  • Through the 1800's, heavily populated countries in Europe such as Germany and Britain used guano from islands off the coast of Peru and salt petre from Chile as a source of natural nitrogen fertilizer

      We can see the evolution through of the use of ammonia
  • For a brief time the first factory turned out fertilizer. With onset of WW1 Germany needed munitions for its war effort. The factory was seconded to munitions and is credited or blamed with greatly prolonging WW1 and making WW2 possible.

      The use of ammonia prolonged the two world wars...moral cost of a convinienent good
  • It wasn't until the 1950's, after the first and second world wars, that the Haber process really started to affect farming. Ammonia stocks, diverted in wartime to make bombs and bullets, started being used to produce the synthetic nitrogen fertilizers used everywhere today.

      NH3
  • Its boiling point is about -27.4°F (-33.3°C) making it easy to liquefy at low temperatures.

      One can use this information to optimize the production of ammonia through the Born-Haber process
  • Ammonia is also used to produce salts such as ammonium nitrate and ammonium phosphate for use as commercial fertilizers. It is used in the manufacture of nylon and rayon and for scouring cotton, wool, and silk.

      Not only is ammonia solely used for commercial and manufactoring uses, but also can be utilized militarily. It can be used to make weapons and other instruments of war. However, is the cost of producing future weapons of mass destruction worth the civilian uses of ammonia?

      Can you use the bacteria to produce ammonia in mass amounts?
  • An especially important example involves Rhizobium bacteria in root nodules of leguminous plants, and is the basis for the common agricultural practice of growing legumes in rotation with other crops to enrich fields with available nitrogen.

  • Ammonia is manufactured by the reaction of hydrogen with nitrogen in the presence of an iron catalyst, which is known as the Haber-Bosch process.

      Production of ammonia
  • The largest use of ammonia is in fertilizers, which are applied to the soil and help provide increased yields of crops such as corn, wheat, and soybeans. Liquid ammonia, ammonia/water solutions, and chemicals made from ammonia, such as ammonium salts and urea, are all used as sources of soluble nitrogen. Urea, which is made from ammonia and carbon dioxide, can also be used as a feed supplement for cattle, aiding in the rapid building of protein by the animals.
