Effect of nitrate concentration in lake water on phosphate release from the sediment

TLDR
In this article, the effect of oxidized nitrogen (mainly nitrate) in preventing phosphate release from the sediment demonstrates the ability of oxidised nitrogen to buffer the redox potential of the surface sediment at a level high enough to prevent a release of phosphate.About:

Exchange of phosphorus across the sediment-water interface
TL;DR: In this paper, the principles of phosphorus retention and phosphorus release at the sediment-water interface in lakes are reviewed and new results and hypotheses are discussed in relation to older models of phosphorus exchange between sediments and water.

Iron:phosphorus ratio in surface sediment as an indicator of phosphate release from aerobic sediments in shallow lakes
TL;DR: Analysis of Danish lakes showed that both mean winter and mean summer concentrations of lake water total phosphorus in the trophogenic zone correlated negatively with the total iron to total phosphorus ratio (Fe:P) in surface sediments.

Lake restoration by reducing external phosphorus loading: the influence of sediment phosphorus release
TL;DR: Improvements in the condition of highly eutrophic lakes require very large reductions in external phosphorus loading, whereas in mildly enriched lakes moderate changes in the supply of phosphorus have noticeable effects on phytoplankton biomass.

Enhancement of dissolved phosphorus release from sediment to lake water by Microcystis blooms--an enclosure experiment in a hyper-eutrophic, subtropical Chinese lake.
TL;DR: The results indicate that Microcystis blooms induced massive release of P from the sediment, perhaps mediated by high pH caused by intense algal photosynthesis, and/or depressed concentrations of nitrate nitrogen (NO3-N).
Book ChapterDOI
Internal phosphorus loading in shallow Danish lakes
TL;DR: It is concluded that internal loading of shallow eutrophic lakes may have a considerable and persistent impact on summer TP after reduced external loading.

A modified single solution method for the determination of phosphate in natural waters
J. Murphy,J.P. Riley +1 more
TL;DR: In this article, a single solution reagent was described for the determination of phosphorus in sea water, which consists of an acidified solution of ammonium molybdate containing ascorbic acid and a small amount of antimony.
