High N2O emissions have been observed in semi-arid grasslands, especially during freeze/thaw periods, when denitrification might be the main process of N2O production. However, there have been few denitrification studies in semi-arid grassland. This study was designed to determine the denitrifica...

In situ field measurements as well as targeted laboratory studies have shown that freeze–thaw cycles (FTCs) affect soil trace gas fluxes. However, most of past laboratory studies adjusted soil moisture before soil freezing, thereby neglecting that snow cover or water from melting snow may modify ...
