论述磷肥按溶解性分类情况。根据不同磷肥的溶解性（水溶性、弱酸溶性和枸溶性）选择合适的溶剂、称量范围和溶解条件，测定其有效磷（水溶性磷和枸溶性磷总和）含量，才能得到准确的结果。
論述燐肥按溶解性分類情況。根據不同燐肥的溶解性（水溶性、弱痠溶性和枸溶性）選擇閤適的溶劑、稱量範圍和溶解條件，測定其有效燐（水溶性燐和枸溶性燐總和）含量，纔能得到準確的結果。

The classification of phosphate fertilizer based on solubility is discussed. According to the solubility （water-soluble, weak acid soluble and citric solubility） of different fertilizers, the suitable solvent, weighing range and solution conditions are chosen for the determination of available phosphorus with the accurate results.
