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)
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)
Researchers to determine if aeration reduces compaction, runoff on no-till fields
Much of Texas' wheat may be grazed as a part of a dual-use crop. But many fields are still prepared using conventional tillage, which may not efficiently capture rainfall - a key to economic success in a semi-arid environment, said a Texas AgriLife Research scientist. view more (2009-04-02)
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)
Prairie soil organic matter shown to be resilient under intensive agriculture
A recent study has confirmed that although there was a large reduction of organic carbon and total nitrogen pools when prairies were first cultivated and drained, there has been no consistent pattern in these organic matter pools during the period of synthetic fertilizer use, that is, from 1957-2002. view more (2009-01-16)
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)
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)
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)
Soil Carbon Storage is Not Always Influenced by Tillage Practices
The practice of no-till has increased considerably during the past 20 yr. Soils under no-till usually host a more abundant and diverse biota and are less prone to erosion, water loss, and structural breakdown than tilled soils. view more (2009-02-26)
A win-win: U-pick pumpkin farms recycle urban leaves
Americans love pumpkins. The growing popularity of rural fall festivals, grade school farm tours, and "u-pick" pumpkin farms has resulted in an increase in consumer demand for pumpkins throughout the country. view more (2008-12-29)
Researchers Find That Cattle Tuberculosis Remains in Fields For Up to 4 Months
Researchers from the University of Warwick's Department of Biological Sciences have found evidence that bovine tuberculosis remains in fields for up to 4 months. This means that long after an outbreak of bovine TB on a farm healthy cattle may still be exposed to the disease from pasture that had been used by infected cows any time in the previous... view more...

Groundbreaking research in Scotland
A £5.85 million pound study of the soil in the Cheviot Hills has finally come to an end, producing a huge wealth of new information for scientists. view more (2004-03-31)
Long-term study of orchard ground cover management systems
Orchard floor and groundcover management is important to fruit growers, affecting the efficiency of orchard operations, fruit tree performance, and soil quality. view more (2009-02-27)
More market less poverty, but also more sustainable land use?
During empirical research in Benin, Dutch-sponsored researcher Esa√Ře Gandonou demonstrated that farmers in underdeveloped parts of developing countries make little extra effort to control soil erosion if the market to which they sell their products becomes more accessible. view more (2006-02-16)
Scientists find stem cell switch
Scientists have discovered how plant stem cells in roots detect soil structure and whether it is favourable for growth. view more (2007-07-27)
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)
Pathogenic soil bacterium is influenced by land management practices
Researchers from Menzies School of Health Research in Darwin, Australia have found that the soil bacterium Burkholderia pseudomallei, which causes the emerging infectious disease melioidosis in humans and animals, is associated with land management changes such as livestock husbandry or residential gardening. view more (2009-01-21)
Radioactive waste – no problem for metal-munching bacteria
A harmless soil bacterium, which can survive high-level exposures to gamma radiation, is being developed to clean up land contaminated with radioactive waste, experts heard today (Wednesday 12 September 2001) at the bi-annual meeting of the Society of General Microbiology at the University of East Anglia. US government researcher Dr. Michael Daly... view more... (2001-09-07)
Finding the key to a healthy environment
It is often said that "you are what you eat", but how far is your health affected by where you live? It has been known for some time that an excess (or deficiency) of a particular element in the local soil or water can cause illness, often exacerbated in communities that depend on locally grown produce. Local pollution also constitutes a health... view more... (2001-03-12)
