Nitrogen-15 tracing

Nitrogen-15 tracing refers to a technique used in various fields, including biology, ecology, and environmental science, where the stable isotope nitrogen-15 (N-15) is tracked to study nitrogen cycling, plant nutrition, and ecosystem dynamics. Nitrogen-15 is a naturally occurring isotope of nitrogen, making up about 0.37% of all nitrogen in nature, while the more common isotope, nitrogen-14 (N-14), accounts for the majority.
