  2. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air. It is a colorless, mobile liquid whose viscosity is about one-tenth that of acetone (i.e. roughly one-thirtieth that of water at room temperature). Liquid nitrogen is widely used as a coolant.

    en.wikipedia.org/wiki/Fertilizer

    Agricultural and chemical minerals are very important in industrial use of fertilizers, which is valued at approximately $200 billion. [48] Nitrogen has a significant impact in the global mineral use, followed by potash and phosphate. The production of nitrogen has drastically increased since the 1960s.

  4. Nitrogen - Wikipedia

    Air balloon submerged in liquid nitrogen. Liquid nitrogen is a cryogenic liquid which looks like water. When insulated in proper containers such as dewar flasks, it can be transported and stored with a low rate of evaporative loss. [99] A container vehicle carrying liquid nitrogen. Like dry ice, the main use of liquid nitrogen is

  5. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    Derelict soils occur where industrial contamination or other development activity damages the soil to such a degree that the land cannot be used safely or productively. Remediation of derelict soil uses principles of geology, physics, chemistry and biology to degrade, attenuate, isolate or remove soil contaminants to restore soil functions and ...

    en.wikipedia.org/wiki/History_of_fertilizer

    In France, Jean Baptiste Boussingault (1802–1887) pointed out that the amount of nitrogen in various kinds of fertilizers is important. Metallurgists Percy Gilchrist (1851–1935) and Sidney Gilchrist Thomas (1850–1885) invented the Gilchrist–Thomas process, which enabled the use of high phosphorus acidic Continental ores for steelmaking.
