Abstract: The sensory, the physical, chemical and microbial evaluated indexes of pit mud for ten pits were measured including moisture, humus, available phosphorus, ammonia nitrogen, pH, total number of bacterial, the number of Bacillus and calcium. Then, the obtained value of sensory index was added with the physical, chemical and microbial evaluated indexes and thus the total score of evaluated indexes for each pit mud was obtained. The results showed that the total scores for No.6 and No.2 were maximal as 97.5 and 96.5 respectively which were with high quality; while the total scores for No.1 and No.9 were 23 and 27 with poor quality; and other samples of pit mud were with general quality. The results were basically the same as the single results of the sensory evaluation, or the physical, chemical and microbiological indexes. The experiments demonstrated that the detection of the indexes could contribute to the following corrective measures in production.
