Abstract:
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.
