Balancing the nitrogen (N) budgets of agricultural systems is essential for sustaining yields at lower environmental costs. However, it is still rare to find reports on the total N budgets of agricultural systems including all N fluxes in the literature. Here, we conducted a comprehensive study o...

Aims A 3-year field experiment (October 2004–October 2007) was conducted to quantify N2O fluxes and determine the regulating factors from rain-fed, N fertilized wheat-maize rotation in the Sichuan Basin, China. Methods Static chamber-GC techniques were used to measure soil N2O fluxes in three tre...

Fertilizer nitrogen (N) application has been shown to impact both methane (CH4) and nitrous oxide (N2O) emissions from rice-based crop systems, yet the responses of CH4 and N2O fluxes to N fertilizer applications in subtropical rice–rapeseed rotation systems are not well documented. A three-year ...
