There are good, and frightening, reasons to closely follow the changes in the nitrogen cycle. We should not be surprised if the effects and costs of disturbing it turn out to be as dramatic as those for the carbon cycle. In addition, greenhouse gas emissions from nitrogen fertilizers are around 3% of global emissions, but they are not visible in greenhouse gas inventories. The abolition or drastic reduction in the use of chemical fertilizers is a pre-condition for a sustainable food system.
