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)
Is Your Drinking Water Safe?
Lake Bloomington is a major source of drinking water for residents of Bloomington, IL, and has a history of nitrate concentrations that exceed safe levels. Because Lake Bloomington has a record of elevated nitrate levels, local residents are concerned over their drinking water quality. view more (2008-02-29)
Hitchhiking bacteria could compromise the detection of life on Mars
Is there life on Mars? It's possible, but it may not be Martian, say scientists. New research, published in the open access journal BMC Microbiology, suggests that conditions on Mars are capable of supporting dormant bacteria, known as endospores. This raises concern about future attempts to detect Martian life forms because endospores originating... view more... (2003-04-03)
Soil-bound prions that cause CWD remain infectious
Scientists have confirmed that prions, the mysterious proteins thought to cause chronic wasting disease (CWD) in deer, latch on tightly to certain minerals in soil and remain infectious. view more (2006-04-14)
Emphasizing the 'precision' in precision agriculture
New protocol and software developments are helping farmers put the precision back in "precision agriculture" by making it easier for growers to use previously ineffectual soil and environmental data to manage their crops. view more (2007-09-27)
Keeping yields, profits and water quality high
One of the key questions facing agriculturalists in the 21st century is how to produce adequate amounts of food and farm income while protecting environmental quality. view more (2008-05-08)
A computer simulation tool that predicts the influence of forest clearings on soil fertility
The process of clearing consists of cutting down trees in such a way that those remaining have more resources and can grow more. The question was if too many had been cut down, with the concomitant removal of nutrients, and the manner, therefore, in which this process might affect long-term soil fertility. view more (2004-09-08)
Silicon's effect on sunflowers studied
Vibrant, showy sunflowers are revered worldwide for their beauty and versatility. While many varieties of sunflower are grown specifically for their nutritional benefits, ornamental sunflowers have become standards for commercial growers and everyday gardeners. view more (2008-05-08)
Large source of nitrate, a potential water contaminant, found in near-surface desert soils
A UC Riverside-led study in the Mojave Desert, Calif., has found that soils under "desert pavement" have an unusually high concentration of nitrate, a type of salt, close to the surface. Vulnerable to erosion by rain and wind if the desert pavement is disrupted, this vast source of nitrate could contaminate surface and groundwaters,... view more... (2008-03-03)
Overgrazing accelerating soil erosion in northern Mexico
Every year in the world an estimated 20 million hectares of arable land are rendered infertile simply owing to water-induced erosion. view more (2008-01-08)
New Method Confirms Importance of Fungi in Arctic Nitrogen Cycle
A new method to calculate the transfer of nitrogen from Arctic mushrooms to plants is shedding light on how fungi living symbiotically on plant roots transfer vital nutrients to their hosts. view more (2006-05-10)
Detecting synthetic fertilizers: Is it organic or not?
As organic farming becomes more common, methods to identify fraud in the industry are increasingly important. In a recent study in Journal of Environmental Quality, scientists successfully use nitrogen isotopic discrimination to determine if non-organic, synthetic fertilizers were used on sweet pepper plants. view more (2008-02-04)
Climate change triggered dwarfism in soil-dwelling creatures of the past
Ancient soil-inhabiting creatures decreased in body size by nearly half in response to a period of boosted carbon dioxide levels and higher temperatures, scientists have discovered. view more (2009-10-07)
Thawing permafrost a significant source of carbon
Permafrost, permanently frozen soil, isn't staying frozen and a type of soil called loess contained deep within thawing permafrost may be releasing significant, and previously unaccounted for, amounts of carbon into the atmosphere. view more (2006-06-16)
ESA and EADS-CASA sign contract to build instrument for the SMOS mission
A significant milestone in the development of ESA's Soil Moisture and Ocean Salinity (SMOS) mission was reached last week when the contract to build the payload was signed between ESA and EADS (European Aeronautic Defence and Space Company)-CASA from Spain. The contract, worth 62 million euros, was signed in Madrid, Spain on 11 June 2004 at the... view more... (2004-06-17)
Ozone, nitrogen change the way rising CO2 affects Earth's water
Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways. view more (2009-07-10)
Abertay researchers in clover to unearth destructive bug
Scots scientists are playing a key role in a major new research effort which could save Britain's farmers millions of pounds a year through reductions in fertiliser and pesticide use. Biotechnology experts at the University of Abertay Dundee, in partnership with two organisations in England, have been awarded £471,000 by the BBSRC... view more... (2002-04-04)
Warming could free far more carbon from high Arctic soil than earlier thought
Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows. view more (2005-12-06)
