Identifying And Responding To Soybean Inoculation Failures

February 7, 2014 | Posted in Nutrient Management

Source: By Mike Staton, Michigan State University Extension

Soybeans obtain up to 70% of their total nitrogen requirement from biological nitrogen fixation conducted by Rhizobia bacteria colonies (nodules) living on soybean roots. If the nodules fail to form, the plants will become deficient in nitrogen and significant yield reductions can occur.

Crop Insights: Nitrogen Fertilizer for Soybean?

November 15, 2013 | Posted in Nutrient Management

Source: John P. Schmidt, DuPont Pioneer Research Scientist

Unlike corn, wheat and most other row crops grown in North America, soybean is able to obtain its own nitrogen (N) through the process of N fixation. N fixation is achieved through an intricate biological relationship between soybean and a particular species of soil bacteria, Bradyrhizobium japonicum. The bacteria obtain sugars from soybean to use as their energy source, and soybean obtains N from the bacteria.
