The contrast experiments of three methods for the determination of humus content in pit mud including oil bathing method, conden-sation reflux method, and digestion furnace method were carried out. And the experimental results were analyzed and compared by ANOVA. The analytic results suggested that, there was no significant difference in the determination results of the three methods. Among them, digestion furnace method had more accurate determination results and higher stability. Besides, it was economical, reliable, and simple to operate which could avoid some security risks in oil bathing method and the disadvantages such as long time consumption in condensation reflux.
