Non Biological Nitrogen fixation: By Lightning and The Haber–Bosch process

Botany optional for UPSC; Non Biological Nitrogen fixation: By Lightning and The Haber–Bosch process Nitrogen fixation is the process by which atmospheric nitrogen gas is converted into salts of nitrogen such as, ammonia, nitrate and nitrogen dioxide . Physical Nitrogen fixation, through geochemical processes, and industrially through the Haber–Bosch process. Lightning contributes about 10% of the total nitrogen fixation. Usually atmospheric nitrogen fixation (or Natural) by lightning occurs in rainy season during lightning or thunder storms. The Haber-Bosch Process is an industrial method of reacting nitrogen and hydrogen gas to produce ammonia.  It involves one mole of diatomic nitrogen and three moles of diatomic hydrogen per two moles of ammonia. Haber Process Equation: N2 + 3H2 → 2NH3 The Haber-Bosch process begins with the invention of the Haber process at the dawn of the twentieth century. The process allows the economical atmospheric nitrogen fixation in the form of ammonia, which in turn allows for the industrial synthesis of various nitrogen fertilizers. Well before the start of the industrial revolution, farmers would fertilize the land in various ways, mainly using feces and urine. The 1840s works of Justus Von Liebig identified nitrogen as one of the important nutrients. Over time children used to play in the fields and farmers reckoned that that was the reason that their children were so strong. In 1909, German chemist Fritz Haber made scientific history when he demonstrated synthesizing ammonia from atmospheric nitrogen and hydrogen. Later in 1911, the method was significantly improved by another German chemist Carl Bosch, which made the reaction more efficient for industry. #nitrogenfixation #haberboschprocess #nitrogengas
