Freshwater wetland ecosystems do not effectively conserve phosphorus in the way that terrestrial ecosystems do. The phosphorus retention capacity varies greatly among bogs, fens, and swamps and is concomitant with the amorphous acid oxalate-extractable aluminum and iron content in the soil. However, the phosphorus adsorption potential in wetland ecosystems may be predicted solely from the extractable aluminum content of the soil. Wetlands tested as wastewater filtration systems became phosphorus-saturated in a few years, with the export of excessive quantities of phosphate.
淡水湿地生态系统并不能像陆地生态系统那样有效地保存磷。沼泽、湿地和沼泽地的磷保持能力差异很大，与土壤中无定形酸草酸盐可提取的铝和铁含量相关。然而，湿地生态系统的磷吸附能力可以仅根据土壤中可提取的铝含量来预测。作为废水过滤系统的湿地在几年内就达到了磷饱和状态，磷酸盐的排放量过大。
