Resumen:	Fortnightly time series of measured concentrations... Resumen: Fortnightly time series of measured concentrations of Cl, PO4-P, Total P, NH4-N, NO3-N, Total N, K, Na, Mg, Ca and Total organic C in throughfall at NUMEX San Francisco. The fortnightly time series extends between August 2007 and March 2013. Throughfall was sampled on the 20 NUMEX plots with Hellmann-type collectors. On each plot 20 replicates were collected, volume-weighted and bulked to one sample per plot. Samples were immediately filtered (4-7 µm) in the laboratory of the ECSF and stored at -20 °C until transport in frozen state to Germany or to Switzerland for concentration measurements.

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.

(2010): Response of nutrient cycles of an old-growth montane forest in Ecuador to experimental low-level nutrient amendments Johannes Gutenberg University Mainz, phd thesis (FOR816dw ID 885): http://www.tropicalmountainforest.org/publications.do?citid=885

Resumen:	Monthly mean nutrient and element concentrations i... Resumen: Monthly mean nutrient and element concentrations in soil solution and monthly sum of litterfall from Q2.2. Soil solution was sampled from below the organic layer (lysimeter), 15cm and 30cm depth. Monthly means were calculated from weekly measurements. The measured nutrients and elements comprise: pH, PO4-P, Ptot, Cl, NH4-N, NO3-N, Ntot, DOC, Ca, K, Mg, Na.
