Abstract

The Fe:PO₄ ratio at which nutrient limitation of final cell yield shifts from one nutrient to the other was determined for 22 species of marine phytoplankton. Because some phytoplankton species have adaptations that reduce their dependence on combined N and Fe but not on P, it is concluded that PO₄ is the ultimate limiting nutrient of new production of organic C on a geochemical and evolutionary time scale, even though N and Fe are important growth rate-limiting nutrients on an ecological time scale. -from Author
