Acid tolerant rhizobia improve nodulation of faba and broad bean.

Key points

• Inoculation of pulses is widely recommended, particularly where the pulse is sown into paddocks with acidic soils or, where the pulse or another in the same inoculation group has not been sown for a number of years.
• A new high-performing rhizobia strain for Group F (faba and broad bean inoculant) with improved nitrogen fixation and acid soil tolerance will be available for the 2024 season.
• The new strain (SRDI-969) will replace strain (WSM-1455)
• The new strain can provide optimal nodulation down to pHCa 5.0 and improved nodulation to pHCa 4.5.
