The application of manures for fertilization will influence the composition of phosphorus (P) species in the soil profile and the extent of dissolved P leaching to surface waters. Spatial and temporal changes in the P species composition of poultry-manure-amended soil were assessed at two soil column depths (0–5, 10–15cm) during 10weeks of leaching. Leachate P was primarily composed of dissolved fractions...
The technique of 31P-NMR spectroscopy has done more to advance the knowledge of organic P forms in environmental samples than any other method. Early 31P-NMR work limited identification to peaks that were clearly separated, such as orthophosphate and pyrophosphate, grouping the remaining peaks into broad categories such as orthophosphate monoesters and orthophosphate diesters. Advances in 31P-NMR...
Phosphorus (P) forms determined by 31P nuclear magnetic resonance spectroscopy (31P-NMR) are compositional data (i.e., parts of some whole bounded between 0 and the unit of measurement). Because compositional data are intrinsically related to each other within a closed pre-defined compositional space, a simple log transformation, variable by variable, or any other transformation of the compositional...
