Nitrogen-fixing plants are special types of plants that can convert atmospheric nitrogen into a form that is usable by other plants. This process occurs through a symbiotic relationship with certain bacteria, often found in the roots of these plants. Common examples include legumes like clover, peas, and soybeans. These plants play a crucial role in agriculture and ecosystems by enriching the soil with nitrogen, which is an essential nutrient for plant growth. By planting nitrogen-fixing plants, farmers can improve soil fertility naturally, reducing the need for chemical fertilizers and promoting sustainable farming practices.
