The Sulfur Cycle

2. About the Sulfur Cycle:
The process by which Sulfur moves to and from minerals and the atmosphere is know as the Sulfur Cycle

3. Major Components Sulfur Cycle The Ocean Sulfate salts Pollution
Volcanoes
Rain

4. The Phases of Sulfur
The weathering of ricks is the first step to release the sulfur stored in the rocks.
Next, the sulfur comes in contact with the air turning the sulfur into sulfate.
Then the sulfate is taken up by plants and microorganisms and converted into organic form.
Finally, animals eat those plants which introduces sulfur into the food chain.

5. Sulfur nutrients and uses
Essential plant food for production of protein.
Promotes activity and development of enzymes and vitamins.
Helps in chlorophyll formation.
Improves root growth and seed production.
Helps with vigorous plant growth and resistance to cold.
Sulfur may be supplied to the soil from rainwater. It is also added in some fertilizers as an impurity, especially the lower grade fertilizers. The use of gypsum also increases soil sulfur levels.
