U.N. Climate Change Conference considers ancient soil replenishment technique in battle against global warming
Former inhabitants of the Amazon Basin enriched their fields with charred organic materials-biochar-and transformed one of the earth's most infertile soils into one of the most productive. view more (2008-12-18)
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)
Agricultural soil erosion not contributing to global warming, study shows
Agricultural soil erosion is not a source of carbon dioxide to the atmosphere, according to research published online in Science. view more (2007-10-26)
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)
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)
Sustainable fertilizer: Urine and wood ash produce large harvest
Results of the first study evaluating the use of human urine mixed with wood ash as a fertilizer for food crops has found that the combination can be substituted for costly synthetic fertilizers to produce bumper crops of tomatoes without introducing any risk of disease for consumers. view more (2009-09-02)
Alternative agricultural practices combine productivity and soil health
The progressive degradation of useful soils for agriculture and farm animal husbandry is a growing environmental and social problem, given that it endangers the food safety of an increasing world population. view more (2009-07-27)
Why Do Autumn Leaves Bother to Turn Red?
Soils may dictate the array of fall colors as much as the trees rooted in them, according to a forest survey out of North Carolina. view more (2007-10-26)
Organic Soils Continue to Acidify Despite Reduction in Acidic Deposition
Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effects of acidic deposition to the recovery of these aquatic and terrestrial ecosystems. view more (2009-01-13)
Shifts in soil bacterial populations 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. view more (2008-11-13)
Urban Trees Enhance Water Infiltration
Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. view more (2008-11-20)
New evidence of early horse domestication
Soil from a Copper Age site in northern Kazakhstan has yielded new evidence for domesticated horses up to 5,600 years ago. view more (2006-10-24)
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)
REDUCTION OF RICEFIELD METHANE EMISSION
Methane (CH4) is considered to be the third most important gas, after carbon dioxide (CO2) and freons, in its contribution to the greenhouse effect and hence to global warming. Cores taken from the ice cap have shown that its concentration in the atmosphere has tripled in 100 years. This figure would explain about 20% of the rise in temperature... view more... (1999-07-07)
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)
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)
Burrowing mammals dig for a living, but how do they do that?
Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones. view more (2007-10-29)
Researchers examine role of soil patterns in dam restoration
Looking at the site today, it's easy to forget that a dam and pond stood for 43 years on the University of Wisconsin-Madison's Franbrook Farm Research Station in southwestern Wisconsin. view more (2008-12-04)
Fungi have a hand in depleted uranium's environmental fate
Fungi may have an important role to play in the fate of potentially dangerous depleted uranium left in the environment after recent war campaigns, according to a new report in the May 6th issue of Current Biology, a publication of Cell Press. view more (2008-05-05)
Cornell Research is Key - New Company Promises to Detoxify Pollutants with Plant Biologicals
A company formed as a spin-off from research conducted at Cornell University, the University of Surrey and the University of Naples, Italy, will provide biological systems that detoxify heavily contaminated soil and water. "Our goal is to develop biological products with broad capabilities for the detoxification of polluted soils or sediments... view more... (2003-04-30)
