Abstract:

In the past several decades, the development of nitrogen (N) stable isotope techniques has improved the understanding of N cycling in terrestrial ecosystems. This review briefly introduced the history of N stable isotope techniques in studying N cycling in terrestrial ecosystems and summarized typical studies focusing on different aspects of ecosystem N cycling in recent years, including using 1) 15N natural abundance to identify plant N sources, indicate N status of ecosystems, and quantify N transformation rates; 2) 15N enriched tracers to study N fates, redistribution and gaseous loss from ecosystems. In the end, this review points out challenges and future applications of N stable isotope techniques on studying N cycling in terrestrial ecosystems.

Key words: nitrogen stable isotope technique, natural abundance technique, 15N labelling technique
