Stable Isotopes in Agriculture

Tracer techniques using isotopic N have been employed since the 1940s to investigate such topics as N transformations and cycling in agricultural and other soils, N sources for crop uptake, the fate and behavior of fertilizer N applied to soils, the nature and extent of soil and fertilizer losses, and fertilizer N uptake efficiency.
