What are inoculant Groups, which is the right one for my legume species?
29 JulBy atadmin
Legumes species require specific bacterial strains in order to interact effectively. Collectively nitrogen‐fixing bacteria are known as Rhizobium. Commercially in Australia the different strains of Rhizobium are identified and can be matched to their host legume by their inoculant group. E.g. Group G is for Lupins, another example, Group AL is the correct strain for Lucerne.
In some instances one inoculant Group is compatible with more than one legume species e.g. Group G can be used for both Lupin & Serradella. Also there are instances where one legume species can be inoculated by two different Groups as is the case with field peas where Group F and Group E are both compatible.
The basic table below aligns inoculant Groups to crop and forage legumes commonly grown in Australia. For a broader more expansive table see one of our inoculant Group Charts on our From the Field page.
