The study was led by Humberto Blanco-Canqui at Kansas State University at Hays, Kan., and Maysoon Mikha at the ARS Central Great Plains Research Station in Akron, Colo. ARS researchers Joe Benjamin and Merle Vigil at Akron were part of the research team that studied four sites across the Great Plains: Akron; Hays and Tribune, Kan., and the University of Nebraska at Sidney.
No-till stores more soil carbon, which helps bind or glue soil particles together, making the first inch of topsoil two to seven times less vulnerable to the destructive force of raindrops than plowed soil.
The structure of these aggregates in the first inch of topsoil is the first line of defense against soil erosion by water or wind. Understanding the resistance of these aggregates to the erosive forces of wind and rain is critical to evaluating soil erodibility. This is especially important in semiarid regions such as the Great Plains, where low precipitation, high evaporation, and yield variability can interact with intensive tillage to alter aggregate properties and soil organic matter content.
Tillage makes soil less resistant to being broken apart by raindrops because the clumping is disrupted and soil organic matter is lost through oxidation when soil particles are exposed to air.
A paper on this research was published in a recent issue of the Soil Science Society of America Journal.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
