Oxalic acid loading substantially stimulated soil P release from A1 horizon, showing a linear relationship; but its effect on B horizon soil was relatively negligible, especially at low oxalic acid concentrations mmol L^(-1. Oxalate solutions 0.5~20.0 mmol L^(-1 oxalic acid adjusted to pH 5.16 with 10.0 mmol L^(-1) NaOH had a much higher (1.51~2.98 times) soil-P-release effect than oxalic acid solution the same in oxalate concentration. Therefore, the mechanism of oxalic acid/oxalate triggering release of soil phosphorus is assumed to be dominated by ligand-exchange or complexing reactions of oxalate anionC2O(superscript 2- subscript 4 but not simply acid-dissolving effect. The effect of oxalate anion on soil phosphorus release was found to be somewhat cumulative, i.e. the amount of P released was primarily controlled by the cumulative oxalate loading rate, relatively independent of the manner of oxalate addition (one-time or sequential).

结果表明，草酸能显著促进暗棕壤A层磷的释放，土壤磷溶出量随草酸溶液浓度升高而线性增加；但对B层土壤磷的释放效应相对较弱，草酸浓度低於5mmolL^(-1)时B层磷的释放不明显。pH5.16草酸钠溶液比相同浓度的草酸溶液具有更高的解磷效率，在设置二者浓度为0.5~20.0mmolL^(-1)时，前者的解磷量是后者的1.51~2.98倍，推断草酸盐溶液或凋落物淋洗液中草酸类物质促进暗棕壤磷释放的主要机理在於草酸阴离子C2O(上标 2-下标 4配位反应。
