WebStable N isotopes are used to examine the source, flow and fate of N at scales ranging from greenhouse pots to landscapes. There are two main approaches: the 15 N-enriched method applies an artificially enriched source of 15 N and the 15 N natural abundance (δ 15 N) method uses natural 15 N differences between N sources and sinks..
