Nitrogen in grains primarily comes from the soil, where plants absorb nitrogen in the form of nitrates and ammonium through their root system. Some grains, like legumes, can also fix nitrogen from the air through a symbiotic relationship with nitrogen-fixing bacteria in their root nodules. Farmers may supplement nitrogen levels in the soil through fertilizers to ensure sufficient supply for optimal grain growth.
