We measured the fluxes of N 2 O, CO 2 , and CH 4 after adding 9 t ha −1 biochar on an agricultural soil in Southern Finland in May 2009. We conducted these measurements twice a week for 1.5 months, between sowing and canopy closure, to capture the period of highest N 2 O emissions, where the potential for mitigation would also be highest. Biochar addition increased CH 4 uptake (96% increase in the average cumulative CH 4 uptake), but no statistically significant differences were observed in the CO 2 and N 2 O emissions between the biochar amended and control plots. Added biochar increased soil water holding capacity by 11%. Further studies are needed to clarify whether this may help balance fluctuations in water availability to plants in the future climate with more frequent drought periods. 2.
