Researchers with USDA's Agricultural Research Service (ARS) at the agency's Appalachian Farming Systems Research Center (AFSRC) in Beaver, W.Va., are developing constructed or replacement subsoils and topsoils to build better and less-costly sports fields, raingardens and lawns on former landfills, mine lands and other degraded land. ARS is USDA's principal intramural scientific research agency.
The constructed soil research project is in its fourth year. ARS is conducting the research in cooperation with the National Turfgrass Research Initiative, Inc., a joint turfgrass industry-ARS program created in 2007. The initiative draws on the expertise of scientists with ARS and at universities, according to lead scientist Rich Zobel at AFSRC.
The turfgrass industry has set a high priority on improving degraded soils by constructing soils that include readily available rural, urban and industrial byproducts that can be mixed with local soils. These byproduct mixes are being tailored to not only reduce rain runoff and erosion, but also to remove or neutralize pollutants before they reach storm drains.
With lower costs through using inexpensive local byproducts, schools and local parks have a better chance of being able to afford soil replacement for better turfgrass survival. Eliminating compacted soil is the first step toward growing good, robust grass.
The most promising mixture so far includes quarry byproducts and composted chicken litter. It has met predetermined requirements such as the ability to transmit stormwater.
Zobel and his colleagues develop recipes for constructing designer soils from various materials in Ohio, Kentucky, Tennessee, West Virginia, Virginia and southern Pennsylvania.
For the future, Zobel envisions new turfgrass varieties, possibly perennial ryegrass and tall fescue, that will penetrate compacted soil and renovate fields without the need to tear up fields and till compacted soil.

Findings from this research have been published in the Journal of Soil Science and Environmental Management and in USGA Turfgrass and Environmental Research Online.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
