Fritz Haber — German Scientist born on December 09, 1868, died on January 29, 1934

Fritz Haber was a German chemist who received the Nobel Prize in Chemistry in 1918 for his invention of the Haber-Bosch process, the method used in industry to synthesize ammonia from nitrogen and hydrogen gases. This invention is of importance for the large-scale synthesis of fertilizers and explosives. The food production for half the world's current population depends on this method for producing nitrogen fertilizers. Haber, along with Max Born, proposed the Born–Haber cycle as a method for evaluating the lattice energy of an ionic solid... (wikipedia)

Agricultural husbandry essentially maintains the balance of bound nitrogen.
The Swedish Academy of Sciences has seen fit, by awarding the Nobel Prize, to honour the method of producing ammonia from nitrogen and hydrogen.
Gaseous nitrogen combines with gaseous hydrogen in simple quantitative proportions to produce gaseous ammonia.
Under natural conditions, the soil does not lose its fixed nitrogen.
