General description

Urea-15N2 a stable isotope compound enriched with 15N isotope.

Application

Urea-15N2 is used
  • In research related to agriculture as fertilizer to investigate crop uptake or denitrification and leaching losses of native soil N via the “added N interaction”.
  • To understand the dynamics of mineral fertilizer and organic-N in soil-plant systems.

The nitrogen (N) isotope method reveals that application of fertilizer N can increase crop uptake or denitrification and leaching losses of native soil N via the "added N interaction". However, there is currently little evidence of the impact of added

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
