Responses of N<sub>2</sub>O and CH<sub>4</sub> fluxes to fertilizer nitrogen addition rates in an irrigated wheat-maize cropping system in northern China
Model and field studies generally posit that when the application rates of nitrogen fertilizer exceed crop needs, nitrous oxide (N<sub>2</sub>O) emissions will increase nonlinearly, though linear responses are also extensively reported by field studies. We conducted year-round measuremen...
