Abstract

Why is it that we see soybean yield responses from inoculating with Bradyrhizobia japonicum in some cases but not others?

This publication explains how to distinguish which fields will likely respond to inoculation with B. japonicum from those that will not. Fields are designated as either "new" or "old" based on how often soybean is grown. This designation is one criterion among many in deciding when to inoculate. In general, research trials across multiple locations in Nebraska have shown no yield advantage to re-inoculation.
