Are existing large-scale simulations of water dynamics wrong?
Soils are complicated porous media that are highly relevant for the sustainable use of water resources. view more (2008-03-11)
Researchers use dirt to stay one step ahead of antibiotic resistance
Dirt may be a key to how bacteria that infect humans develop a resistance to antibiotic drugs. view more (2006-01-20)
A win-win: U-pick pumpkin farms recycle urban leaves
Americans love pumpkins. The growing popularity of rural fall festivals, grade school farm tours, and "u-pick" pumpkin farms has resulted in an increase in consumer demand for pumpkins throughout the country. view more (2008-12-29)
Robotic whiskers can sense three-dimensional environment
Many mammals use their whiskers to explore their environment and to construct a three-dimensional image of their world. Rodents, for example, use their whiskers to determine the size, shape and texture of objects, and seals use their whiskers to track the fluid wakes of their prey. view more (2006-10-09)
Soil Passage Drinking Water Purification
Soil passage of surface water for drinking water production is effective enough in the removal of viruses. This is one of the conclusions of the research project of Jack Schijven. He hopes to earn his PhD on Monday 2 April at TU Delft. An example of soil passage is dune filtration. “The new law on water facilities states that the chance of a... view more... (2001-03-30)
A Thermometer for the Earth
According to climate change experts, our planet has a fever - melting glaciers are just one stark sign of the radical changes we can expect. view more (2009-10-02)
Soil nutrients shape tropical forests, large-scale study indicates
Tropical forests are among the most diverse plant communities on earth, and scientists have labored for decades to identify the ecological and evolutionary processes that created and maintain them. view more (2007-01-12)
Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't. view more (2008-03-12)
Fresh produce - Potential Risk for Consumers
Vegetables are good examples of minimally processed foods with high risk of contamination and therefore good hygienic measures have to be taken during the production from farm to table. The nature and extent of the health hazards involved in the production and preparation of foods will be considered in depth at the FEMS Congress of European... view more... (2003-05-29)
Limited Biofuel Feedstock Supply?
The United States has embarked on an ambitious program to develop technology and infrastructure to economically and sustainably produce ethanol from biomass. view more (2007-11-29)
Test finds manufactured nanoparticles don't harm soil ecology
The first published study on the environmental impact of manufactured nanoparticles on ordinary soil showed no negative effects, which is contrary to concerns voiced by some that the microscopic particles could be harmful to organisms. view more (2007-03-23)
Study Reveals that Nitrogen Fertilizers Deplete Soil Organic Carbon
The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began. view more (2007-10-30)
Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams. view more (2006-12-12)
Plant pathologists evaluate eco-friendly alternatives to methyl bromide
Alternatives to a powerful pesticide that was found be an ozone depletor are now being evaluated in agricultural production areas of Florida, say plant pathologists with USDA's Agricultural Research Service. view more (2005-06-14)
Beneficial effects of no-till farming depend upon future climate change
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming. view more (2005-10-13)
How plants manage calcium may reduce effects of acid rain
A new understanding of how plants manage their internal calcium levels could lead to modifying plants to avoid damage from acid rain. The pollutant disrupts calcium balance in plants by leaching significant amounts of the mineral from leaves as well as the agricultural and forest soils the plants live in. view more (2007-03-12)
Great Plains' historical stability vulnerable to future changes
A survey of long-term trends in population, farm income, and crop production in the agricultural Great Plains concludes that threats to society and the environment are counterbalanced by "surprising stability" and the potential for short- and medium-term sustainability. view more (2007-10-01)
Study helps clarify role of soil microbes in global warming
Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere. view more (2008-10-29)
MIT researchers explain mystery of gravity fingers
Researchers at MIT recently found an elegant solution to a sticky scientific problem in basic fluid mechanics: why water doesn't soak into soil at an even rate, but instead forms what look like fingers of fluid flowing downward. view more (2008-12-12)
When it comes to forest soil, wildfires pack 1-2 punch
For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure. view more (2008-10-17)
