Plot showing the average a net CO₂ flux (mg C m⁻² h⁻¹) and b net CH₄ flux (mg C m⁻² h⁻¹) measured in light (light blue, lower panels) and dark (dark blue, upper panels) conditions depicted for each fertilization treatment. Error bars indicate SEM and light grey dots show raw data. Negative values indicate net fluxes from atmosphere to peat
