Use of quality legume inoculants to get the most from nitrogen fixation

Abstract

Key points »» Rhizobia symbiotically fix close to three million tonnes of nitrogen a year worth $4 billion. »» The Australian Inoculants Research Group (AIRG) and its predecessors have controlled and maintained the quality of legume inoculants through collaboration with industry, universities and R&D bodies for close to 60 years. »» A symbol of inoculant quality assessment by an independent laboratory is the display of the green tick logo. »» There are different inoculant groups specific for different legumes. »» Correct storage is important to maintain high numbers of rhizobia in the inoculants. »» The AIRG continues to monitor the quality of legume inoculants at different points in the supply chain and works closely with the manufacturers to ensure that Australia’s growers have ongoing access to efficacious products.
