How a century of ammonia synthesis changed the world
On 13 October 1908, Fritz Haber filed his patent on the "synthesis of ammonia from its elements" for which he was later awarded the 1918 Nobel Prize in Chemistry. A hundred years on we live in aExpand

Ammonia: emission, atmospheric transport and deposition
The global emission of ammonia (NH 3 ) is about 54 Mt N. The major global sources are excreta from domestic animals and fertilizers, but oceans, biomass burning and crops are also important. AboutExpand

Review and parameterisation of bi-directional ammonia exchange between vegetation and the atmosphere
Abstract. Current deposition schemes used in atmospheric chemical transport models do not generally account for bi-directional exchange of ammonia (NH3). Bi-directional exchange schemes, which haveExpand
