Fig. 1: Results from a data synthesis on the effect of experimental duration on EFs.
From: Legacy effects cause systematic underestimation of N2O emission factors
a the EFs of long-term and short-term N fertilization and their difference. b the difference in background N2O emissions (ΔE0) and N2O emissions under N fertilization (ΔE) between long-term and short-term N fertilization. c ΔEF under different durations (Δyr). EFs, N2O emission factors; ΔEF, the difference in EFs between long-term and short-term N fertilization. The error bars represent 95% confidence intervals. Source data are provided as a Source Data file.
