Climate change will enforce sulphur deficiency in crops

28.03.2008
Federal Research Centre for Cultivated Plants (Julius Kühn Institute) established first risk map for Germany

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 research branch of the Federal Ministry of Food, Agriculture and Consumer Protection (BMELV) has a new structure since January 1st, 2008.

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.

Im Focus: ScanCut project completed: laser cutting enables more intricate plug connector designs

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...

Im Focus: TU Graz Researchers synthesize nanoparticles tailored for special applications

“Core-shell” clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient.

Whether in innovative high-tech materials, more powerful computer chips, pharmaceuticals or in the field of renewable energies, nanoparticles – smallest...

Im Focus: Tailored light inspired by nature

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.

Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
