacillus spp.) naturally present in the soil, which digest the sulphur and convert to sulphate.
