从大量土样中提取稳定性有机磷的５组ｐＨ值范围的沉淀物，将它们返加到土壤中后的矿化速率的差异表明，划分中稳性与高稳性土壤有机磷比较合理的ｐＨ值是３．００。
The differences in the mineralization rates of 5 sediments from a large amount of soil samples for the extraction of stable organophosphorus in the pH range show that it is reasonable to classify the stable and highly stable soil organophosphates The pH is 3.00.
