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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
