Abstract
⺠Four experimental cropping systems differed two-fold in annual C inputs. ⺠A freeze-thaw induced flush in respiration from intact soil ceased within 48 h. ⺠Nitrous oxide emissions were highest from the system with lowest annual C input. ⺠Denitrification was the main source of N2O, as indicated by gaseous 15N losses. ⺠Gas diffusivity was a main driver of N2O, but interacted with cropping system.
