Short summary
We examined the spatial variability in N2O emissions from a tea field in a wet season using 147 static chambers. The N2O fluxes for a 30min snapshot ranged from -1.73 to 1659.11 g N ha-1 d-1 (average flux of 102.24 g N ha-1 d-1). Cokriging with NH4Nt and NO3Nt as covariables (r=0.74 and RMSE=1.18) outperformed ordinary kriging (r=0.18 and RMSE=1.74), regression kriging with the sample position as a predictor (r=0.49 and RMSE=1.55) and cokriging with SOCt as a covariable (r=0.58 and RMSE=1.44).
