Adapting agricultural practices to reduce the greenhouse effect
More than one-third of the greenhouse gases emitted into the atmosphere stem from agriculture and forestry. One of the current concerns is to find ways of managing agriculture differently in order to increase the level of carbon storage in soils and limit emission of gases that contribute to global... view more (2004-11-23)

Study helps clarify role of soil microbes in global warming
Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere.   view more (2008-10-29)

"Facts needed, not just opinions": Risk assessment research initiated to determine effects of genetically modified plants on soil ecosystems
Do genetically modified plants present a risk to the environment? "Most of the arguments used both in support and against the use of genetically modified crops to date have not been based upon facts, but rather emotion," claims George Kowalchuk of the Netherlands Institute of Ecology... view more (2001-06-11)

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)

Iowa State researchers developing wireless soil sensors to improve farming
Ratnesh Kumar keeps his prototype soil sensors buried in a box under his desk. He hopes that one day farmers will be burying the devices under their crops.   view more (2008-10-13)

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... view more (2005-11-29)

Urban Trees Enhance Water Infiltration
Global land use patterns and increasing pressures on water resources demand creative urban stormwater management.    view more (2008-11-20)

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... view more (2008-05-01)

At the root of nutrient limitation, ecosystems are not as different as they seem
Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns - eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are "hot-dog limited" - the extra buns are worthless without hot... view more (2007-11-09)

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)

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... 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... view more (2003-06-20)

Yale study offers new paradigm on ecosystem ecology
Predators have considerably more influence than plants over how an ecosystem functions, according to a Yale study published today in Science.   view more (2008-02-15)

Potassium limitation, ammonium toxicity and amino acid excretion in yeast
As a single-celled eukaryote organism, the yeast strain S. cerevisiae has some limitations in terms of how it can be used as a model for more complex multicellular eukaryotes.   view more (2006-10-17)

Healthy rivers needed to remove nitrogen
Healthy streams with vibrant ecosystems play a critical role in removing excess nitrogen caused by human activities, according to a major new national study published this week in Nature.   view more (2008-03-13)

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.... view more (2008-05-07)

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)

Scientists a step closer to producing fuel from bacteria
Scientists at the University of Sheffield have shown how bacteria could be used as a future fuel. The research, published in the journal Bioinformatics, could have significant implications for the environment and the way we produce sustainable fuels in the future.   view more (2008-08-07)

Catalytic converter gets the pollution out of diesel engines
In the near future the usual summer ozone peaks exceeding the allowed threshold may be a thing of the past: the Paul Scherrer Institute (PSI) in Switzerland has developed a new type of catalytic conversion system, which filters nearly all nitrogen oxides out of diesel exhaust gases using a refined... view more (2004-09-08)

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)

Where Is Your Soil Water? Crop Yield Has the Answer
Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots.   view more (2008-07-02)

Low levels of contamination also influence mortality rate
Navarre doctor Rosa Mar'­a Al'¡s Brun has shown, in her PhD thesis defended at the Public University of Navarre, that, despite contamination rates in Pamplona being very low, these still have an influence on death rates.   view more (2004-08-20)

Invasive species alter habitat to their benefit
When scientists study habitats that alien species have invaded, they usually find predictable patterns. The diversity of native species declines, and changes occur in natural processes such as nutrient cycling, wildfire frequency and the movement of water through the system.   view more (2006-08-10)

Nature's process for nitrogen fixation caught in action
Nitrogen gas is converted to ammonia fertilizer by a chemical process that involves high temperature and high pressure. Nature does the same thing at ambient temperature and pressure. The process, called nitrogen fixation, is essential to life as it provides nutrients to plant life.   view more (2006-11-10)

Satellites Help Map Soil Carbon Flux
Changes in soil carbon occur with changes in land management. Scientists at Oak Ridge National Laboratory and The University of Tennessee investigated quantifying soil carbon changes over large regions.   view more (2008-03-26)
