A total of about 3100 soil sample were taken nationwide within the context of the German agricultural soil inventory by Thünen Institute. What takes place on the field and what happens to the soil samples in the laboratory? This video tells us the story.
Maize-Beans – Organic crude feed with higher value?
How well is a combination of maize and beans suited as a feedstuff for dairy cattle and fattening pigs? This topic was studied by our scientists in Trenthorst. (Video in German)
The German Forest Inventory is concerned with more than just tree population studies. Can the forest ecosystem maintain its biological diversity in the future? (Video in German)
Filtering water, storing water, using water: those are among the life maintaining functions of our forests. This film shows how we observe and study the trees at work (in German).
To ensure that only legally logged timber, especially from tropical forests, is sold, we develop tests and reference databases with which the origin of wood can be tracked along the entire value chain (in German).
In order to check whether wood has been logged legally, it may be necessary to know not only the species but also the region from which it originates. This is possible with genetic testing. The video shows how it works (in German).
Scientists in Eberswalde are using the "Drylab" field laboratory to investigate how young beech trees of different origins react to drought. The film presents the "Drylab".
The Thünen Institute maintains three research vessels for marine studies. Differing in size and specialization, these vessels are put into use for very different expeditions. The video introduces the vessels and shows their activities above and under water.
The cod stock in the eastern Baltic Sea is in such poor condition that it should not be fished at all. The newly developed bottom trawl "Roofless" enables the selective catching of flatfish while at the same time allowing the cod to escape.
How can the selectivity of trawl nets be improved to reduce by-catch? The film shows the development of a net that provides an "emergency exit" for unwanted flatfish in mixed cod fishing.
How do you know how much fish there is in the North Sea? Does climate change affect fish stocks? Scientists at the Thünen Institute of Sea Fisheries answer these and other questions by taking fish and plankton samples every spring and autumn with a research vessel – and have done so for 50 years.
Climate change endangers many forests in Central Europe. The high dynamic of changing growing conditions impede the natural adaptation of forest ecosystems. The international project SUSTREE is aimed at supporting the adaptive ability of major tree species through seed transfer from today allready dry and warm regions.
The film provides insights into the F.R.A.N.Z. project. Based on three demonstration farms, it informs about the intensive cooperation between agriculture and research to increase biodiversity on agricultural land. Various biodiversity measures implemented on the farms are presented, as well as areas of ecological and socio-economic accompanying research.
