I suggest that adding iron will make N and P pollution worse, not better. Further, it will likely be mostly ineffective.
Generally N and P arrive in rivers, and concentrate around coasts, especially round estuaries and deltas. Iron limitation is mainly in open oceans. Adding iron to littoral waters will be generally useless. N pollution works by making the ocean eutrophic - thick with plankton, dark, and hypoxic at depth. Adding iron would likely encourage more phytoplankton- worsening the problem. A On 20 September 2015 at 08:53, Schuiling, R.D.
