Total nitrogen in organic fertilizers was determined by model AA3 continuous flow analyzer, and the results were compared with those by NY 525 - 2012. It showed that there was no significant difference between the two methods. Its coeffi-cient of correlation reached 1. 000 0 and the average recovery of spiked standard was at 98. 40% ~ 102. 8% .
