Will Large Amounts of Soil Carbon be Released to the Atmosphere if Grasslands are Converted to Energy Crops?
Grasslands in the Conservation Reserve Program (CRP) in the United States may be increasingly converted to growing bioenergy grain crops. view more (2009-02-17)
Illinois Soil Nitrogen Test Measures Microbial Nitrogen
Contrary to the prevailing view, cereal crops derive the majority of their nitrogen from the soil, not fertilizer. view more (2009-05-12)
Can biofuels be sustainable?
With oil prices skyrocketing, the search is on for efficient and sustainable biofuels. Research published this month in Agronomy Journal examines one biofuel crop contender: corn stover. view more (2008-08-20)
Erosion rates double along portion of Alaska's coast
Skyrocketing coastal erosion occurred in Alaska between 2002 and 2007 along a 64 kilometer (40 mile) stretch of the Beaufort Sea, a new study finds. The surge of erosion in recent years, averaging more than double historical rates, is threatening coastal towns and destroying Alaskan cultural relics. view more (2009-02-19)
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)
ORNL, Los Alamos pioneer new approach to assist scientists, farmers
Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories. view more (2009-11-20)
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)
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)
Experiment Demonstrates 110 Years of Sustainable Agriculture
A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods. view more (2008-09-30)
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)
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)
Reforestation using exotic plants can disturb the fertility of tropical soils
In many regions of the world, the impact of human activity on the environment intensified considerably over the past century. The high world population growth rate and the expansion of areas given over to crop production associated with climatic changes (longer periods of drought, irregular rainfall patterns) induced by global warming, have... view more...

Expert to Discuss Phosphorus' Impact on Gulf 'Dead Zone'
Phosphorus is an essential element in production agriculture, however fertilizer runoff and wastewater discharge have led to massive eutrophication problems in water bodies worldwide. view more (2009-10-29)
Heavy metals in the Peak District -- evidence from bugs in blanket bogs
Bacteria that consume heavy metals have been found in some of the most contaminated parts of the Peak District in the Southern Pennines and may be changing the pollutants into more toxic forms that could leak out into reservoirs. view more (2008-04-02)
