On the Absorption of Ammonia from the Atmosphere
Published online by Cambridge University Press: 27 March 2009
Extract
Throughout the whole history of agricultural chemistry attention has been fixed upon. the ammonia in the atmosphere as a possible source of the nitrogen of vegetation, and without reviewing the early controversy that centred round Liebig, we may agree that the dispute was largely due to the exaggerated opinions then prevailing as to the amount of ammonia in the atmosphere. The most trustworthy determinations are the long series that have been carried out by Lévy at Montsouris, and they agree with other determinations by Ville, Schloesing and Muntz and Aubin. showing only from ·01 to ·02 of nitrogen as ammonia per million of air even in Paris, with a still smaller proportion in the air of the country.
