guys are fritz haber and carl bosch. his superiors in germany that he had perfected a reaction capable of generated ammonia, from -- he had figured out how to mine the air of nitrogen. carl bosch standardize it into an industrial process. osch.ow it as the haber-b mining this from the air began in 1913. what else are nitrates used for? >> explosives, like for a war. ? prof. sutter: munitions. we were just about to enter into world war i. this process would prove really critical to the german capacity to fight world war i. after world war i, there were all these industrially produced nitrates hanging around as farmers would then begin to turn to them. aroundhis long search the globe for nitrates, we have a fully industrialized process for producing nitrogen. the haber-bosch process after incredibly and energy-intensive process, we would not need guano or menhaden anymore. at least four people who could afford it. this brings to a conclusion these various metabolic rifts occurring throughout this period . i talked about th

and then later, this chemical engineer by the name of carl bosch standardized it into an industrial process. we know it as the haber-bosch. industrial production of nitrates mind from the air began in 1913. what else are nitrates used for? rachel, hold your thought until we get the mic over there. rachel: explosives, like for a war. ? prof. sutter: munitions. we were just about to enter into world war i. this process would prove really critical to the german capacity to fight world war i. and this process would prove really critical to the german capacity to fight world war i. and then, after world war i, there were all these industrially produced nitrates hanging around as farmers would then begin to turn to them. and here, in a sense after all of this 19th century searching around the globe for nitrates, we have a fully industrialized process for producing nitrogen. alright, the haber-bosch process after the 1930's, and incredibly energy-intensive process, we would not need guano or menhaden anymore. at least for people who could afford to buy fertilizer on the open market. bringhis helps
