Platform data

Overview

Detailed view

AMF root colonization of roots extracted from the upper soil layer (5cm) at all NUMEX plots. Roots are stained with Trypan Blue, AMF root colonization is examined by the line-intersect method.

The dataset includes physical properties of the mineral soils on forest and pasture core plots in Bombuscaro during the 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. Bulk density was measured in the topsoil with undisturbed soil cores. Soil texture was measured with a combined sieving and pipetting method after oxidation of organic matter and chemical dispersion of aggregates.

Weekly time series of precipitation data (water fluxes, electrical conductivity, pH values) from the Bombuscaro site at 1000 m a.s.l. located at the climate station. The updated weekly time series extends between March 2018 and December 2023. Precipitation was sampled with 5 Hellmann-type collectors. Replicates were collected, volume-weighted and bulked to one sample per plot. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory at the ECSF.

Aggregated values from 2018 are incomplete (March to December).

Corrected plots from Bombuscaro, ECSF, Cajanuma, Zamora and Laipuna region as shape files.

For the seedling transplantation experiment conducted in NUMEX plots in Bombuscaro using as a target species Pouteria torta for monitoring during one year the effects of fertilization in a common species. This data set correspond to the initial measurements of the experiment

Attributes measured and morphological attribute analyzed in 2012  after harvesting the seedling transplantation experiment using Pouteria torta species.

Orthomosaic containing georeferenced NDVI Values from Bombuscaro forest aquired with a low flying UAV.

Abundance of ant species were collected during the wet and the dry season 2014 on the core plots and intermediate elevation levels (1000, 1500, 2000, 2500, 3000) on disturbed and undisturbed forest plots.

Measurements of gas flux (CO2, CH4, N2O) in canopy soils of NUMEX plots on four dates (Sept/Nov 2011 and Jan/April 2012). Measurements were taken in 3 of the 4 NUMEX blocks at each elevation; treatments measured included C, N, NP and P.

Gas fluxes were measured by incubating intact soil cores.
Gas samples were analyzed on a gas chromatograph with a FID and ECD.
Note that the units for CO2 are mg CO2-C m-2 h-1 (not g CO2-C).

Ongoing data collected from Bombuscaro Thies climate station.

Raw data, initial visual control only. Use data with great care, errors might be included.

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.

The dataset includes the chemical properties of the soil organic layer associated with the PFT trees species of the core plots in Bombuscaro, San Francisco and Cajanuma. The samples were taken during sampling campaigns in 2018 and 2019. Respresentative samples were taken from the whole organic layer at five locations close to each tree, bulked in the field, dried at 40 °C at the ECSF and transported to Germany for laboratory analyses. Total carbon, nitrogen and sulfur were measured by elemental analysis via thermal combustion in milled aliquots.

Monthly measurement of soil temperature and soil gas fluxes (CO2, N2O) in the NUMEX plots in Bombuscaro, ECSF und Cajanuma

Monthly measurements of gas fluxes were performed using static vented chambers.
Soil temperature was taken simultaneously with gas measurements.
