Data for: Stabilisation of soil organic matter with rock dust partially counteracted by plants

In this study, the effect of rock dust addition on both soil inorganic and
organic carbon contents was investigated. Soil chemical changes were
measured, including soil organic carbon (totals and fractions), soil
inorganic carbon, pH, electric conductivity, and water-extractable and
ammonium acetate-extractable ion levels (Ca, Mg, Al, Fe, Mn, Fe, Zn, Si).
In addition, the effect of plants on soil chemistry and rocks on plant
growth (biomass) and plant ion uptake was studied. The results
demonstrated rock weathering during the 6 months incubation period and a
stabilisation of organic carbon. Plants partially counteracted the
stabilisation of soil organic carbon. This was attributed to interactions
between soil chemical changes induced by rock dust, plant exudation, and
subsequent soil organic carbon stabilisation mechanisms.
