摘要：

The objective of this study was to investigate the applicability of selective extraction methods in combination with solution phosphorus-31 (P-31) nuclear magnetic resonance (NMR) for the determination of organic phosphorus (P-o) species in soil. Inositol hexakisphosphates (IHP) and glucose 6-phosphate (GP) were identified in the soil. IHP adsorbed to both soil organic matter (SOM) and short-range order (SRO) minerals, whereas GP adsorbed only to SOM. These results suggest that P-o hosting phases are different depending on Po species.
