Brief Project Summary:

Inoculation of soybean with Bradyrhizobium japonicum is essential to the fixation of atmospheric nitrogen and conversion to nitrate nitrogen. This process allows soybeans to use nitrogen from the air and negates the need for fertilizer nitrogen. Historically, soybean fields that have grown nodulated soybeans in the past three to five years do not require inoculation. However, there are many suggestions and testimonials that inoculant each year on soybean increases yield. This study evaluates yearly inoculation of both full season and double crop soybeans to determine if yields increase.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
