Biogeochemical cycles are of two types: gaseous and sedimentary. In gaseous nutrient cycles, the materials involved in circulation between biotic and abiotic components of biosphere are gases or vapours and the reservoir pool is atmosphere or hydrosphere, e.g., carbon, hydrogen, oxygen, nitrogen and water. In sedimentary nutrient cycles, materials involved in circulation between biotic and abiotic components of biosphere are
non-gaseous and the reservoir pool is lithosphere, e.g., phosphorus, calcium and magnesium. Sulphur has both sedimentary and gaseous nutrient cycles.
