Short summary

We studied how off-season waterlogging affects CO₂ fluxes and dissolved carbon dynamics in cultivated boreal mineral soils. The study was conducted with intact soil profiles in a greenhouse. Waterlogging reduced immediate CO₂efflux, but CO₂ accumulated in porewater and was released to the atmosphere upon soil drying. Cumulative emissions remained unaltered. Our results suggest that temporary waterlogging does not suppress total CO₂ production in mineral soils as much as commonly assumed.
