Purpose Nitrogen (N) fertilizer application in agricultural soil is a primary anthropogenic nitrous oxide (N2O) source. Currently, the effect of the N fertilizer type on N2O emissions from upland soil has been rarely reported. To this end, impacts of var...

The biological pattern of plants’ nitrous oxide (N2O) generation is not well understood because plant cells cannot form N2O from nitric oxide (NO) reduction. Hypothetically, we consider that plant-endophytic co-denitrification is potentially capabl...
