nitrogen-cycle

2 articles

The nitrogen cycle describes how nitrogen moves through the atmosphere, soil, and living organisms via processes like fixation, ammonification, nitrification, and denitrification, transforming it into forms plants can absorb. Since nitrogen is a key building block of chlorophyll, amino acids, and nucleic acids, plant growth and productivity are directly tied to how efficiently this element is cycled and made available in the soil. Understanding these pathways helps researchers improve crop yields, manage fertilizer use, and study plant-microbe symbioses such as those with nitrogen-fixing bacteria.
