WebNitrogen Fixing Bacteria. Nitrogen, along with potassium and phosphorus, is one of the top essential nutrients for crop development, as it is responsible for photosynthesis and chlorophyll concentration. Nitrogen … Historical A method for nitrogen fixation was first described by Henry Cavendish in 1784 using electric arcs reacting nitrogen and oxygen in air. This method was implemented in the Birkeland–Eyde process of 1903. The fixation of nitrogen by lightning is a very similar natural occurring process. The … See more Nitrogen fixation or biological nitrogen fixation (BNF) is a chemical process by which molecular nitrogen (N 2), which has a strong triple covalent bond, is converted into ammonia (NH 3) or related nitrogenous compounds, … See more Biological nitrogen fixation was discovered by Jean-Baptiste Boussingault in 1838. Later, in 1880, the process by which it happens was discovered by German agronomist See more Nitrogen can be fixed by lightning converting nitrogen gas (N 2) and oxygen gas (O 2) in the atmosphere into NOx (nitrogen oxides).
