Effects of rainfall events on the water storage characteristic of a shallow water table site - lysimeter data10.4228/ZALF.DK.81Spreewald, GermanyShowOnMapView sample data preperiodDownload dataCreative Commons Attribution-NonCommercial 4.0
The dataset contains measurment data from a weighable groundwater lysimeter in the Spreewald wetland. Water budget values and water levels were selected for 29 rainfall events > 10 mm between May 2010 and September 2012. The parameters were evaluated for different points of time and periods after and before the rainfall events. Special focus was set on water storage characteristics of the thin unsatureted zone of the shallow water table site. The data shows the effect of different assumptions (equilibrium conditions vs. dynamic conditions) on the estimated exhaustion of the unsaturated zone.

Description type: Abstract: On set-aside areas, which there agricultural used for a long, the soil parameters have a special dynamic. After a long period of anthropogenic use they are moving back to a level typically for the site without any use. For an area on a sandy site (sandy loam-soil, German soil quality index for arable land: 25...35, mean (1988-2017) annual precipitation: 544 mm, mean (1988-2017) annual temperature: 9.3°C) in the Müncheberg area (Federal State of Brandenburg, Germany) for the period 1992-2017 measured values for the most important soil parameters with fast dynamics (NO3, NH4, Nan, soil water) and slow dynamics (pH, Nt, P, K, Mg, Ct) are available for three soil layers (0-30 cm, 30-60 cm and 60-90 cm). Generally these measured values are available annually in spring time. For the years 1992-1996, however, several measurements per year are available also until the end of the vegetation. The area, which has been set-aside since 1992, was used for agriculture until 1991 (recurrent winter rye cultivation). Since 1992 the set-aside area was mulched annually to prevent succession.

The data set contains daily time-step observed and scenario climate data on a European grid with 25 km x 25 km spatial resolution and is intended to be used for crop modelling applications. The dataset covers the period 1980-2010 for observations (for a baseline period of 1981-2010 and the year 1980 for crop model simulations with sowing dates in the autumn) and the periods 2040-2069 and 2070-2099 for 5 GCMs x 2 forcing scenarios (RCP4.5 and RCP8.5) and 2 GCMs with RCP2.6. The Joint Research Centre’s (JRC) Agri4Cast gridded dataset was used for the baseline. The scenarios have been calculated using an enhanced delta change method that applies changes in aspects of temperature and precipitation variability in addition to changes in mean climate.

Data set for a method of non-destructive determination of the fresh sugar beet mass between emergence and harvest10.4228/ZALF.DK.58North-East GermanyShowOnMapView sample dataDownload zipCreative Commons Attribution-NonCommercial 4.0

Mirschel, Wilfried

Description type: Abstract: Up to now, it has not been possible to determine the beet biomass of sugar beet non-destructive dynamically during the growth process. This value is important for the parameterisation of crop growth models. Studies on individual beets show that there is a close relationship between the beet diameter at the widest (thickest) point and the beet biomass. To quantify this relationship data were colleced. The data set contains four sugar beet varieties from the 1990s for three different locations (Müncheberg, Hohenfinow and Dedelow) in Brandenburg, Germany. The data set contains more than 6,700 data records. The measurements were realized in approx. 14-day intervals between rising and harvesting. Different cultivation systems (intensive, organic, extensive) were taken into account additionaly with and without use of irrigation.

Dust measurements in Inner Mongolian grasslands10.4228/ZALF.DK.54Inner MongoliaShowOnMapView sample data (samples_chemistry)Download zipCreative Commons Attribution-NonCommercial 4.0

Abstract:
The dynamics of dust emission and deposition in the grasslands of Inner Mongolia were investigated during two measuring campaigns in spring months 2005 and 2006 in grazed and un-grazed plots in Inner Mongolia grassland. # Both processes are determined by the grazing intensity, whereas dust deposition rates are modified additionally by the topography. Because grazing intensity of the previous year influences the height and density of standing death vegetation, it could therefore be measured through the surface roughness length (z0). Fine dust concentrations and wind velocity were measured during dust storm events
Technical Info:

Aquatic sedimentation rates and physicochemical data in two ponds: Rittgarten and Kraatz10.4228/ZALF.2018.344Uckermark (Kraatz, Rittgarten)ShowOnMapView sample dataDownload complete datasetCreative Commons Attribution 4.0 International

​Kleeberg, Andreas; Neyen, Marielle; Kalettka Thomas

Sedimentation was studied in two kettle holes close to Rittgarten (RG) and Kraatz (KR), Uckermark, NE Germany. Pairs of cylindrical traps at three sites in each kettle hole were sampled biweekly (June 2013–July 2014). Mean fluxes decreased with decreasing water level. KR was Fe-dominated binding P, and had submersed macrophytes. RG was Ca dominated and had low Fe concentrations suggesting that both apatite and oxidized Fe compounds equilibrated P release, with finally a surplus in P.

Combining a root exclusion technique with continuous chamber and porous tube measurements for a pin-point separation of ecosystem respiration in croplands10.4228/ZALF.2017.336DedelowShowOnMapView sample dataDownload complete datasetCreative Commons Attribution-NonCommercial 4.0

​Hoffmann, Mathias; Wirth, Stephan; Beßler, Holger; Engels, Christof; Jochheim, Hubert; Sommer, Michael; Augustin, Jürgen

To better assess ecosystem C budgets of croplands and understand their potential response to climate and management changes, detailed information on the mechanisms and environmental controls driving the individual C flux components are needed. This accounts in particular for the ecosystem respiration (Reco) and its components, the autotrophic (Ra) and heterotrophic respiration (Rh), which vary tremendously in time and space. This dataset presents results of a study, which uses a combination of a root exclusion experimental design and continous automatic chamber and below soil porous tube measurements to derive the Reco flux components. Measurements were carried out for winter wheat (Triticum aestivum L.) during the crop season 2015 at an experimental plot located in the hummocky ground moraine landscape of NE Germany.
