Iron and marine nitrogen fixation: progress and future directions.
A synthesis of the current understanding of potential iron limitation of pelagic nitrogen fixation is given, considering biochemical bases of Fe requirements and empirical observations of growth and Fe quotas of cultures and field populations of Trichodesmium. The potential for iron limitation of heterotrophic diazotrophy in the marine environment is also evaluated.
