• Advances in Host Plant and Rhizobium Genomics to Enhance Symbiotic Nitrogen Fixation in Grain Legumes (2015, background): “Furthermore, breeding in low N soils in South America has resulted in hundreds of soybean commercial cultivars with high SNF capacity.”
• Global inputs of biological nitrogen fixation in agricultural systems (2008, background): “…at 80%, reflecting the widespread use of rhizobial inoculants, the high N demand of the crops (about 300 kg N/ha) coupled with low inputs of fertiliser N, and the high proportion of the crops that are no-tilled (Hungria and Vargas 2000; Hungria et al. 2005, 2006; Alves et al. 2003; FAOSTAT).”

• Reconciling biodiversity conservation and food security: scientific challenges for a new agriculture (2010, background): “For example, soybean production in Brazil almost entirely relies on biological nitrogen fixation instead of N fertilizers, which is the result of selection and subsequent mass inoculation of efficient strains of N2-fixing bacteria [28].”
• Co-Inoculation of Soybean with Bradyrhizobium and Azospirillum Promotes Early Nodulation (2015, methodology): “At the beginning of the experiment, twenty soil subsamples (0 - 20 cm) were taken to evaluate soil chemical properties and soil granulometry, as described before [29].”
• Nitrogen fixation with the soybean crop in Brazil: Compatibility between seed treatment with fungicides and bradyrhizobial inoculants (2009, background): “…plant and the bacterial strains have been reported for the soybean crop in Brazil, but any factor which may reduce the population of inoculated bradyrhizobia on the seed surface will have direct effects on the biological N2 fixation process (Hungria and Vargas, 2000; Hungria et al., 2005, 2006a).”
