This paper reviews the abiotic processes that could lead to the stabilization of organic phosphorus in soils and the aquatic environment. The role of adsorption to soil minerals, complexation reactions, precipitation with polyvalent cations and the incorporation of organic phosphorus into humic substances in stabilizing organic phosphorus are examined in particular. The effects of soil solution chemistry on these reactions, as well as the effects of these reactions on the environment are also discussed.
This paper specifically focuses on the importance of organic phosphorus as a source of phosphorus for plant nutrition. In particular, the importance of rhizosphere phosphatase activity and its role in hydrolysing organic phosphorus in soil is considered. The bioavailability and utilization of organic phosphorus by plants as well as in the soil are also discussed.
This paper reviews the use of 31P nuclear magnetic resonance (NMR) spectroscopy for soil, water and other environmental samples (i.e., forest floor material, alkaline agricultural soil, marine sediment, sewage sludge and humic acid). After a brief overview of the principles of NMR spectroscopy, the requirements for a successful NMR experiment are described. A literature on 31P NMR spectroscopy in soils and environmental samples is also reviewed, followed by suggestions for future research needs.
This paper discusses the enzymatic hydrolysis of organic phosphorus with reference to the classical inorganic and organic compartmental analysis of phosphorus compounds in ecosystems. Also discussed are: the potential use of soil organic phosphorus by plants and microorganisms; properties of phosphohydrolases; inhibitors and activators; phosphohydrolase activity in soil; rhizosphere and mycorrhizal aspects of phosphohydrolase activity; and the regulation of the phosphohydrolase activity in the rhizosphere.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
