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

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)
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... view more... (2003-06-20)
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)
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)
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)
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)
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)
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)
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)
Type of connection procedure after pancreatic surgery influenced rate of pancreatic fistula
After surgery to remove the head of the pancreas, invagination of the pancreas into the small intestine resulted in a lower rate of pancreatic fistula. view more (2009-05-01)
Orchids and fungi -- partners for life
Three Thai orchids have been found to rely on a wide range of fungi to help them take carbon out of the soil instead of producing their own organic carbon. view more (2009-08-14)
Contaminated soil pollution solution: herbicide eating bugs
Cancer-causing soil pollution from herbicide residues may be avoided in future thanks to researchers from Exeter University, who have identified bacteria which can break down a widely used toxic chemical, scientists will announce tomorrow (Thursday, 09 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College... view more...

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)
Soil fungi affect parasitism of foliage-feeding insects
Recent studies have shown the importance of links between soil organisms and those feeding above-ground. However, to date these have involved two or three trophic levels, because it has been assumed that the effects weaken as one progresses up or down a food chain. In a forthcoming paper in Ecology Letters, Gange, Brown & Aplin show that... view more... (2003-11-24)
