AbstractThis 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.
