Overview

Detailed view

We evaluated the amount of waterstable soil aggregates at the Bombuscaro NUMEX plots. We included various potential soil parameters that are known to have an effect on the aggregation process.

Soil data of NUMEX plots measured in 2013. Percentage of C and N, as well as soil pH were determined.

Representative samples of leaves from all plants of the herbal- and shrublayer in subpots of 1x1 m² in size. Leaves were collected during the dry season.

For the determination of the C/N ratio in leaves of understory plants we collected representatively leaves from 27 plots in natural and disturbed forest sites (1000 to 3000 m a.s.l.) in the dry season in 2014. We considered the shrub layer and the herbal layer of 30 randomly chosen m2 per plot. The collected leaves were dried and prepared to determine the C/N ratio with a C/N Analysator (Vario EL III).

Tree functional traits (leaf area, specific leaf area, foliar N, foliar P, leaf toughness, bark thickness, wood specific gravity, sapwood vessel density, sapwood vessel diameter, sapwood-specific conductivity) recorded in the area of the San Francisco reserve.

Tree functional traits (leaf area, specific leaf area, foliar N, foliar P, leaf toughness, bark thickness, wood specific gravity, sapwood vessel density, sapwood vessel diameter, sapwood-specific conductivity) recorded in the premontane forests of the Podocarpus National Park (Bombuscaro entrance).

Tree functional traits (leaf area, specific leaf area, foliar N, foliar P, leaf toughness, bark thickness, wood specific gravity, sapwood vessel density, sapwood vessel diameter, sapwood-specific conductivity) recorded in the upper montane forests of the Podocarpus National Park (Cajanuma entrance).

Soil texture, CN & bulk density sampled in 30cm depth allong transects in the ECSF area.

Leaf functional traits (dry matter content, toughness, thickness, leaf area, specific leaf area, foliar C, foliar N, foliar C/N ratio, foliar P, foliar Al, foliar Ca, foliar Fe, foliar K, foliar Mg, foliar Mn, foliar S) recorded in 52 common tree species collected within the Respect coreplots in Bombuscaro, San Francisco and Cajanuma in February and March 2019.

The dataset includes chemical properties of the organic layer and mineral soil on forest and pastures core plots in Bombuscaro 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.
