Anhydrous Ammonia (NH3) Ammonia (NH3) is a pungent, colorless, toxic gas more commonly called anhydrous ammonia. When ammonia is added to carbon dioxide to produce urea, it is the building block chemical for lots of agricultural fertilizers. Until the end of the nineteenth century, approximately all fertilizers were organic in the modern sense. They were obtained from composting agricultural, animal and human waste. As the world population grew, so did its need to feed itself. Far to many years of slash and burn agriculture, along with harvesting the same crops in the same fields for generations had led to critical soil depletion. Imported guano was getting costly as crops yields were falling. Haber’s process of directly combining nitrogen and hydrogen to create ammonia was the genesis of an entire synthetic fertilizer industry in Europe and North America. Once premium quality, plentiful and affordible ammonia came on the market, in addition to agricultural chemicals, a new synthetic dye industry developed, as well as the first successful automatic document duplication process. Nowadays most world-scale ammonia is produced and directly utilized in the agriculture industries.
