UK scientists found one strain locked nitrogen in the soil, while another released a potent greenhouse gas.
The findings came to light after the researchers sequenced Bradyrhizobium, one of the most active and abundant groups of soil bacteria.
The findings were published recently in the journal Scientific Reports.
The team from the University of Reading and Rothamsted Research were the first to sequence the genome of Bradyrhizobium from European soils, allowing the scientists to compare strains of the bacteria from different parts of the world.
They collect strains of bacteria from various soils in a long-term experiment at Rothamsted Research, from plots that had been maintained as grassland or ploughed bare soil for the past six decades.
