Species vs. strains - what’s the difference?

Because nitrogen inoculants work by infecting a plant root, each pulse crop associates with a different Rhizobia species. For example, pea and lentil will only form nodules when inoculated with Rhizobium leguminosarum; lucerne and sweetclover when inoculated with Sinorhizobium meliloti.

The Natural Rhizobia Program co-ordinates and conducts on-going research to find the best strains for each legume crop in Australia. These are then listed as recommended by inoculant group.

Legume Crops Inoculant Species Inoculant Group
Pea Rhizobium leguminosarum Group E
Lentil, Faba Bean Rhizobium leguminosarum Group F
Chickpea Mesorhizobium ciceri Group N
