According to GB/T 8572-2010 method,the determination of nitrogen content in compound fertilizer was analyzed by distillation titration,the mathematical model of nitrogen content was established and the main source of uncertainty was analyzed. Through the analysis of each component,synthetic standard uncertainty and expanded uncertainty were calculated. The results showed that the expanded uncertainty was 0.07%,and the determination results of nitrogen content was(10.29±0.07)%,k value was 2.
