520			_aThe industrial synthesis of ammonia from nitrogen and hydrogen, making possible artificial fertilizers, was of fundamental importance to the modern world. The expansion of the world's population from 1.6 billion people in 1900 to today's six billion would not have been possible without the synthesis of ammonia. The book begins with a discussion of nitrogen's unique status in the biosphere, its role in crop production, and traditional means of supplying the nutrient. He then looks at various attempts to expand natural nitrogen flows through mineral and synthetic fertilizers. The core of the book is a detailed narrative of the discovery of ammonia synthesis by Fritz Haber and its commercialization by Carl Bosch and the chemical company BASF.
