Researcher works with European Space Agency to test moisture satellite
Europeans want to peek into our soil and see how dry we are. And an Iowa State University professor is eager to help, and even check their results. view more (2008-04-28)
Where Is Your Soil Water? Crop Yield Has the Answer
Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. view more (2008-07-02)
Mount Cameroon: a natural laboratory for reconstructing soil history
The mechanisms behind rock-weathering processes can provide vital clues for understanding and reconstructing the history of ancient environments and visualizing the physical conditions in which they were formed, especially climatic situations. Thick ancient coverings of weathered material such as laterites are still the most intensively studied to... view more... (2004-10-21)
Satellites Help Map Soil Carbon Flux
Changes in soil carbon occur with changes in land management. Scientists at Oak Ridge National Laboratory and The University of Tennessee investigated quantifying soil carbon changes over large regions. view more (2008-03-26)
Climate change was major factor in erosion of Alps 6 million years ago
The Alps, the iconic rugged mountains that cover parts of seven European nations, might have reached their zenith millions of years ago, some scientists believe, and now are a mere shadow of their former selves. New research offers an explanation. view more (2006-08-16)
Orchids and fungi -- partners for life
Three Thai orchids have been found to rely on a wide range of fungi to help them take carbon out of the soil instead of producing their own organic carbon. view more (2009-08-14)
Contaminated soil pollution solution: herbicide eating bugs
Cancer-causing soil pollution from herbicide residues may be avoided in future thanks to researchers from Exeter University, who have identified bacteria which can break down a widely used toxic chemical, scientists will announce tomorrow (Thursday, 09 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College... view more...

3-D Laser Scanning: A New Soil Quality Measurement
Soil researchers pay close attention to bulk density, as it is one of the most common soil measurements and it is often used as a measure of soil quality. view more (2008-12-04)
Glacial pace of erosion was not so slow, new technique shows
Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work. view more (2005-12-12)
Soil fungi affect parasitism of foliage-feeding insects
Recent studies have shown the importance of links between soil organisms and those feeding above-ground. However, to date these have involved two or three trophic levels, because it has been assumed that the effects weaken as one progresses up or down a food chain. In a forthcoming paper in Ecology Letters, Gange, Brown & Aplin show that... view more... (2003-11-24)
Climate models need deeper roots, scientists say
By soaking up moisture with their roots and later releasing it from their leaves, plants play an active role in regulating the climate. In fact, in vegetated ecosystems, plants are the primary channels that connect the soil to the atmosphere, with plant roots controlling the below-ground dynamics. view more (2005-12-06)
Tillage, Rotation Impacts Peanut Crops
The increasing popularity of reduced tillage on crops has not only been an important development in combating soil erosion, but it has also been associated with increasing organic material and producing high crop yields. view more (2008-11-11)
Getting to the Root of the Matter
Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a root system that makes it all possible. Roots... view more... (2008-08-20)
Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists. view more (2008-10-08)
Without disturbances in nature the world's forests will be impoverished
The forests of the world are not the stable and unchanging ecosystems they have been assumed to be. Without the occurrence of wide-spread disturbances in nature, such as forest fires, icing, or volcanic activity, forests will eventually be impoverished, owing to a lack of phosphorous. This is shown in a study reported in this week's issue of the... view more... (2004-06-21)
Methane found in desert soils bolsters theories that life could exist on Mars
Evidence of methane-producing organisms can be found in inhospitable soil environments much like those found on the surface of Mars. view more (2005-11-01)
NC State Study Finds Better Way to Protect Streams from Construction Runoff
Researchers at North Carolina State University have found an exponentially better way to protect streams and lakes from the muddy runoff associated with stormwater around road and other construction projects. view more (2009-04-20)
As Andean glacier retreats, tiny life forms swiftly move in, CU-Boulder study shows
A University of Colorado at Boulder team working at 16,400 feet in the Peruvian Andes has discovered how barren soils uncovered by retreating glacier ice can swiftly establish a thriving community of microbes, setting the table for lichens, mosses and alpine plants. view more (2008-09-09)
Was Bristol Channel hit by a tsunami?
On the occasion of the 400th anniversary of Britain's largest natural disaster, the author of 2001's prophetic book Tsunami: The Underrated Hazard (Cambridge University Press) reveals strong new evidence that the Bristol Channel was devastated by a tsunami on January 30, 1607. view more (2007-05-01)
Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment in the September 2008 issue of BioScience. view more (2008-09-02)
