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)
Before selling carbon credits, read this
Storing carbon in agricultural soils presents an immediate option to reduce atmospheric carbon dioxide and slow global warming. view more (2007-05-21)
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... view more... (2003-05-22)
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)
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)
Columbia geneticists uncover new gene involved in determining hair texture and density in humans
A Columbia University Medical Center research team has discovered a new gene involved in determining hair texture in humans. view more (2008-02-26)
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)
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... view more... (2002-06-18)
Wastewater from the canning industry is not harmful to the agricultural soil
Irrigation with wastewater from the canning industry is not harmful to the quality of agricultural soil and may even, in some cases, improve it. This is the conclusion of Iñigo Abdón Virto Quecedo in his PhD thesis defended at the Public University of Navarre. view more (2004-12-22)
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... 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... view more... (2004-06-10)
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)
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... view more...

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... 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... view more...

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?... view more... (2002-06-26)
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)
Could seaweed clean up DDT?
Adding small amounts of seaweed to contaminated soil could prove to be a natural and effective way of breaking down the toxic pesticide DDT, according to new research in the Journal of Chemical Technology and Biotechnology. A British biologist, Ian Singleton, worked with colleagues in Australia and Thailand to find the right formula to use. Too... view more... (2004-04-13)
Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning
The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood. view more (2005-10-10)
