Sulfur in a sentence

Sulfur deficiency has become widespread in many countries in Europe. citation citation citation Because atmospheric inputs of sulfur continue to decrease, the deficit in the sulfur input/output is likely to increase unless sulfur fertilizers are used.

The difference between the two is that sulfate sulfur forms, such as gypsum or ammonium sulfate, contain readily available sulfur, while elemental sulfur must be oxidized to sulfate prior to plant uptake.

Because of the sulfur dioxide produced during the process of melting sulfur, the craft of sulfur inlays was soon abandoned.

If liquid sulfur above 190°Celsius is frozen very rapidly, the resulting sulfur is amorphous or "plastic" sulfur.

Limit sulfur-rich foods: If you notice that certain foods trigger sulfur burps, try reducing your intake of those items.

While sulfur has been studied as a cooling agent—largely inspired by volcanic eruptions that inject sulfur dioxide into the atmosphere—the material poses significant risks, including ozone depletion and acid rain.

Since then, most power plants have been required to install equipment that pulls sulfur emissions from the smokestack, but some sulfur still slips into the atmosphere.

The sulfur smell is either hydrogen sulfide directly or an iron bacteria problem that's providing a welcoming environment for some sulfur bacteria.

A strong odor called "smell of sulfur" actually is given off by several sulfur compounds, such as hydrogen sulfide and organosulfur compounds.

Calcium and sulfur are also produced by weathering, but acid deposition is an important source of sulfur in many ecosystems.

Carbon-sulfur compounds Important inorganic carbon sulfur compounds are the carbon sulfides carbon disulfide (CS 2 ) and carbonyl sulfide (OCS).

Crude oil may be considered light if it has low density or heavy if it has high density; and it may be referred to as sweet if it contains relatively little sulfur or sour if it contains substantial amounts of sulfur.

Dyar and Gunter, pp. 644–648 Sulfides main Red cinnabar (HgS), a mercury ore, on dolomite The sulfide minerals are chemical compounds of one or more metals or semimetals with a sulfur; tellurium, arsenic, or selenium can substitute for the sulfur.

For example, sulfur trioxide is not produced quantitatively by the combustion of sulfur.

Fungicide and pesticide Sulfur candle originally sold for home fumigation Elemental sulfur is one of the oldest fungicides and pesticides.

Green and purple sulfur bacteria are thought to have used hydrogen and sulfur as electron donors.

However, the sulfur content of traditional gunpowders caused corrosion problems with Cordite Mk I and this led to the introduction of a range of sulfur-free gunpowders, of varying grain sizes.

In the 1890s, Herman Frasch came up with the solution of liquefying the sulfur with superheated steam and pumping the sulfur up to the surface.

In the 1960s, the Tennessee Valley Authority National Fertilizer Development Center began developing sulfur-coated urea; sulfur was used as the principal coating material because of its low cost and its value as a secondary nutrient.

In this method, superheated water was pumped into a native sulfur deposit to melt the sulfur, and then compressed air returned the 99.5% pure melted product to the surface.
