"This is a demonstration to prove we can continuously generate renewable hydrogen and to study the engineering factors affecting the system performance," said Bruce E. Logan, Kappe professor...
Life Sciences |Compared to fine-grain mine tailings, produced in ore treatment by flotation and other techniques, waste rock is just displaced material comprising large size particles and deposited in waste rock pil...
Ecology, The Environment and Conservation |Shooting ranges are the major source of Pb contamination in Japan where over 600 sites are present mostly in remote locations.Remediation of Pb-contaminated soils in a shooting range is genera...
Ecology, The Environment and Conservation |Soils play a vital role in dealing with the environmental impacts of rising atmospheric carbon levels, primarily CO2, from natural and human activities. The Earth’s carbon budget is a dynamic process....
Ecology, The Environment and Conservation |Contrary to the prevailing view, cereal crops derive the majority of their nitrogen from the soil, not fertilizer. Soils differ considerably in microbial activities that determine nitrogen-supplying p...
Agricultural and Forestry Science |The practice of no-till has increased considerably during the past 20 yr. Soils under no-till usually host a more abundant and diverse biota and are less prone to erosion, water loss, and structural b...
Agricultural and Forestry Science |Phosphorus is one of the key nutrients that can cause algal blooms and related water quality problems in lakes, rivers, and estuaries worldwide. Phosphorus entering waters originates from a variety o...
Agricultural and Forestry Science |Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effec...
Ecology, The Environment and Conservation |Spanish researchers have proved that the combined use of the compost of the waste obtained from olive grinding (alpeorujo) and manure improve agricultural land properties with a high salt content....
Agricultural and Forestry Science |One of the biggest threats to today’s farmlands is the loss of soil organic carbon (SOC) and soil organic matter (SOM) from poor land-management practices.The presence of these materials is es...
Agricultural and Forestry Science |The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but...
Agricultural and Forestry Science |As atmospheric CO2 levels rise, methods to mitigate these increases are becoming very important. Three studies published in the July-August 2008 issue of Soil Science Society of America Journal explor...
Studies and Analyses |Application of waste to meet the nitrogen needs of a crop results in application of excess phosphorus which increases the potential for environmental contamination. Swine fed corn diets with more high...
Agricultural and Forestry Science |Dale Ritchey, a retired soil scientist, and Doug Boyer, a hydrologist at the Agricultural Research Service's Appalachian Farming Systems Research Center in Beaver, W. Va., and colleagues showed ...
Agricultural and Forestry Science |"Wherever man boldly goes his microbial fauna is sure to follow," said Lewis Dartnell, an astrobiologist at University College London. The Russian space station Mir was launched in 1986 and ...
