Nitrate labeled with 13N (13NO3 -) was produced in a cyclotron by the 16O(p, α) 13N reaction with protons having energies of 14.5 million electron volts. The 13NO3- was used as a tracer for direct quantitative measurements of denitrification rates in soils from flooded rice fields. The 13N technique provides a new tracer method for the measurement of denitrification rates in natural systems over short time intervals, without changing the concentration of NO3- in the system.
