Low δ18O Values of Nitrate Produced from Nitrification in Temperate Forest Soils

Analyses of δ18O of nitrate (NO3 –) have been widely used in partitioning NO3 – sources. However the δ18O value of NO3 – produced from nitrification (microbial NO3 –) is commonly estimated using the δ18O of environmental water and molecular oxygen in a 2:1 ratio. Here our laboratory incubation of ni...
