Carbon sequestration and nitrogen loss drive the evolution of French forest soils: dataset

This dataset contains forest floor and mineral soil chemical properties down to 40 cm depth for two soil sampling campaigns carried out at around 15-year time interval (campaign 1 from 1993 to 1995, campaign 2 from 2007 to 2012) within the 102 permanent plots of the French Network for the Monitoring of Forest Ecosystems (RENECOFOR).

Data are reported for soil organic carbon (Corg), total nitrogen (Ntot), C/N ratio (CNratio), exchangeable calcium (Caexch), exchangeable magnesium (Mgexch), exchangeable potassium (Kexch), exchangeable aluminium (Alexch), effective cation exchange capacity (ECEC), extractable phosphorus (P), pH CaCl₂ and pH H₂O.
