A field experiment was designed with six treatments and four replicates with the main goal of ascertaining the impacts of sawdust and Bacterium BS1897 on soil properties, arsenic accumulation and yield of mung beans. The results showed that the Bacterium BS1897 inoculation combined with sawdust application, increased the soil nutrients and reduced arsenic content of mung bean. Arsenic content in stems (96.3 µg/kg) and in seeds (7.37 µg/kg) of the mung beans in treatment of 10-ton sawdust/ ha was lower than that of the control by 24.2% and 41.0%, respectively. The Bacterium BS1897–sawdust treatment increased pH, OM, total N, available P, exchangeable K and CEC in the soil, and the mung bean Yield in both sawdust application and Bacterium BS1897 inoculation was higher than that of the control treatment by 17.5% in sawdust addition group and 6.39% in Bacterium BS1897 group, respectively. The application of The Bacterium BS1897–sawdust reduced the uptake of arsenic and increased the soil fertility and yield of the mung beans. The greatest results were obtained from use of 10 ton sawdust/ha + 40 kg N+60 kg P + 60 kg K per ha and Bacterium BS1897.
