Did you catch this part: The experiment vindicated Martin's hypothesis. As predicted, the iron supplement stimulated plant growth, verifying that at least some phytoplankton species suffered from iron deficiency. But the anticipated drawdown of carbon dioxide never materialized.

Other factors also limited the iron's effectiveness (SN: 3/5/94, p.148)
