“Gaseous nitrogen combines with gaseous hydrogen in simple quantitative proportions to produce gaseous ammonia.”

“Agricultural husbandry essentially maintains the balance of bound nitrogen.”

“Under natural conditions, the soil does not lose its fixed nitrogen.”

“The field of scientific abstraction encompasses independent kingdoms of ideas and of experiments and within these, rulers whose fame outlasts the centuries. But they are not the only kings in science. He also is a king who guides the spirit of his contemporaries by knowledge and creative work, by teaching and research in the field of applied science, and who conquers for science provinces which have only been raided by craftsmen.”

“The Swedish Academy of Sciences has seen fit, by awarding the Nobel Prize, to honour the method of producing ammonia from nitrogen and hydrogen.”
