Phosphorus Along the Soil-Freshwater-Ocean Continuum

Phosphorus (P) is essential for life but often in short supply in freshwater and marine ecosystems where its availability may control growth and thus biological productivity. Yet nonpoint source P transfer from land to water remains a contributor to eutrophication and algal blooms in many freshwater aquatic systems worldwide. Despite being a research priority for several decades, the cycling of P in aquatic systems is still poorly understood, although there have been promising advances in methodology in recent years.
This Research Topic aims to bring together soil, freshwater and marine scientists with original research on P cycling in terrestrial, lacustrine, wetland and coastal and open ocean environments. We particularly welcome studies focusing on P movement from terrestrial to freshwater and marine environments with direct links to aquatic eutrophication, and on original approaches to better understand P speciation, bioavailability (inorganic and organic forms, different oxidation states) and biogeochemistry in a wide range of aquatic ecosystems.
