Supporting data: Temporary waterlogging alters CO2 flux dynamics but not cumulative emissions in cultivated mineral soils

Data for publication: Kronberg et al. Temporary waterlogging alters CO2 flux dynamics but not cumulative emissions in cultivated mineral soils. The manuscript has been submitted to Biogeosciences (EGUSPHERE) with an identifier egusphere-2025-2801. The reader is referred to the above article for the detailed methodology of data collection. The data was collected from a soil monolith experiment conducted at University of Helsinki greenhouse facilities in 2021-2022. The experimental procedure has been described in detail in Kronberg et al. (2024). Kronberg, R., Kanerva, S., Koskinen, M., Polvinen, T., Heinonsalo, J., & Pihlatie, M. (2024). Controlled soil monolith experiment for studying the effects of waterlogging on redox processes. Geoderma, 452, 117110. https://doi.org/10.1016/j.geoderma.2024.117110 Methods: Soil temperature (T) and soil volumetric water content (SVWC) were measured with Teros12 sensors (METER Group, USA). CO2 and CH4 fluxes were measured with a non-dispersive infrared gas analyzer (Li 850, Li-cor Environment, USA) and laser spectroscopy-based gas analyzer (LGR N2OM1-919, ABB Group, Switzerland), respectively. Pore water dissolved carbon concentrations (DC, DOC, DIC) were measured with combustion catalytic oxidation method (TOC-L, Shimadzu, Japan). Porewater dissolved Fe concentration was measured colorimetrically with a 1,10-phenantroline method.
