The dataset contains...

• the CO2 release and its 13C signal during the 17-day incubations with and without glucose addition (file names CO2-release_17-day-incubation and Gas_13C_17-day-incubation)

• the CO2 release during the 874-day incubation (file names incub1 (= tropical sandy soil), incub2 (= temperate silty soil), and incub3 (= temperate sandy soil)) for each replicate and as the mean for each treatment

• soil sample properties at the beginning of the incubations (file name Soil-properties)

• matlab code for the decay model (file name two_pools_optimization and SOCcontent_2p)

The file "sampleIDs" allows to translate the sample numbers listed in the files to the respective soil and treatment.

Control treatments contain only soil, rock powder (RP) treatments contain soil and basanite rock powder, biochar (BC) treatments contain soil and wheat straw based biochar, Co-application (Co-app.) treatments contain soil and basanite rock powder and biochar, and co-pyrolysis (Co-pyr.) treatments contain soil and rock-enhanced biochar from co-pyrolysis.

This study was conducted as a part of the PyMiCCS project (Pyrogenic carbon and carbonating Minerals for enhanced plant growth and Carbon Capture and Storage) that is part of the CDRterra consortium and was funded by the German Federal Ministry of Research, Technology and Space (BMFTR, FKZ: 01LS2109A).
