Voicemail discovered in nature
Insects can use plants as 'green phones' for communication with other bugs. A new study now shows that through those same plants insects are also able to leave 'voicemail' messages in the soil. View More (2012-06-13)
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)
Answering that age-old lament: Where does all this dust come from?
Where does it come from? Scientists in Arizona are reporting a surprising answer to that question, which has puzzled and perplexed generations of men and women confronted with layers of dust on furniture and floors. View More (2009-10-29)
Grazing of Cattle Pastures Can Improve Soil Quality
A team of U.S. Department of Agriculture (USDA) scientists has given growers in the Piedmont guidance on how to restore degraded soils and make the land productive. Researchers with the USDA's Agricultural Research Service (ARS) found that if cattle are managed so that they graze moderately, soil quality can be restored and emissions of carbon dioxide (a greenhouse gas) can be reduced.

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.

Tropical Soils Impede Landmine Detection
Use of a metal detector is the most common technique when searching for landmines, which litter the soil in approximately 90 countries around the world. Many of these countries are located in the tropics where intensively weathered soils are prevalent. View More (2008-02-07)
Agriculture of Conservation proves to be best for cereal crops in Navarre
The application of conservation agriculture techniques to cereal crops in the semiarid zones of Navarre-57% of the surface area given over to crop cultivation in Navarre, is most profitable for conventional agriculture and improves the quality of the soil, apart from contributing to the sustainability of the environment.

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)
How much nitrogen is too much for corn?
North Carolina State researchers recently discovered a test that quickly predicts nitrogen levels in the humid soil conditions of the southeastern United States. View More (2007-04-24)
Wayne State study shows airborne dust in urban areas impacts lead levels in children
A team of researchers led by Shawn P. McElmurry, Ph.D., P.E., assistant professor of civil and environmental engineering in Wayne State University's College of Engineering, has confirmed that seasonal fluctuations in blood lead levels found in children in urban areas throughout the United States and elsewhere in the northern hemisphere are the result of resuspended dust contaminated with lead.

The Sweet World of Soil Microbiology
Using classroom, hands-on activities can help instructors to communicate difficult scientific concepts and stimulate student thinking. Despite its importance, the diversity in soil microbes can conceptually be difficult to teach, especially in natural resource classrooms composed primarily of undergraduates who have had little exposure to microbiology. That's where the candy comes into play. View More (2008-05-01)
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 atmosphere has doubled. But, until now, its low levels... View More (2000-05-10)
Cranfield Digs Deep Into The Insurance Market
Cranfield University's commercial arm, Silsoe Ventures Ltd (SVL), has launched a unique Natural Perils Directory, which integrates soil, climate and other environmental data, onto the insurance market. The directory, which is available on CD-ROM and is compatible with leading GIS and database packages, has been specifically developed from Cranfield University's National Soil Map which has the...

Nitrogen Applied
Combating soil erosion is a primary concern for agricultural producers in the United States, and many have incorporated conservation tillage systems in their effort to maintain a profitable crop output. View More (2008-10-02)
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 hindrance to conclusively ascertain the effects of... View More (2008-05-07)
Conventional plowing is 'skinning our agricultural fields'
Traditional plow-based agricultural methods and the need to feed a rapidly growing world population are combining to deplete the Earth's soil supply, a new study confirms. View More (2007-08-09)
Mustard - hot stuff for natural pest control
Researchers, growers and Industry specialists from 22 countries will share the latest research into the use of Brassica species, such as mustard, radish, or rapeseed, to manage soil-borne pests and weeds - a technique known as biofumigation. View More (2008-07-28)
Study Finds Greenhouse Gas Reduction Strategy May Be Safe for Soil Animals
A new study has found that an emerging tool for combating climate change may cause less harm to some soil animals than initial studies suggested. View More (2011-06-02)
Changing climate will lead to devastating loss of phosphorus from soil
Crop growth, drinking water and recreational water sports could all be adversely affected if predicted changes in rainfall patterns over the coming years prove true, according to research published this month in Biology and Fertility of Soils. View More (2009-04-15)
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)
