Overview

Detailed view

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

Soil texture comprising sand, silt, and clay sampled in young landslide. Samples were analysed in the soil physics laboratory of Bayreuth University.

Soil samples were taken from 6 randomly selected plots in three soil depths (0-5, 5-10, 10-20 cm) and litter layer (OiOe1, Oe2Oa) at a shrubland secondary succession site at Loma Chamusquin. At each plot 6-10 soil cores (6 cm in diameter) were taken and each soil depth was mixed to one sample.

Soil samples were taken from 4  plots of each treatment in three soil depths (0-5, 5-10, 10-20 cm) at the repastorization experimental site (see Roos et al. 2010. At each plot 6 soil cores (6 cm in diameter) were taken and each soil depth was mixed to one sample.

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.

Soil texture comprising sand, silt, and clay sampled in llashipa site. Note that, silt and clay have been analysed using particle size laser. Samples were analysed in the soil physics laboratory of Bayreuth University.

Soil samples were taken from 6 randomly selected plots in three soil depths (0-5, 5-10, 10-20 cm) at a 2 year old Setaria-pasture. At each plot 6-10 soil cores (6 cm in diameter) were taken and each soil depth was mixed to one sample.

Soil samples were taken from 6 randomly selected plots in three soil depths (0-5, 5-10, 10-20 cm) at a 50 year old Setaria-pasture. At each plot 6-10 soil cores (6 cm in diameter) were taken and each soil depth was mixed to one sample.

Original data: FOR402 (Phase 2) Creator: Markwardt, Stefanie (AG: B5, AG Huwe)

This dataset has been migrated from the previous FOR402-Database to the FOR816-Database by the Central Data Management Z1/FOR816.
Please keep in mind that the migration included all avilable metainfomation which were accessible through the FOR402-Database. Nevertheless, it can't be guaranteed that no thematic misinterpretation occured in the data/attribute description.
There has been no further discipline specfic control. In any case of ambiguity please contact the dataset creator.

Soil texture sampled from different horizons in Q5 and analysed in the laboratory of the University of Bayreuth (Germany)

Soil texture comprising sand, silt, and clay sampled in clearing in microcatchment 1. Samples were analysed in the soil physics laboratory of Bayreuth University.

The dataset includes physical properties of the mineral soils on forest and pasture core plots in San Francisco 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.
