The utilization of inorganic and organic phosphorous compounds as nutrients by eukaryotic microalgae: a multidisciplinary perspective: part 1
TL;DR: This comprehensive literature review of the phosphorus nutrition and metabolism of eukaryotic microalgae deals sequentially with extracellular P-compounds available for algal utilization and growth and includes specific macroalgae in considering certain subtopics where such algae were better investigated and provided a good basis for comparison.

Sediment-based nutrition of submersed macrophytes
John W. Barko,R. Michael Smart +1 more
TL;DR: The capabilities of four species of submersed freshwater macrophytes to mobilize nitrogen, phosphorus and potassium from three different sediments were comparatively examined in relation to their requirements for these nutrients during a 10-week period of growth under controlled environmental conditions.

Review of robust measurement of phosphorus in river water: sampling, storage, fractionation and sensitivity
TL;DR: In this paper, a review of current knowledge on sampling, storage and analysis of phosphorus (P) in river waters is presented, which highlights the need to tailor analytical reagents and concentrations to take into account the characteristics of the sample matrix.

The Estimation of Phosphate and of Total Phosphorus in Sea Waters
TL;DR: The growth of bacteria and the physical adsorption of organic phosphorus compounds in solution on the walls of glass vessels used for storage of sea water have been investigated, and a method of prevention evolved, and procedures for the estimation of phosphate and total phosphorus are described.

A comparison of some methods for total phosphate analyses
TL;DR: In this article, five different methods have been tested on six solid and five liquid samples for total phosphorus analyses, and all the samples were readily oxidized by persulphate, and hydrogen peroxide methods.
