General description

Urea-15N2 enriched with 15N isotope.

Application

Urea-15N2 is used
  • In agriculture research as a technique to determine uptake or denitrification and leaching losses of native soil N via the “added N interaction".
  • In horticulture, massive labeling of trees to ascertain that N originating from 15N leaf labeling.

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.
