Measuring Calcium in Serpentine Soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately... view more... (2008-08-20)
Understanding Phosphorus in Soils Is Vital to Proper Management
Phosphorus is one of the key nutrients that can cause algal blooms and related water quality problems in lakes, rivers, and estuaries worldwide. view more (2009-02-05)
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)
Oldest writing in the New World discovered in Veracruz, Mexico
New research published this week in Science details the discovery of a stone (serpentine) block in Veracruz, Mexico, containing a previously unknown system of writing, thought to be the earliest in the New World. view more (2006-09-15)
Finding the Real Potential of No-Till Farming for Sequestering Carbon
The potential of no-tillage (NT) soils for increasing the soil organic carbon (SOC) pool must be critically and objectively assessed. Most of the previous studies about SOC accrual in NT soils have primarily focused on the surface layer (<20-cm soil depth), and not for the whole soil profile. The lack of adequate data on the SOC profile is a... view more... (2008-05-07)
Compost can turn agricultural soils into a carbon sink, thus protecting against climate change
Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions. view more (2008-02-25)
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)
Tracking Poultry Litter Phosphorus: Threat of Accumulation?
The Delmarva Peninsula, flanking the eastern shore of the Chesapeake Bay, is home to some 600 million chickens. The resulting poultry manure and some of the chicken house bedding material is usually composted and then spread onto croplands as a fertilizer. view more (2009-01-29)
Sometimes dry soils yield more clouds
Symposium of the American Meteorological Society in Wageningen (The Netherlands) Cloud formation does not always follow beaten tracks. The formation of low clouds during nice weather conditions will normally take place above moist soils. Under specific atmospheric conditions, which can occur in Europe, drier soils yield more clouds, according to a... view more... (2002-07-12)
Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil. view more (2007-03-13)
Impact of Floods on Soils
A recent study conducted in the Midwestern United States examined the effects of harsh wet conditions on both cultivated and uncultivated soils, vastly advancing the knowledge of water's effects on aggregation. view more (2009-04-09)
Gas-guzzling bacteria
The discovery of a new soil bacterium that consumes methane by oxidising it under atmospheric conditions is reported in Nature, out today. In well-drained soils, these methane-oxidising bacteria can reduce atmospheric levels of methane by 10 per cent. Methane is an important greenhouse gas, and over the last 200 years its concentration in the... view more... (2000-05-10)
Resilient form of plant carbon gives new meaning to term 'older than dirt'
A particularly resilient type of carbon from the first plants to regrow after the last ice age - and that same type of carbon from all the plants since - appears to have been accumulating for 11,000 years in the forests of British Columbia, Canada. view more (2006-11-27)
Where Have All the Students Gone?
Why are the number of students studying soil science as a major declining across the United States? view more (2008-11-04)
Natural Cataclysms Predict Glaciations
Not only geologists are interested in giant canyons of Kursk Magnetic Anomaly, but also soil scientists. There is very convenient place to watch old soils, which earlier were on the surface. As the canyons grew wider, details of ancient landscapes and their changes appear. While studying one of those canyons, Svetlana Sycheva from the Institute of... view more... (2002-01-11)
Geologists recover rocks yielding unprecedented insights into San Andreas Fault
For the first time, geologists have extracted intact rock samples from 2 miles beneath the surface of the San Andreas Fault, the infamous rupture that runs 800 miles along the length of California. view more (2007-10-05)
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)
Decoding mushroom's secrets could combat carbon, find better biofuels & safer soils
Researchers at the University of Warwick are co-ordinating a global effort to sequence the genome of one of the World's most important mushrooms - Agaricus bisporus. view more (2007-07-18)
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...

Nitrous Oxide Emissions Respond Differently to No-Till Depending on the Soil Type
The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but also influence nitrogen dynamics. view more (2008-10-23)
