A daily time-step observed and scenario climate dataset on a European grid for crop modelling applications10.4228/ZALF.DK.94EuropeShowOnMapView sample dataCreative Commons Attribution 4.0

​Fronzek, Stefan; Webber, Heidi; Rötter, Reimund; Ruane, Alex; Ewert, Frank;

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.

Manual leaf area measurement on individual sugar beet plants taking plant density and irrigation into account10.4228/ZALF.DK.91MünchebergShowOnMapView sample dataDownload complete datasetCreative Commons Attribution 4.0

​Mirschel, Wilfried

For sugar beet growth models, knowledge of the development of the photosynthetically active leaf apparatus with its up to more than 50 individual leaves per beet plant as a source of assimilate production is very important. Because the measurement using leaf area index (LAI) meters from above allows only a limited measurement and does not cover the total leaf area of all existing individual leaves, it is necessary to carry out manually leaf area measurements for individual sugar beet plants over the whole growth period without destroying the leaves. For this reason, a special measuring methodology was developed and applied. On the experimental fields of the Research Centre for Soil Fertility Müncheberg (FZB Müncheberg) (location: 52°01`N, 14°07`E, 14°07`Eastern latitude; location type: D 2a; soil type: sandy-loamy soil; German soil quality index: 26; average (1951-1981) annual precipitation: 544 mm; average (1951-1981) annual temperature: 8.2°C) leaf area measurements were carried out in different experiments with sugar beets between 1979 and 1982. In each experimental variant, the leaf areas of 8 individual plants were measured between emergence and harvesting of the sugar beet at intervals of approximately 7 days. Between end of May and mid-October usually about 20 measurements were realized. The leaf area is given in cm2 per sugar beet plant. Experiments with different crop densities (60,000, 80,000 and 100,000 sugar beet plants per hectare) as well as without and with irrigation (based on pen evaporation or based on model-added irrigation scheduling system EDV-BB) were taken into account.

The global trade of goods (car tires and ornamental plants in particular) has facilitated the accidental transport of eggs, pupae and larvae of the Asian bush mosquito (Aedes japonicus japonicus) to North America and Europe. On both continents, the species has spread over wide areas and became established in several geographical regions. Since it is a potential vector of pathogens of humans and livestock, distribution and dissemination maps are urgently needed to implement targeted surveillance and control in case of disease outbreaks. Previous distribution models for Europe were relatively inaccurate because land-use effects remained unconsidered. Our approach is based on the fuzzy modelling technique combined with biological expertise that enabled to precisely define the interactions between the three most relevant factors determining the occurrence of this mosquito species: climate, wind and land-use. The model combines different spatial resolutions of data for Germany and achieves a much higher degree of accuracy than previous distribution models. Our results reveal that a well-suited landscape structure can even facilitate the occurrence of Aedes j. japonicus in a climatically unsuitable region. Vice versa, unsuitable land-use types such as agricultural landscapes and agroforests reduce the occurrence probability in climatically suitable regions. Our study demonstrates the importance of regional influences on propagation models for invasive mosquito species, in addition to global processes such as international trade and climate change.

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 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.

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 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 4.0

Hoffmann, Carsten

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
