摘要：

Several methods for the determination of soil phosphorus (P) in acidic forest soils were examined. The Parkinson and Alien digestion method removed more total P than did the ignition method, especially with mineral soils. There were problems with both the Saunders and Williams ignition method and the Bowman and Moir extraction protocol for organic P determination. The problems were more pronounced when used on organic soil samples The Bray P1 was better than the Mehlich 3 method for measuring available P in mineral soils.
