摘  要：
In order to analyze the proficiency test results of content determination of total nitrogen, available phosphorus, potassium oxide and chloride ion in compound fertilizer, according to Compound Fertilizer(Compound Fertilizer)(GB 15063—2009) and the work instruction of proficiency test of determination of total nitrogen, available phosphorus, potassium oxide and chloride ion in compound fertilizer, two test samples were determined. The results showed that in sample 2019-A16-025, the content of total nitrogen, available phosphorus, potassium oxide and chloride ion was 17.34%, 17.64%, 13.53% and 10.43%, respectively; in sample 2019-A16-693, the content of total nitrogen,available phosphorus, potassium oxide and chloride ion was 17.12%, 10.16%, 15.50% and 12.23%, respectively. The determination results of two samples were satisfactory and illustrated that the laboratory had the detection ability of total nitrogen, available phosphorus, potassium oxide and chloride ion in compound fertilizer.
