Efficient use of nitrogen in agriculture

Abstract

In the lyrics of one of their most well-known songs, the British rock band Dire Straits wrote “we have just one world, but we live in different ones”. This can also be said about the Nitrogen (N) world, where deficit of reactive N is limiting food production in many areas, still causing hunger today in the developing world, while excess of reactive N causes inefficient use and environmental problems in mainly the industrialized world.
