Why does legume growth often improve when Bradyrhizobium bacteria are present in soil?

💡 Explanation

Legumes benefit from Bradyrhizobium because of nitrogen fixation, a symbiotic process where bacteria convert atmospheric nitrogen into ammonia, a usable form for the plant. Therefore, enhanced nitrogen availability promotes growth, rather than proton gradients, cellulose degradation, or lipid synthesis impacting it directly.
