Still 25 years ago, farmers received the plant nutrient sulphur for free because clean air acts had not come into force by then. Desulphurisation of fumes resulted in a continuously declining atmospheric sulphur input each year so that farmers have to fertilise sulphur regularly in order to warrant a sufficient sulphur supply and crop productivity.
Oilseed rape is particularly sensitive to sulphur deficiency. Oilseed rape is one of Germany's most important crops for the production of bio-energy. Problem: High rainfall will cause exhaustive leaching of plant available sulphate on agricultural soils.
Parallel to the predicted climate change in the next decades, the risk of sulphur deficiency in agricultural crops will increase, so the forecast of geo-ecologist Knut Hartmann and Dr. Holger Lilienthal, both researchers at the Institute for Crop and Soil Science of the Julius Kühn Institute (JKI). They extended and implemented the "MOdel for Predicting Sulphur deficiency (MOPS) into a Geographical Information System (GIS).
By means of the same technology the JKI researchers computed that this year about 38 % of the arable land in Germany is subjected to a high risk of sulphur deficiency. In 60 years (with an expected temperature increase of two degrees Celsius, an increase of winter precipitation by 30 % and a summer rainfall decrease by 30%, the area of land with a high risk of sulphur deficiency will increase to nearly 50%. Without additional efforts in fertilisation and crop protection, the costs of the resulting yield losses for oilseed rape and wheat in Germany, will add up to one billion euros for each crop. For risk assessment MOPS does not only take climatic factors into consideration, but also site-specific, soil-physical and hydrological properties.Explanation Julius Kühn Institute:
The Federal Biological Research Centre for Agriculture and Forestry (BBA), the Federal Centre for Breeding Research on Cultivated Plants (BAZ) and two institutes of the Federal Agricultural Research Centre (FAL) were merged to Julius Kuehn Institute (JKI), Federal Research Centre for Cultivated Plants.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
