Global Positioning Systems prepare a digital map for precise soil acidity identification
A study conducted by Iowa State University soil scientists suggests Global Positioning Systems (GPS) available to corn and soybean producers can markedly improve the management of soil acidity and lime application. The research is published in the January/February 2003 issue of Agronomy Journal.
Soil acidity can limit plant growth, and due to soil formation processes and management practices, there exists large pH variability within producers’ fields. Lime often needs to be applied to maintain profitable crop production; however, traditional methods make it impractical to change lime application rates over a field. Producers usually apply a uniform rate although they recognize only a small proportion of the field receives the optimum application.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
