In some places, though, iron is the limiting nutrient.
In all experiments nitrogen was the limiting nutrient and was consumed after 5 days (data not shown).
This finding has important implications to downstream coastal estuaries, including Florida Bay, and to nearshore coastal ocean ecosystems, such as coral reefs, where N is the limiting nutrient.
Along the same lines, the clear relationships between soil P status and aboveground biomass in the HK Kalke experiment (Fig. 2) was validation that P was the limiting nutrient in the experiment.
This phenomenon reflected that phosphate was the limiting nutrient for the cell growth and feeding potassium dihydrogen phosphate in the early phase of fermentation could alleviate the phosphate limitation.
We examined the relative importance of the whale pump in the Gulf of Maine, a partially isolated, highly productive basin in the western North Atlantic Ocean where nitrogen is generally considered to be the limiting nutrient for phytoplankton growth [17].
In many locales in coastal oceans, nitrogen has been demonstrated to be the limiting nutrient, with large-scale circulation patterns (such as upwelling) being the primary determinant of coastal productivity.
It is assumed, thus, that phosphate is the limiting nutrient, especially in the eastern basin [ Siokou-Frangou et al., 2010].
The eastern Levantine basin is mainly limited by phosphate, while nitrate is the limiting nutrient in the western basin [ Krom et al., 2004].
Nitrogen can be the limiting nutrient in coastal ecosystems [ 86] and under this situation, nitrogen fixing cyanobacteria may be favored and gain in growth and reproductive success.
