The manifold consequences of anthropogenic influences over the planetary nitrogen cycle have been investigated by many regional and international research groups.
Legumes already have a special place in the nitrogen cycle because they typically house live-in colonies of the bacteria that convert nitrogen from the air into ammonium.
The fixation process is what makes the nitrogen cycle so different from the carbon cycle.
However, a new study has shown that human activities, in particular industrial and agricultural processes, have also had significant impacts on the upper ocean nitrogen cycle.
The model, developed by researchers at the University of Exeter in collaboration with Plymouth Marine Laboratory, University of Leeds, UCL (University College London) and the University of Southern Denmark, reveals the sensitivity of the early oceans to the global nitrogen cycle.

These two groups carry out very different chemical processes, but they depend on each other because they are part of a larger nitrogen cycle that needs them both to continue spinning (see Page 32).
