You quickly hop on the internet and search for tips and tricks to a greener lawn only to find there’s no simple solution, there’s work involved. The principle of having to take care of your lawn in order to produce results is reflected across most areas of work. People working in ...

  • When oxygen makes pollution worse

    Oxidation of sulfides in mining wastes produces high concentrations of sulfate, iron, and other metals, and frequently also very low pH values. 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 piles. In waste rock piles with high permeability and ...

  • Impact of floods on soils

    A recent study conducted in the Midwestern United States examined the effects of harsh wet conditions on both cultivated and uncultivated soils, vastly advancing the knowledge of water’s effects on aggregation. Soil aggregation is an important soil attribute that is related to the physical-chemical state of the soil, and is one of the essential processes that determine soil quality. During the ...

  • Wind drives oxygen transport in Arctic waste rock

    The growth of the diamond mining industry in Canada’s Northwest Territories has led to significant economic benefit to the region with three operating mines producing approximately 13% of the world’s diamonds in 2008, according to the Mining Association of Canada. However, the long-term benefit to northern communities will depend on careful environmental management of mining activities. The ...

  • Even soil feels the heat

    Twenty years of field studies reveal that as the Earth has gotten warmer, plants and microbes in the soil have given off more carbon dioxide. So-called soil respiration has increased about one-tenth of 1 percent per year since 1989, according to an analysis of past studies in this week's issue of Nature. The scientists also calculated the total amount of carbon dioxide flowing from soils, which ...

  • Genome of nitrogen-fixing, soil-living bacterium sequenced

    A collaboration of researchers, which includes scientists at the Virginia Bioinformatics Institute (VBI) and Virginia Tech, have completed the genome sequence of Azotobacter vinelandii, uncovering important genetic information that will contribute to a more complete understanding of the biology of this versatile, soil-living bacterium. The work will help advance research on A. vinelandii's role ...

  • Landfill cover soil methane oxidation underestimated

    Landfilled waste decomposes in the absence of oxygen and results in the production of methane. Landfills are classified as the second-largest human-made source of CH4 in the U.S. Additionally, landfill gas contains numerous non-methane hydrocarbons that are either volatilized directly from waste materials or produced through biochemical reactions during waste degradation. Microbial methane ...

  • Scientists turn oily soil into productive ground

    Scientists are cleaning soil contaminated by oil spills in a way that saves energy and reclaims the soil's productivity, using a process known as pyrolysis, which involves heating contaminated soils in the absence of oxygen. They use a process known as pyrolysis, which involves heating contaminated soils in the absence of oxygen. This approach is much better for the environment than standard ...

  • Shifts in soil bacteria linked to wetland restoration success

    A new study led by Duke University researchers finds that restoring degraded wetlands -- especially those that had been converted into farm fields -- actually decreases their soil bacterial diversity. But that’s a good thing, say the study’s authors, because it marks a return to the wetland soils’ natural conditions.“It sounds counter-intuitive, but our study shows that in restored wetlands, ...

  • Basin wetlands checked for acid sulfate soils

    More than 1000 wetlands throughout the Murray-Darling Basin are being assessed to determine the risk posed to them by acid sulfate soils, the Murray-Darling Basin Commission (MDBC) announced today. Chief Executive Dr Wendy Craik AM said the MDBC was funding the project which is being carried out by State agencies, the Murray-Darling Freshwater Research Centre, CSIRO, Southern Cross University and ...

  • Biogenie Inaugurates a Soil Treatment Facility in Yellowknife

    Yellowknife, October 11, 2006 – Biogenie, a company which is specialized in the remediation of contaminated sites, recently inaugurated a contaminated Soil Treatment Facility (STF) on the premises of Yellowknife’s municipal landfill site. Built under a partnership approach with the City of Yellowknife, the STF will improve the contaminated soil management practices at the landfill site while ...

  • Changing climate may lead to devastating loss of phosphorus from soil

    Crop growth, drinking water and recreational water sports could all be adversely affected if predicted changes in rainfall patterns over the coming years prove true, according to research published in April in Biology and Fertility of Soils. Scientists from Biotechnology and Biological Sciences Research Council (BBSRC)-funded North Wyke Research have found for the first time that the rate at ...

  • Common soil bacteria could clean up nuclear contamination

    Researchers are studying some common soil bacteria that “inhale” toxic metals and “exhale” them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago. Using a unique combination of microscopes, researchers at Ohio State University and their colleagues were able to glimpse how the Shewanella oneidensis bacterium ...


  • EC hosts high-level conference on soil and climate change

    The European Commission this week hosted a high-level conference on the relationship between soil and climate change, and the role of soil management in climate change mitigation and adaptation. Organic matter plays a fundamental role supporting soil fertility, retaining water, sustaining biodiversity and regulating the global carbon cycle. But organic matter is in decline, and the conference ...

  • Gas sensors `see` through soil to analyze microbial interactions

    Rice University researchers have developed gas biosensors to “see” into soil and allow them to follow the behavior of the microbial communities within. In a study in the American Chemical Society’s journal Environmental Science and Technology, the Rice team described using genetically engineered bacteria that release ...

  • Two key factors control phosphorus movement from soil to groundwater

    New insights into how phosphorus leaches into groundwater could help reduce its potential impact on water and the environment, a UF/IFAS scientist says. Phosphorus poses an environmental threat when it travels from soils to open water bodies, including lakes, streams and rivers. When too much phosphorus is applied to soils, the ground cannot hold all of the chemical, said Gurpal Toor, an ...
