Acid tolerant Rhizobium strains contribute to increasing the yield and profitability of common bean in tropical soils

Symbiosis of common bean with nitrogen-fixing bacteria can lead to a reduction in production costs and in environmental impacts. Considering the diversity of soils and climates, it is important to validate bacterial strains under different conditions to consolidate their recommendation as inoculants...
