Fertilizer: The Invention That Made 8 Billion People Possible

#history #documentary #historyoffertilizer #fertilizer The History of Fertilizer — The Chemical That Keeps Half the World Alive Fertilizer: The Invention That Made 8 Billion People Possible Fertilizer looks ordinary. Its history is anything but. This documentary follows humanity's struggle with exhausted soil from manure, night soil, guano, and Chilean nitrate to the Haber-Bosch process: the breakthrough that learned to pull nitrogen from the air and turn it into food. It is a story of Oppau, Fritz Haber, Carl Bosch, chemical warfare, industrial explosions, Norman Borlaug, the Green Revolution, modern agriculture, dead zones, natural gas, and the fragile global system that now helps feed roughly half the people on Earth. The same chemistry can make wheat grow, keep billions alive, prolong a war, or erase a town. And some of the nitrogen in your body may have passed through an ammonia reactor before it became part of you.
