The process through which atmospheric nitrogen (N₂) is converted into nitrates (NO₃⁻) by bacteria is known as nitrogen fixation. This biochemical process occurs primarily in the root nodules of leguminous plants, where certain bacteria, such as Rhizobium, play a crucial role. They convert nitrogen gas from the atmosphere into forms that plants can absorb and utilize for growth.
