The dataset includes chemical properties of the organic layer and mineral soil on forest and pastures core plots in San Francisco during sampling campaigns in 2018 and 2019. Three soil profiles were established on each core plot. Respresentative samples were taken from each horizon, dried and transported to Germany for laboratory analyses. Available nitrogen (NH4-N and NO3-N) was immediately extracted in the laboratory of the ECSF with 1 M KCl. The extracts were frozen and sent to Germany for laboratory analyses by continuous flow analysis. Following properties were measured in the < 2mm soil fraction: available P after extraction by the Olsen method with 0.5 M NaHCO3 and measurement by continuous flow analysis, total element concentrations Al, Fe, Mn, Zn, C, N, S, P, K, Na, Mg, Ca after microwave pressure digestion with HNO3, H2O2 and HF and measurement by by ICP-OES or ICP-MS, effective cation exchange capacity and exchangeable cations Ca, Na, Mg, K, Al, Fe, Mn after unbuffered extraction with 1M NH4NO3 and measurement by ICP-OES.
