An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon costs. Mycorrhizae can structure plant communities... View More (2003-05-22)
No-till farming improves soil stability
A joint Agricultural Research Service (ARS)-multi-university study across the central Great Plains on the effects of more than 19 years of various tillage practices shows that no-till makes soil much more stable than plowed soil. View More (2010-05-12)
Estimate Soil Texture-by-Feel
The ability to estimate soil texture-by-feel is an important skill that students and registered soil scientists should learn. View More (2008-10-16)
Spreading antibiotics in the soil affects microbial ecosystems
Antibiotics used extensively in intensive livestock production may be having an adverse effect on agricultural soil ecosystems. View More (2009-03-30)
Fingerprinting Fugitive Dust
Each community of soil microbes has a unique fingerprint that can potentially be used to track soil back to its source, right down to whether it came from dust from a rural road or from a farm field, according to a U.S. Department of Agriculture (USDA) soil scientist. View More (2011-07-22)
Dust storms may carry bacteria to Japan from China
Bacteria found in soil around Tokyo are not indigenous to the area. A study published in the open access journal Saline Systems reveals a large proportion of salt-loving bacteria in non-saline soil around Tokyo. The researchers suggest that dust storms may have carried the bacteria from their natural habitats in China. View More (2005-10-20)
Students Get a Feel for Soil-Water Relationships
Using little more than PVC rings, a trashcan, and a scale, students can literally get a feel for soil water retention and field capacity, concepts that are important and useful in fields from farming to engineering. View More (2010-08-02)
The effect of transgenic nematode resistance on non-target organisms in the potato rhizosphere
A paper published today in the December Issue of Journal of Applied Ecology by Cowgill et al describes the results of small-scale field trials that were used to assess the effect of PI-expressing potatoes on non-target soil organisms. The impact of a currently used PCN management option, the nematicide, aldicarb, on soil organisms was also studied. View More (2002-11-26)
Experts support call for new focus on soil management
Professor Mark Kibblewhite, Director of the recently launched National Soil Resources Institute, today strongly supported calls by the Environment Agency for a new focus on environmentally-friendly soil management practices. This comes after publication by the Agency of a report on Agriculture and Natural Resource Problems. NSRI is a department on Cranfield University’s Silsoe campus, and a... View More (2002-06-18)
Glass fibre predicts uptake in earthworms
Dutch researchers have discovered that glass fibres absorb the same types and quantities of toxic substances from damp soils as earthworms, which form the basis of the current methods soil researchers use for toxicity analyses. The Institute for Inland Water Management and Waste Water Treatment (Dutch acronym: RIZA) now uses glass fibres to measure water pollution and sediment pollution.... View More (2003-06-24)
Manipulating biotope space can enhance beneficial biodiversity effects
Using diverse plant mixtures instead of monocultures can increase yield and other ecosystem goods and services on which humans depend. Recent studies showed that such beneficial effects of biodiversity depend on complementarity between species in resource use, as is the case if species root in different soil depths. This knowledge led to the further hypothesis that the biotope space, for example... View More (2004-06-10)
Final FACE harvest reveals increased soil carbon storage under elevated carbon dioxide
Elevated carbon dioxide concentrations can increase carbon storage in the soil, according to results from a 12-year carbon dioxide-enrichment experiment at Oak Ridge National Laboratory. View More (2012-03-06)
New Sighting of Soil-Borne Wheat Mosaic Virus (SBWMV)
Following investigation of a sample sent to NIAB and Central Science Laboratory (CSL), two new sites in Kent have been identified with soil-borne wheat mosaic virus (SBWMV). The virus was identified in the UK in Wiltshire for the first time in 1999 and this occurrence appears to have no connection with the Wiltshire site. The work is part of a NIAB / HGCA project, with collaboration from CSL, on... View More (2000-08-08)
Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them into the atmosphere as carbon dioxide. This will lead to further increases in global temperatures. View More (2005-05-05)
With 3 new reference materials, NIST gets the dirt on soil
The National Institute of Standards and Technology (NIST) has issued three new certified reference materials for soil. Intended for use as controls in testing laboratories, the new Standard Reference Materials (SRMs)-gathered from the San Joaquin Valley in California and from sites near Butte and Helena in Montana-will aid in determining soil quality, detecting soil contamination, and monitoring...

Invititation to the Media - Soils as carbon sinks-a breathing space in the race against global warming?
Can we use land carbon sinks as a way to buy time for the restructuring of our energy generation? "We estimate soil carbon sinks could mitigate 8% of the EU`s emissions if major changes were made in land use and agricultural management ," says Professor David Powlson of IACR Rothamsted. However; How many of the land-use options are practicable? How can we tell if someone is cheating on their... View More (2002-06-26)
Can One-time Tillage Improve No-till?
A one-time tillage has no adverse effects on yield or soil properties on no-till land, according to field research conducted at the University of Nebraska-Lincoln. Although tillage is another expense for farmers and generally increases the risk of soil erosion, a one-time tillage may be performed to correct some problem, such as a perennial weed problem.

Describing Soils: Calibration Tool for Teaching Soil Rupture Resistance
A new calibration tool was recently developed to help students and soil scientists calibrate their thumb and forefinger for the correct amount of pressure. View More (2009-01-06)
Managing Soil Copper in Crops Irrigated with Cattle Footbath Wastewater
Getting a head start on stopping soil copper buildup will now be a bit easier, thanks to studies by U.S. Department of Agriculture (USDA) scientists. View More (2012-09-25)
Rethinking connection between soil as a carbon reservoir and global warming
Soils store three times as much carbon as plants and the atmosphere. Soil organic matter such as humus plays a key role in the global carbon cycle as it stores huge amounts of carbon and thus counters global warming. View More (2011-10-06)
