Fritz Haber received his Nobel Prize one year later, in 1919.
Prize share: 1/1
One of the most important plant fertilizers is nitrogen. Air is mostly nitrogen, but plants can only utilize nitrogen when it is part of chemical compounds. In about 1913 Fritz Haber developed a method for producing ammonia from nitrogen and hydrogen, which could be used to manufacture artificial fertilizer. When nitrogen and hydrogen gases pass through an apparatus at a controlled temperature, pressure, and flow rate, and in the presence of a catalyst, ammonia is formed in an energy-efficient process.
