Soil chemistry and soil bulk density data from restored grasslands and reference sites in Germany

This dataset provides information on soil chemistry and soil bulk density as part of the Grassworks project, which investigates the restoration of species-rich grasslands in Germany. Grasslands are globally threatened ecosystems, and the project aims to identify factors that contribute to successful restoration, focusing on ecological complexity and stakeholder engagement. Data was collected from 187 grassland sites across three regions in North, Central, and South Germany, each with distinct socio-economic and ecological characteristics. Sampling occurred between 2022 and 2023 and included 40–41 restored grassland sites and 20–25 reference sites (10–12 positive, 10–13 negative) per region. At each site in March or early April at each vegetation plot, we took soil samples (pooled from six soil cores, 20 mm diameter) that were further pooled into one sample per site and analyzed for total soil organic carbon (SOC), total nitrogen content, pH, and soil texture as well as microbial biomass (carbon based). Additionally, soil bulk density was measured at vegetation plots per site, to enable future assessment of carbon sequestration over time. Soil and bulk density samples were taken at two depths: 0–10 and 10–30 cm.

Surface water parameters (pH, specific conductivity, salinity, nutrients, oxygen, sulfate and chloride concentrations, DOC/DIC) (Table 4)

Surface water parameters were measured in parallel to the gas measurements and soil coring for microbial analyses. Most surface water variables (pH, specific conductivity, salinity, nutrients, oxygen, sulfate and chloride concentrations, DOC/DIC) were measured in-situ using a multiparameter digital water quality meter or taken to the laboratory as water samples for further analysis. While surface water analysis was only conducted in the drainage ditch before rewetting, it was done along the entire transect after rewetting.

Pore water and soil variables (pH, specific conductivity, nutrients, metals, sulfate and chloride concentrations, CNS) (Table 3)

Pore water parameters were measured in parallel to the gas measurements and soil coring for microbial analyses. Pore water/soil variables (pH, specific conductivity, nutrients, metals, sulfate and chloride concentrations, CNS) were either measured in-situ or taken to the laboratory as soil samples. Pore water/soil analysis was mostly conducted before rewetting and only repeated occasionally after rewetting where possible.

Distribution of contaminants from the Elbe outflow into the North Sea (German Bight) based on water samples from the MOSES cruise Sternfahrt 10 in 2023

The Sternfahrt-10 of the MOSES campaign, from 29th August until the 15th of September 2023, had two objectives. One was to follow the dispersion of pollutants transported by the Elbe water into the North Sea, previously observed during the Elbe-Freshwater and Elbe-Tidal cruises. And second the distribution of the Elbe water within the German Bight. Therefore, drifter groups were deployed to follow individual water parcels. Those drifters were followed subsequently by three ships (RV Ludwig Prandtl, RV Littorina, RV Mya II), to extend the time period of measurements. Along the tracks, water samples were taken close to the drifters, alternatively at stations from previous cruises, resulting in 12 to 24 sampling points per week. In terms to detect the concentration of a variety of nutrients and carbon compounds from the south-eastern North Sea up to the island Amrum. Additionally, basic hydrographic parameters and greenhouse gases were sampled continuously throughout the whole cruise. Those results are not part of the present dataset, but can be found here, https://doi.org/10.1594/PANGAEA.971874. To ensure the comparability of the measured parameters a transportable container laboratory was passed from ship to ship always equipped with the same sensor systems. Just for specific water samples some special equipment was added. A map of the different tracks as well as information about the used sensors and data treatment, you can find in the additional material. For more detailed information about the MOSES Project and the cruise Sternfahrt-10, see the article cited in references.

Physicochemical soil property data for archive samples of the Saxon agricultural soil monitoring program

The continuous agricultural soil monitoring program (BDF) by the Saxon State Office for Environment, Agriculture, and Geology (LfULG) is operational since 1995, collecting and analysing samples periodically from 60 monitoring sites across Saxony, Germany. This dataset provides physicochemical soil property data for 920 archive samples available from the Saxon soil information system FIS Boden, including soil organic carbon, total nitrogen, various total and extractable elemental contents, soil pH, cation exchange capacity, and particle size distribution. Additional soil physical data (bulk density, soil water retention) have been merged from undisturbed sample data, resulting in a total of 123 variables, though with varying availability. This dataset provides the majority of reference data for the mid-infrared soil spectral library for agricultural soils in Saxony, Germany.
