Populations of Bradyrhizobium japonicum in Fields Cropped with Soybean-Rice Rotations1

摘要: The population density of Bradyrhizobium japonicum in soil, before planting, largely determines the potential yield increase soybean (Glycine max L. Merrill) due to inoculation. Soybean is cultured rotation with rice (Oryza saliva L.) paddy belt southern USA. Nineteen fields were sampled determine influence culture on B. japonicum. Populations following approximately 1 X 10 bradyrhizobia g soil. Growing after did not reduce bradyrhizobia. Apparently able survive conditions saturated soil for several months.
