Phosphorus (P) is essential for life, but most of the global surface ocean is P depleted, which
can limit marine productivity and affect ecosystem structure. Over recent decades, a wealth …

Although most organic matter (OM) in soil is mineralized by microorganisms, the
nonmicrobial processes, eg, Fenton reactions and photo-degradation, strongly contribute to …

Many physical, chemical, and biological processes in freshwater ecosystems mobilize the
nutrient phosphorus (P) from sediments, which in turn may contribute to the formation of …

This chapter presents an overview of the chemical nature of soil organic phosphorus (P) and
its role in determining the dynamics, availability, and mobility of soil P in agroecosystems. It …

Lowland river–floodplain systems are characterized by a high degree of variability in both
the frequency and period of inundation of various parts of the floodplain. Such variation …

This paper seeks a perspective on the forms of phosphorus which promote aquatic
eutrophication, with the particular quest of establishing their sources. A short background …

Life is believed to have originated on Earth∼ 4.4–3.5 Ga ago, via processes in which
organic compounds supplied by the environment self-organized, in some geochemical …

Phosphorus is an essential macronutrient for all marine microorganisms. Dissolved organic
phosphorus (DOP) is an integral, dynamic part of the marine organic matter pool and of the …

Information on the chemical forms of organic phosphorus (P) in soil waters is fundamental to
understanding the dynamics of soil organic P and its potential for transfer from soils to …

Organic phosphorus is involved in almost every biological process. Organic forms of
phosphorus often dominate in soils and aquatic systems and many organisms possess …
