  2. Nutrient management - Wikipedia

    en.wikipedia.org/wiki/Nutrient_management

    Nitrogen fertilizer being applied to growing corn in a contoured, no-tilled field in Iowa.. Nutrient management is the science and practice directed to link soil, crop, weather, and hydrologic factors with cultural, irrigation, and soil and water conservation practices to achieve optimal nutrient use efficiency, crop yields, crop quality, and economic returns, while reducing off-site transport ...

  3. Nitrogen generator - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_generator

    Glass industry: In glass production, nitrogen proves efficient as a cooling agent for electric arc furnace electrodes as well as to displace oxygen during process procedures. Metallurgy: The metal industry generally utilizes nitrogen as a means of protecting ferrous and non-ferrous metals during annealing. Also, nitrogen is helpful in such ...

  4. Abiological nitrogen fixation using homogeneous catalysts

    en.wikipedia.org/wiki/Abiological_nitrogen...

    Abiological nitrogen fixation describes chemical processes that fix (react with) N 2, usually with the goal of generating ammonia. The dominant technology for abiological nitrogen fixation is the Haber process, which uses iron-based heterogeneous catalysts and H 2 to convert N 2 to NH 3. This article focuses on homogeneous (soluble) catalysts ...

  5. Liquid nitrogen wash - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen_wash

    Liquid Nitrogen Wash is a process mainly used for the production of ammonia synthesis gas within fertilizer production plants. It is usually the last purification step in the ammonia production process sequence upstream of the actual ammonia production .

  6. Nitrogen and Non-Protein Nitrogen's effects on Agriculture

    en.wikipedia.org/wiki/Nitrogen_and_Non-Protein...

    Nitrogen is a fundamental nutrient in agriculture, playing a crucial role in plant growth and development. It is an essential component of proteins, enzymes , chlorophyll , and nucleic acids , all of which are essential for various metabolic processes within plants. [ 2 ]

  7. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.

  8. Ammonia production - Wikipedia

    en.wikipedia.org/wiki/Ammonia_production

    The Haber process, [5] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [6] [7] It converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction with hydrogen (H 2) using finely divided iron metal as a catalyst:

  9. Kjeldahl method - Wikipedia

    en.wikipedia.org/wiki/Kjeldahl_method

    It does not, however, give a measure of true protein content, as it measures nonprotein nitrogen in addition to the nitrogen in proteins. This is evidenced by the 2007 pet food incident and the 2008 Chinese milk powder scandal , when melamine , a nitrogen-rich chemical, was added to raw materials to fake high protein contents.
