Seasonal variation in (a) daily soil temperature°C (0–10 cm), and water-filled pore space (WFPS %), and (b) daily changes in soil electrical conductivity (EC, dS/m) in the rice-wheat cropping system from 2012–2015.
Fig 3.
Seasonal variation of nitrous oxide (N2O) (μg m-2 h-1) emission fluxes from rice-wheat cropping systems in three annual cycles during the period of 2012–2015.
The error bars show standard errors of the mean (n = 3) and arrows indicate fertilizer application times.
