原始语种摘要: Modified Hedley fraction method was used to study the forms and profile distribution in the tidal river network region subjected to rapid deposition and hydrologic disturbance in the Yellow River Delta (YRD) estuary, eastern China. The results showed that the total P ( P t ) ranged from 612.1 to 657.8 mg kg−1. Dilute HCl extractable inorganic P ( P i ) was the predominant form in all profiles, both as absolute values and as a percentage of total extracted P i . The NaOH extractable organic P ( P o ) was the predominant form of total extracted P o , while Bicarb- P i and C.HCl- P o were the lowest fractions of total extracted P i and P o in all the P forms. The Resin-P concentrations were high in the top soil layer and decreased with depth. The Pearson correlation matrix...
