Why do legumes grow better in a nutrient poor soil than many other plants?

Legumes have a unique ability to form symbiotic relationships with nitrogen-fixing bacteria, such as Rhizobium, in their root nodules. This allows them to convert atmospheric nitrogen into a form that is usable for growth, compensating for nutrient-poor soil conditions. Additionally, legumes can enhance soil fertility through the process of nitrogen fixation, enriching the soil for future crops. This adaptation enables them to thrive where many other plants struggle.
