Amazonian terra preta can transform poor soil into fertile

...rary soil management also can reduce environmental pollution by decreasing the amount of fertilizer needed, because the bio-char helps retain nitrogen in the soil as well as higher levels of plant-available phosphorus, calcium, sulfur and organic matter. The black soil also does not get depleted, as do other s...

York researchers develop pollution-busting plants to clean up contaminated land

...gy, Decades of military activity have resulted in pollution of land and groundwater by explosives resistant to biological degradation. Large tracts of land used for military training, particularly in the USA, are contaminated by RDX, one of the most widely-used explosives, which is both highly toxic and carc...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

...es. Global atmospheric mapping of nitrogen dioxide pollution performed by ERS-2's GOME and Envisat's SCIAMACHY reveals the world's largest amount of NO2 hanging above Beijing and northeast China, as reported in Nature this week. As part of ESA's Dragon Programme, European and Chinese researchers are using res...

NASA satellite data provides rapid analysis of Amazon deforestation

... for farming result in large fires that create air pollution and release tiny particles, known as aerosols. Aerosols can both heat and cool the air, depending on size, shape and color. Building on the results of this study, Brazil's INPE has developed a near or almost real time monitoring application for defo...

A radical solution for environmental pollution

...re very difficult to degrade, which is why they're pollution hazards." Toluene is especially worrisome because it's more soluble in water than most organic compounds are, which means that it can contaminate groundwater. Bacteria such as T. aromatica hold promise for use in cleaning up environmental pollutants...

Study uncovers dirty little secret: Soil emissions are much-bigger-than-expected component of air pollution

...d play a substantially larger role in seasonal air pollution than previously believed. Nitrogen oxide emissions total more than 40 million metric tons worldwide each year, with 64 percent coming from fossil fuel combustion, 14 percent from burning and a surprising 22 percent from soil, said Lyatt Jaeglé, a UW...

Pollution-eating bacteria produce electricity

Microbiologists seeking ways to eliminate pollution from waterways with microbes instead discovered that some pollution-eating bacteria commonly found in freshwater ponds can generate electricity. They present their findings today at the 105th General Meeting of the American Society for Microbiology. ...

Organic farms produce same yields as conventional farms

...nic farming reduced local and regional groundwater pollution by not applying agricultural chemicals. Pimentel noted that although cash crops cannot be grown as frequently over time on organic farms because of the dependence on cultural practices to supply nutrients and control pests and because labor costs av...

Study shows eutrophic lakes may not recover for a millennium

...ter's model also shows that, unchecked, phosphorus pollution could put Lake Mendota on a fast track to extreme degradation. "There is a potential shift to an extremely degraded state that could occur even if we shut off the phosphorus tomorrow. It would have water quality as bad as the worst lakes in the world...
