This study examined the effects of molybdenum (Mo) and boron (B) on the rhizosphere microorganisms and the soil enzyme activities of soybean. The soybeans were treated with seven different Mo and B supplements (control: without Mo and B) Mo1 (0.0185 g kg-1), B1 (0.08 g kg-1), Mo1 + B1 (0.0185 ? 0.08 g kg-1), Mo2 (0.185 g kg-1), B2 (0.3 g kg-1) and Mo2 ? B2 (0.185 + 0.3 g kg-1) throughout the plants’ four growth stages. The results showed that Mo, B, and combined Mo and B treatments increased the soil microbial populations, stimulated the rhizosphere metabolisms, and improved the soil enzyme activities. These stimulatory effects varied in intensity among the treatment groups. The Mo and B combination treatments were more beneficial for the soybean rhizosphere soil than that of Mo-only or the B-only treatments, which suggests that the two elements have complementary functions in the biological processes of the soybean rhizosphere.
