Soil organic nitrogen priming to nitrous oxide: A synthesis
The priming effect (PE) is the short-term increase or decrease in the rate of soil organic matter mineralization in response to a stimulus, such as the addition of carbon (C) and/or nitrogen (N) to the soil. Literature has generally framed the PE in terms of CO2 evolved from soil organic carbon mine...

The priming effect (PE) is the short-term increase or decrease in the rate of soil organic matter mineralization in response to a stimulus, such as the addition of carbon (C) and/or nitrogen (N) to the soil. Literature has generally framed the PE in terms of CO2 evolved from soil organic carbon mineralization, but fewer publications have focused on how the PE affects the soil N cycle and nitrous oxide (N2O) production from soil organic N mineralization (SOM-N), despite the potency of N2O as a greenhouse gas and ability to destroy stratospheric ozone. This review summarizes our current understanding of how the PE can alter the rates of SOM-N mineralization and subsequently amplify, diminish, or maintain N2O production in and release from soils, henceforth referred to as N2O priming. Additionally, the concept of process priming, the differential augmentation of N2O-producing processes (e.g. priming of nitrification) is introduced. Diverse results across studies suggest that the mechanisms of N2O priming cannot be fully explained by a single hypothesis, and it is currently unclear how significant the contribution of N2O priming to net N2O emissions is, but a preliminary estimate suggests that N2O emissions resulting from priming mechanisms can range from -39 – 76% following C and N amendments compared to a control.
