WebNitrogen is the most commonly limiting nutrient in plants. Legumes use nitrogen fixing bacteria, specifically symbiotic rhizobia bacteria, within their root nodules to counter the limitation. Rhizobia bacteria convert nitrogen gas (N 2) to ammonia (NH 3) in a process called nitrogen fixation. WebDec 28, 2024 · Plants can also obtain nitrogen from naturally occurring soil bacteria that capture it from the atmosphere—a process called biological nitrogen fixation. Nitrogen in gaseous form (N 2) is abundant in air, but because the molecule is extremely stable, plants can’t use N 2 until it’s been broken down.
