What are legume inoculants?
29 JulBy atadmin
Legume inoculants are the group of products applied in-furrow or on seed to enhance and promote legume-rhizobium symbiosis. Root nodule symbiosis is a mutually beneficial biological process for both the treated legume crop or forage species and the applied nitrogen‐fixing bacteria (inoculant).The applied nitrogen‐fixing bacteria, once established as root nodule colonies, are able to capture and convert atmospheric nitrogen into a form that is directly available for plant growth while the legume plant supplies nutrients to the bacteria.
Legume inoculants are living cultures of nitrogen‐fixing bacteria and as such are perishable and care should be taken to observe manufacturers’ storage and application directions to enhance product outcomes.
Legume inoculant products are available in different formulations or types. Each formulation has a range of benefits and constraints that should be considered to best meet the end-user’s needs. see PRODUCT RANGE
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 Gin for Lupins, another example,Group AL is the correct strain for Lucerne.
