土壤总磷包括有机磷和无机磷,其中无机磷能够直接被植物利用。土壤有机磷经过矿化分解而转化为无机磷。同时测定土壤总磷、有机磷和无机磷,可以全面反映土壤磷营养状况。 测定原理:利用钼蓝法定磷。取一份土样,通过浸提法测定土壤无机磷含量;另外取一份土样,经高温灼烧后,土壤有机磷转化为无机磷,测得土壤总磷含量;总磷含量减去无机磷含量,即可计算出有机磷含量。
Total soil phosphorus includes organic phosphorus and inorganic phosphorus, among which inorganic phosphorus can be directly utilized by plants. Soil organic phosphorus is converted into inorganic phosphorus through mineralization and decomposition. Simultaneous determination of total phosphorus, organic phosphorus, and inorganic phosphorus in soil can comprehensively reflect the soil phosphorus nutritional status. Determination principle: The molybdenum blue method is used for phosphorus determination. One soil sample is taken to determine the soil inorganic phosphorus content by extraction method; another soil sample is taken and subjected to high-temperature ashing to convert soil organic phosphorus into inorganic phosphorus, thereby obtaining the total soil phosphorus content. The organic phosphorus content can then be calculated by subtracting the inorganic phosphorus content from the total phosphorus content.
