Question

Quizplus · Accepted Answer

Legumes have a unique ability to form a symbiotic relationship with nitrogen-fixing bacteria in their roots, which allows them to convert atmospheric nitrogen into a form that plants can use. This increases the soil's fertility and reduces the need for additional nitrogen fertilizer. Growing legumes in rotation with primary crops like corn, wheat, or soybeans, can improve the soil quality, and result in higher yields for both crops over time.
