Farmers growing corn in the mid-Atlantic region will have a new tool to help them identify appropriate cultural practices for the types of soils in their fields, thanks to research conducted by researchers from Virginia Tech and Colorado State University.
"Soils vary in their ability to hold water," said Mark Alley, professor of crop and soil environmental sciences at Virginia Tech. "If a farmer knows the water-use efficiency of the soils in his field, he has a very important clue on how to manage that field."
Alley developed a formula for accurately determining the water-use efficiency in typical soils in the region. The results of his research were published in the May-June edition of Agronomy Journal. Co-authors of the article are Jon Roygard, a Virginia Tech research associate, and Raj Khosla, assistant professor of soil and crop science at Colorado State University.
Water is the main limiting factor for non-irrigated corn production in the region. The article examines the relationship between no-till corn yields and soil water availability for the purpose of improving water-use efficiency.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
