Resumen:

The dataset includes physical and chemical properties of the organic layer and mineral soil at NUMEX San Francisco during sampling campaigns from 2007 to 2009. Following properties were measured: bulk density, horizon thickness, sand, silt and clay content, concentrations of Al, Fe, Mn, Zn, C, N, S, P, K, Na, Mg, Ca, cation exchange capacity, exchangeable cations Ca, Na, Mg, K, Al, Fe, delta 13C and delta 15N values.

Resumen:

Monthly time series of measured concentrations of Al, Cu, Fe, Mn, Zn, C, N, S, P, K, Na, Mg, Ca in litterfall at NUMEX San Francisco between 2007 and 2013. Litterfall was collected on all 20 plots at NUMEX on 6 subplots per plot (A-F) with polyethylene mesh traps (0.6 x 0.6 m). On each plot, two of the six litterfall traps were randomly sampled monthly. The samples were dried at 40 °C for one week and stored at the ECSF until transport to Germany or Switzerland for chemical analyses. The two collected replicates were bulked per plot and collecting interval resulting in one litterfall sample per plot and month. Samples were ground to <50 µm with a planetary ball mill (Retsch PM200, Haan, Germany) prior to elemental analysis of C, N, and S by thermal combustion (Elementar Analysensysteme, Hanau, Germany) and acid microwave digestion with concentrated HNO3. Element concentrations in the digested samples were measured by AAS, ICP-OES or ICP-MS.

Resumen:

Monthly aggregated time series of litterfall in the ECSF area in the microcatchment Q2. Litterfall was sampled weekly on the 3 transects of Q2 (Q2.1, Q2.2, Q2.3) with 3 polyethylene mesh collectors (0.5 x 0.5 m) per transect. The samples were dried at 40 °C for one week and the mass of the dry litterfall was recorded. The masses of the 3 replicates at upper, middle and lower slope were averaged per transect and collecting interval and subsequently aggregated per month and transect.
