From: Microplastic fibers affect dynamics and intensity of CO2 and N2O fluxes from soil differently
Relationship between (a,b) ammonium content of the soil and cumulative N2O emission; (c,d) content of cold water extractable soil C and cumulative N2O emission; and (e,f) ammonium content of the soil and cumulative CO2 emission for the four different treatments for all treatment repetitions (n = 16; a,c,d) and treatment averages (AVG; n = 4; b,d,f). Error bars and gray shaded area (b,d,f) denote ±SD and confidence interval of the respective logarithmic (b,d) and linear function (f) fitted to the data (b: r2 = 0.70; d: r2 = 0.52; f: r2 = 0.55). Treatment combinations are indicated by different colors (red = no N; blue with N added) and symbols
