Sulfur Cycle

All about the Sulfur Biogeochemical Cycle

We invite you to know everything related to the sulfur cycle , its main characteristics, reservoirs, stages, flow, its importance for living beings and the impact of the human being on it.

What is the Sulfur Cycle ?

It consists of that chemical, biological and complex process where sulfur can be found in nature in its various forms or oxidation states.

What are the Sulfur Cycle Characteristics?

Non-metallic element of yellow color, very characteristic , tasteless smell , the tenth most abundant on the planet, is part of the animals or other molecules such as coenzyme, fundamental in the health of different organisms or ecosystems , combined with oxygen and It goes through different oxidation states.

What are the Sulfur Cycle Reservoirs?

Undoubtedly, that most of the sulfur is found in minerals and ocean sedimentary rocks. In the atmosphere, both natural and human factors.

What are the Sulfur Cycle Stages?

This cycle involves the movement of sulfur through the atmosphere, the hydrosphere, the lithosphere and the biosphere. In this tour, this element goes through 4 very important chemical stages such as:

Mineralization; process where organic sulfur is transformed into inorganic, also as hydrogen sulfide, elemental and sulphide-based minerals. Subsequently, the oxidation of hydrogen sulfide, elemental and other minerals to form sulfur dioxide in the environment. The reduction of sulfate to sulphide to be assimilated by organisms, microbial immobilization and finally its incorporation organizes sulfur.

What is the Sulfur Cycle Flow?

Formed by compounds; atmospheric, organic, inorganic, reduced sulfur and sulfates that are absorbed by plants, animals consume it and finally moves throughout the food chain.

Built into the ground; by atmospheric deposition, fertilizers of animal origin, plant residues, fertilizers and rock wear.

Removed from the ground; by plants by absorbing sulfates by their roots, crops, volatilization of reduced compounds, filtration, runoff, erosion, volcanoes, gases from organic decomposition,

What is the Importance Sulfur Cycle?

Sulfur is very important as a nutrient for plants and animals , being a vital component of amino acids and other biochemical compounds. Living beings satisfy their sulfur nutritional needs, by assimilation from the environment.

It is also essential as an ingredient in the formation of chlorophyll, building proteins, enzymes and vitamins . Also, commercial uses in gunpowder, matches, insecticides and fossil fuel production.

Definitely, the sulfur cycle is that process where it is transported in nature by air, soil, water and all living beings. It consists of the mineralization of organic sulfur to sulphide, its oxidation to sulfate and its reduction to sulphide.

Plants perform their functions by means of sulfur in the form of sulfate , primary or herbivorous consumers incorporate it into their body, and then when they are consumed by carnivorous animals they acquire sulfur in their tissues, these when they die from the bacteria they convert sulfate residues by decomposition pass to the ground and again be absorbed by the plants starting the cycle once more.

Finally, the impact of the human being on the sulfur cycle goes; from the burning of fossil fuels that release hydrogen sulfide gases into the atmosphere, and generating acid rain by sulfur dioxide ; which becomes sulfuric acid affecting different aquatic ecosystems.
