The dataset consists of measurements of weathering indicators according to earthworm presence and survival. Data was collected within the BAM! project (Bio-Accelerated Mineral Weathering), examining the potential of soil organisms to enhance mineral weathering for carbon sequestration. Data was obtained within 8 rounds of column-experiments carried out between March 2022 and September 2023 in the laboratory of the Wageningen University & Research. The dataset includes data for paired treatments with and without earthworms and relative survival rate where a series of weathering indicators were measured, as solid inorganic carbon, dissolved inorganic carbon, alkalinity, pH, electrical conductivity and major ions (calcium, potassium, magnesium, silicon, iron, phosphorus).
