Replacing corn with perennial grasses improves carbon footprint of biofuels
Converting forests or fields to biofuel crops can increase or decrease greenhouse gas emissions, depending on where - and which - biofuel crops are used, University of Illinois researchers report this month. view more (2008-12-03)
Scientists find grass yield, carbon storage not affected by creepy-crawlies in the soil
New results from experiments at a unique ecology facility show that plant communities are dramatically altered by changes to the type of animal species living among their roots, but that key ecosystem measurements such as overall agricultural yield or the amount of soil carbon stored are unaffected. According to the results of a three year study... view more... (2002-10-18)
Compost can turn agricultural soils into a carbon sink, thus protecting against climate change
Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions. view more (2008-02-25)
Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate that plant genes can have strong effects on the... view more...

Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the rate of global warming to increase further. view more (2006-03-09)
Improving China's acid rain control strategy
Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution control program will be largely offset by increases in nitrogen emissions, which the country's current policy largely... view more...

Adapting agricultural practices to reduce the greenhouse effect
More than one-third of the greenhouse gases emitted into the atmosphere stem from agriculture and forestry. One of the current concerns is to find ways of managing agriculture differently in order to increase the level of carbon storage in soils and limit emission of gases that contribute to global atmospheric warming. view more (2004-11-23)
OJ Worse for Teeth than Whitening, Says Eastman Institute for Oral Health Researchers
With the increasing popularity of whitening one's teeth, researchers at the Eastman Institute for Oral Health, part of the University of Rochester Medical Center, set out to learn if there are negative effects on the tooth from using whitening products. view more (2009-07-01)
The Raining Champions
A better understanding of the ground beneath our feet may be the key to improved seasonal weather forecasts, say an international team of environmental scientists in the journal Science today. Researchers investigating the impact of soil moisture on rainfall have found that, across the globe, there are at least three hotspots where rainfall seems... view more... (2004-08-19)
The MARSIS radar estimates the volume of water in the south pole of Mars
By studying the South Polar region of Mars, the MARSIS (Mars Advanced Radar for Subsurface and Ionospheric Sounding) radar of the Mars Express space probe has enabled the structure of the layered deposits of this region to be elucidated. view more (2007-04-02)
Drink brewed tea to avoid tooth erosion
Today, the average size soft drink is 20 ounces and contains 17 teaspoons of sugar. More startling is that some citric acids found in fruit drinks are more erosive than hydrochloric or sulfuric acid-which is also known as battery acid. view more (2008-11-26)
Predicting the species diversity of large herbivores in nature reserves
The number of species of large herbivores that can live in a nature reserve can be easily calculated using just rainfall and soil fertility data. The Wageningen ecologist Dr Han Olff can use this to indicate on a worldwide basis where nature reserves that protect large mammals are needed. On a map of the world, the researcher from Wageningen... view more... (2002-02-19)
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... view more...

Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil. view more (2007-03-13)
Complex carbon picture clearer
Study shows that more plant litter resulting from higher CO2 could boost the amount of carbon released into the atmosphere. view more (2007-12-12)
Permafrost Threatened by Rapid Retreat of Arctic Sea Ice, NCAR Study Finds
The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR). view more (2008-06-11)
Help Students Think like Soil Scientists
Emphasizing cross-disciplinary concepts in teaching soil science courses, such as mass-volume relationships, can help undergraduates learn real-world, problem-solving skills that are crucial to their success in soil science careers. view more (2009-09-29)
Modelling To Develop European Sand Dredging Guidelines
Computer predictions of the effects of commercial sea-sand dredging on coastal erosion, produced by an international team headed by Dr Alan Davies of the University of Wales, Bangor`s School of Ocean Sciences, will play a key role in developing new European Guidelines for siting commercial sand dredging activities. Increased demand for North Sea... view more... (2002-08-07)
Scientists Map Soils on an Extinct American Volcano
Union County New Mexico is a landscape of striking diversity. Out of expansive rangelands rise sporadic yet majestic cinder cone volcanoes and mesas preserved by basalt, part of the Raton-Clayton Volcanic Field. Capulin volcano, formed approximately 62,000 years ago, is the youngest volcano in the field. view more (2008-10-21)
Soybean varieties viable in southern Indiana, resistant to root-knot nematode
Purdue University researchers have identified several soybean varieties that grow well in areas of the Midwest like southern Indiana and are resistant to root-knot nematodes, a plant-destroying parasite with a recently confirmed presence in that part of the state. view more (2008-03-24)
