%X The traditional oil-melt method and drying over digestion for 20minutes ,30 minutes and 40 minutes under 150 ℃ were employed to measure the organic carbon content in soil humus extracts. The results indicated that there was not significant difference between the drying over digestion for both 30 minutes and 40 minutes at 150 ℃ and the traditional oil-melt method. It was found that the correlation between traditional oil-melt method and digestion for 30 minutes at 150 ℃ in drying oven was more significant (Y=1.008 2 X +0.000 3,r=0.9992**). 150 ℃ drying oven digestion method has the advantages of easier operation, better reproducibility, no laboratory pollution, etc.
