A seed-applied peanut inoculant formulated from native Bradyrhizobium and Rhizobium isolates (AM 01, AM 07) recovered from São Paulo and Rio de Janeiro soils, offering locally adapted nitrogen fixation plus phosphate solubilization where the standard commercial strain is genetically mismatched to native rhizobia.
