AB  - Limited information is available on the changes of phosphorus speciation of soil in Tibet of China. A soil sample was collected from Tibet of China. Phosphorus availability from soil is influenced by its chemical speciation. The major objective of this study was to investigate the P speciation in the soil of Tibet of China treated by a Hydrothermal Method in the solution of distilled water, NaHCO<SUB>3</SUB> (0.5 M), NaOH (0.1M) and HCl (0.1 M) at 180&deg;C for 12 h. The obtained samples were characterized by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). Results show that the obtained samples were high crystallinity with decreasing particle size after hydrothermal treatment compared with that treated by Traditional Sequential Extractable Method. A possible reaction mechanism was proposed and discussed.
