Nitrogen fixation
Nitrogen fixation is the process by which certain bacteria convert nitrogen gas from the atmosphere into ammonia, a form that plants can use to grow. This is vital because nitrogen is essential for plant life, but most plants cannot use atmospheric nitrogen directly. Some bacteria live in the roots of specific plants, like legumes, helping them absorb the converted nitrogen. This not only supports plant growth but also enriches the soil, making it healthier for other plants. Nitrogen fixation plays a crucial role in agriculture and ecosystems, helping maintain the balance of nutrients in the environment.

-
Nitrogen fixation is a natural process that converts atmospheric nitrogen, which plants cannot use, into a form they can absorb, like ammonia. Certain bacteria, found in the soil and in the roots of legumes (like beans and peas), carry out this transformation. This process is essential for plant growth because nitrogen is a key nutrient. In agriculture, nitrogen fixation enhances soil fertility, reducing the need for chemical fertilizers. Overall, it plays a critical role in the nitrogen cycle, supporting ecosystems and food production.

Nitrogen fixation is a natural process where nitrogen gas from the air is converted into a form that plants can use, such as ammonia. While the atmosphere is about 78% nitrogen, most plants cannot directly use it. Certain bacteria, often found in the roots of leguminous plants, perform this conversion. This process enriches the soil, making it more fertile and supporting plant growth. Nitrogen fixation is crucial for agriculture and the ecosystem, as it helps maintain the nitrogen cycle, which is essential for all living organisms.
