Cornell researchers clone aluminum-tolerance gene in sorghum, promising boost to crop yields in developing world
When soils are too acidic, aluminum that is locked up in clay minerals dissolves into the soil as toxic, electrically charged particles called ions, making it hard for most plants to grow. In fact, aluminum toxicity in acidic soils limits crop production in as much as half the world's arable land, mostly in developing countries in Africa, Asia and... view more... (2007-08-28)
Declining snowpack cools off CO2 emissions from winter soils, says U. of Colorado study
A recent decrease in Rocky Mountain snowpack has slowed the release of heat-trapping carbon dioxide gases from forest soils into the atmosphere during the dead of winter. view more (2006-02-09)
New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate. view more (2007-12-12)
"Nanominerals" Influence Earth Systems from Ocean to Atmosphere to Biosphere
The ubiquity of tiny particles of minerals--mineral nanoparticles--in oceans and rivers, atmosphere and soils, and in living cells are providing scientists with new ways of understanding Earth's workings. Our planet's physical, chemical, and biological processes are influenced or driven by the properties of these minerals. view more (2008-03-24)
Great wines come from great soils
The world's greatest wines are the result of a threefold synergy among grape variety, human input, and something called the "terroir" -- a term often defined as the vineyard site, soil, and climate. view more (2009-11-04)
XIVth International Colloquium on Soil Zoology and Ecology
Soils provide humans with a whole range of irreplaceable ecosystem services the production and maintenance of which are largely dependent on the actions of the animal communities which inhabit them. Apart from the substantial agricultural production made necessary by humanity's demand for food, soils filter and store water, holding back erosion... view more... (2004-08-30)
Superscanner helps scientists see into the unknown
Researchers at The University of Nottingham have a new weapon in their arsenal of tools to push back the boundaries of science, engineering, veterinary medicine and archaeology. view more (2009-09-11)
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)
Study Reveals that Nitrogen Fertilizers Deplete Soil Organic Carbon
The common practice of adding nitrogen fertilizer is believed to benefit the soil by building organic carbon, but four University of Illinois soil scientists dispute this view based on analyses of soil samples from the Morrow Plots that date back to before the current practice began. view more (2007-10-30)
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)
Preventing Soil Erosion in Continuous Corn
With recent increase in the cost of energy and subsequent explorations into alternative energy sources, the increased harvest of corn residue for cellulosic ethanol production is likely in the future. view more (2009-01-13)
Nottingham centre to help UK to meet its carbon targets
Cutting-edge technology that 'captures' polluting carbon dioxide and stores it permanently inside rocks will be developed at a new £1.1m research centre at The University of Nottingham. view more (2007-07-30)
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...

Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide view more (2006-04-13)
Scientists: As rainfall changes, tropical plants may acclimate
Tropical plants may be more adaptable than commonly thought to changing rainfall patterns expected to accompany a warming climate, new research shows. view more (2007-05-08)
Wind, Salt, and Water Are Leading Indicators of Land Degradation in Abu Dhabi
Desert environments are characterized by poor vegetative cover, strong winds, dry, non-cohesive sandy soils, and hyper-arid conditions. view more (2009-05-07)
Landfill Cover Soil Methane Oxidation Underestimated
Landfilled waste decomposes in the absence of oxygen and results in the production of methane. Landfills are classified as the second-largest human-made source of CH4 in the U.S. Additionally, landfill gas contains numerous non-methane hydrocarbons that are either volatilized directly from waste materials or produced through biochemical reactions... view more...

New digital map of Africa's depleted soils to offer insights critical for boosting food production
Responding to sub-Saharan Africa's soil health crisis, the International Center for Tropical Agriculture (CIAT) announced today an ambitious new effort to produce the first-ever, detailed digital soil map for all 42 countries of the region. view more (2009-01-13)
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)
Healthy rocks and wildlife farming
The relationship between rocks and our health, and new methods for farming and countryside management to both encourage wildlife and make a profit, are just two of the exciting research projects highlighted in the latest issue of Planet Earth, the quarterly journal of the Natural Environment Research Council (NERC). The rock diet Rocks are a vital... view more... (2002-10-23)
