Nitrogen fixation is a process where nitrogen gas from the atmosphere is converted into a form that can be used by plants. This process is mainly carried out by nitrogen-fixing bacteria found in the soil. These bacteria have the ability to convert atmospheric nitrogen into ammonia through a series of enzymatic reactions. The ammonia produced is then converted into ammonium ions, which can be absorbed by plants to use as a source of nitrogen for their growth and development. This process is essential in replenishing the soil with nitrogen, which is a crucial nutrient for plant growth.
