Given the extensive and continued use of calcium sulfate as a fertiliser and for chemical treatments of soils and its natural occurrence in the environment, it is considered that calcium sulfate would not have a detrimental effect on soil microorganisms.
Calcium sulfate, calcium and sulfate ions are ubiquitous in the
environment. Calcium is an important constituent of most soils and the
minerals found in soil are mostly compounds of calcium with other
substances. Furthermore, calcium sulfate, as Gypsum, is used as an
inorganic fertiliser to improve soil quality. Important applications
• for the reclamation of sodic soils through ion exchange (calcium
• to reduce run-off water and its resulting erosion in dry agricultural
areas as an ameliorant for acidic subsoils and soils in forestry
• to improve Ca- and S-nutritional elements in agriculture (rape and
• Gypsum is also useful as an additive for soils with high levels of
Sulfur-reducing bacteria comprise several groups of bacteria that use
sulfate as an oxidizing agent. Calcium sulfate is not toxic to these
forms of bacteria and since it is used to enhance the quality of soil,
it is expected that calcium sulfate would not be toxic to soil
