The sulfur cycle shows how immobilization and mineralization lead to elements being recycled by plants and microbes.An essential element of this recycling process is the storage of nutrients for plant use.Many mineralized nutrients easily leach from soil.This loss is reduced by soil flora,which capture nutrients for their own use. When they die in the rhizosphere,the nutrients are available again to plants.Therefore,soil organic matter and life can be seen as a means of nutrients storage
