Industrial fixation is a synthetic method of converting atmospheric nitrogen to nitrogen oxides or ammonium ions that plants and other organisms are able to use. Fertilizer manufacturers use these processes in creating their products.Know More
Manufacturers have three forms of industrial fixation from which to choose, the most common of which is the Haber or Haber-Bosch process. It involves heating nitrogen and hydrogen in a pressurized vessel with iron as a catalyst. The reaction produces ammonia, which is useful for plants and ultimately those organisms that consume them. A second option is the cyanamide process. The manufacturer heats calcium carbide in an atmosphere of pure nitrogen to form calcium cyanamide, a plant fertilizer. The third option is the electric arc process. The arc causes nitrogen and oxygen in the air to form oxides that bubble through water to form nitric acid.
Even though living organisms require nitrogen for life, most are unable to break the strong triple bond between two nitrogen atoms when the substance is in its elemental form. The element must be fixed to be metabolized.
Over 90 percent of the nitrogen fixation in the world occurs through the natural process of lightening and microorganisms known as diazotrophs. Examples of diazotrophs include bacteria and blue-green algae. Other diazotrophs exist in symbiosis with termites, plants and protozoa.Learn more about Industries

There are several insects that prey on cotton plants, including boll weevils, cotton leafworms, cotton fleahoppers and cotton aphids. Cotton plants are relatively hardy crops, but are susceptible to damage from a number of bugs and insects. They are attacked by many types of predatory species, including beetles, mites, spiders and aphids.Full Answer >
Oil has many industrial and household uses. Crude oil, a non-renewable fossil fuel, is refined into gasoline and diesel fuels that power automobiles and other engines. Oil is also used to lubricate moving metal parts in order to reduce friction and heat. Kerosene and propane are by-products of oil refinement and are commonly used for home heating and cooking.Full Answer >
Companies use quarterly earnings reports to communicate performance and financial health to investors or shareholders, according to Investopedia. These reports are released at the end of each quarter and include financial items such as net sales, net income, earnings from continuing operations and earnings per share.Full Answer >
