New-Caledonia: is the chromium present in soil toxic for crop plants ?
Nearly one-third of the surface area of New Caledonia bears outcrops of ultramafic rocks containing high levels of heavy metals, such as nickel and chromium. The soils derived from these formations, bearing high concentrations of these metals, are however poor in mineral elements essential for plant growth, like nitrogen, phosphorus, carbon and... view more...

New bug to tackle pollution
A new, all-natural, pollutant-busting microbe has been discovered by scientists in Germany. Research published in the October 2003 issue of Microbiology, a Society for General Microbiology journal, describes a new strain of bacterium, which could be used in the near future to clean up polluted land. Over the years, many harsh and highly toxic... view more... (2003-10-10)
Soil nutrition affects carbon sequestration in forests
On December 11, USDA Forest Service (FS) scientists from the FS Southern Research Station (SRS) unit in Research Triangle Park, NC, along with colleagues from Duke University, published two papers in The Proceedings of the National Academy of Science (PNAS) that provide a more precise understanding of how forests respond to increasing atmospheric... view more...

Some plants may compensate for herbivore damage by stimulating nutrient release in the soil
Browsing by mammals often has a serious impact on the growth of tree saplings and the regeneration of forests. However, there is much uncertainty with regard to effects on soil nutrient cycling and in turn, potential consequences for the growth of plants. In a paper to be published in the June issue of Ecology Letters, researchers from Lancaster... view more... (2004-05-13)
Are the Alps growing or shrinking?
The Alps are growing just as quickly in height, as they are shrinking. This paradoxical result could be proven by a group of German and Swiss geoscientists. view more (2009-11-06)
Dried mushrooms slow climate warming in Northern forests
The fight against climate warming has an unexpected ally in mushrooms growing in dry spruce forests covering Alaska, Canada, Scandinavia and other northern regions, a new UC Irvine study finds. view more (2008-11-03)
Special topics in environmental mechanics
With rapid development of economics since the 1980s, people have been increasingly realized that the environment plays an important role in the sustainable development of society and economy. view more (2008-07-01)
Rerouting of Major Rivers in Asia Provides Clues to Mountains of the Past
Scientists have long recognized that the collision of the earth's great crustal plates generates mountain ranges and other features of the Earth's surface. view more (2005-12-27)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)
Exotic timber plantations found to use more than twice the water of native forests
Ecologists have discovered that timber plantations in Hawaii use more than twice the amount of water to grow as native forests use. view more (2009-09-16)
Study explores plant phenotypic plasticity belowground
When we think of organisms actively searching for resources (foraging) we generally think of things like wolves stalking elk or butterflies finding flowers. Why don't we also think about plants growing roots through the soil? view more (2005-07-27)
Global warming predictions are overestimated, suggests study on black carbon
A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions. view more (2008-11-20)
Ammonia-loving archaea win landslide majority
A genetic analysis of soil samples indicates that a group of microorganisms called crenarchaeota are the Earth's most abundant land-based creatures that oxidize ammonia. view more (2006-08-17)
Many characteristics of Mars, including ice, are similar to Earth, paper says
Mars gets as far as 250 million miles away, but many parts of it closely resemble places on Earth, including its landscape, history of water, soil and even its weather, says a Texas A&M University researcher in the current issue of "Science" magazine. view more (2009-07-06)
New digital map of Africa's depleted soils to offer insights critical for boosting food production
Responding to sub-Saharan Africa's soil health crisis, the International Center for Tropical Agriculture (CIAT) announced today an ambitious new effort to produce the first-ever, detailed digital soil map for all 42 countries of the region. view more (2009-01-13)
Some biofuels might do more harm than good to the environment, study finds
Biofuels based on ethanol, vegetable oil and other renewable sources are increasingly popular with government and environmentalists as a way to reduce fossil fuel dependence and limit greenhouse gas emissions. view more (2008-05-28)
Physical fertility of typical Mekong delta soils (Vietnam) and land suitability assessment foralternative crops with rice cultivation
Most of the soils in the Mekong delta, Vietnam are formed and developed during the Holocene period. The first Viet people came to reclaim and exploit this plain at the beginning of the 17th century. As a result, in the middle of the 19th century, the Mekong delta had become the largest region of agricultural production, essentially rice produce... view more... (2002-11-27)
Exalted status for the humble earthworm
In the week following the Earth Summit in Johannesburg, international attention will be focused on Cardiff and the ecological importance of earthworms in temperate and tropical ecosystems. Considered sacred by Cleopatra, earthworms undoubtedly promote the sustainability of soils. The earthworm's status as one of the world's most crucial organisms... view more... (2002-08-28)
Cranfield University Rolls onto the Cricket Pitch
The England and Wales Cricket Board (ECB) has provided funding to Cranfield University's Centre for Sports Surfaces at Silsoe, which has launched a new research programme to look at ways to improve cricket pitch performance from the village green up to the test arena. This funding will create an Engineering and Physical Sciences Research Council... view more... (2003-06-26)
Do moles provide the answer for cost effective drainage?
Cranfield University's Centre for Sports Surfaces, together with TurfTrax Ground Management Systems Ltd, has won a £62.5K research grant from the Football Foundation to undertake research into alternative pitch drainage methods for winter sports pitches on heavy clay soils. The research, being conducted at Cranfield University's Silsoe... view more... (2004-08-19)
