Sulfur reduction occurs in plants, fungi, and many bacteria. [10] Sulfate can serve as an electron acceptor in anaerobic respiration and can also be reduced for the formation of organic compounds. Sulfate-reducing bacteria reduce sulfate and other oxidized sulfur compounds, such as sulfite, thiosulfate, and elemental sulfur, to sulfide.
Sulfur gases are potentially phytotoxic, however, they may also be metabolized and used as sulfur source and even be beneficial if the sulfur fertilization of the roots is not sufficient. Plant shoots form a sink for atmospheric sulfur gases, which can directly be taken up by the foliage (dry deposition).
No known function in humans, and is not taken up by plants. [11] Toxic in some forms. tin: 50: 4a: In mammals, deprivation causes impaired reproduction and other abnormal growth, [21] suggesting that it is an essential element. Tin may have a role in tertiary structure of proteins. Some plants are tin hyperaccumulators, possibly to deter herbivory.
Flowers of Sulfur can be used as a humid sulfur vapor test for creep corrosion. [12] Creep corrosion is the corrosion of copper or silver caused by sulfur pollution and causes failure in electronic products. Sulfur pollution includes elemental sulfur, sulfur dioxide, and hydrogen sulfide, which can oxidize metals. [13]
Plant nutrition is the study of the chemical elements and compounds necessary for plant growth and reproduction, plant metabolism and their external supply. In its absence the plant is unable to complete a normal life cycle, or that the element is part of some essential plant constituent or metabolite .
The important sulfur cycle is a biogeochemical cycle in which the sulfur moves between rocks, waterways and living systems. It is important in geology as it affects many minerals and in life because sulfur is an essential element (), being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in microbial respiration.

Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
A nutrient cycle (or ecological recycling) is the movement and exchange of inorganic and organic matter back into the production of matter. Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic.
