Growth in the sea comes down to a struggle for iron

...e growing plants absorb carbon dioxide, a powerful greenhouse gas, he suggested that natural increases in iron inputs to the oceans during the geologic past may have removed enough carbon from the atmosphere to affect global climate, perhaps even contributing to the onset of ice ages. Martin died in 1993 just a...

New research indicates a 'troubled' greenhouse is brewing

...rsity of Oregon geologist's analysis of an ancient greenhouse event. "We know the gathering greenhouse will be warm, but this new information confirms that the contrast between the rainy season and the d...

NASA study finds snow melt causes large ocean plant blooms

...phere, nitrous oxide is 310 times more potent as a greenhouse gas than carbon dioxide. Thus, as very large phytoplankton blooms deplete more oxygen from the water, the creation of nitrous oxide in the Arabian Sea could exacerbate climate change, Goes said. ...

Growth in biomass could put US on road to energy independence

...n foreign oil, a potential 10 percent reduction in greenhouse gas emissions and an improved rural economic picture. Current production of ethanol is about 3.4 billion gallons per year, but that total could reach 80 billion gallons or more under the scenario outlined in this report. Such an increase in ethanol ...

Anammox bacteria produce nitrogen gas in oceans' snackbar

...e anammox process could reduce the emission of the greenhouse gas CO2 during waste water treatment by 88%. Because of these advantages the first large scale waste water treatment system was recently installed in Rotterdam (The Netherlands). Title of publication and authors: Massive nitrogen loss from the Bengu...

Stealth Worms May Improve Insect Pest Control

...g on climate conditions, this method works best on greenhouse ornamentals and vegetables, citrus, cranberry, turfgrass and other crops, rather than on high-acreage crops like cotton and soybeans. "The beauty of this is that in the last 20 years nematodes have been formulated and commercialized," Stock says. "T...

...hland and Amarillo. "We do all of our work in the greenhouse and laboratory," he said. "Here, we have to have an understanding of everything, from the crop growing in the field to the molecular aspects of the pathogen. That makes our program totally unique." Outside research dollars began pouring in and Rush'...

Experiment station researchers to explore genome of disease-fighting fungus

...ed in inducing plant resistance could also aid the greenhouse industry that encounters problems with seedling rot in different plant varieties. "In the nursery industry where you transplant from smaller to larger containers, you can incorporate the fungus as a potting mix amendment that would protect against r...

Grass makes environmentally friendly biofuel

...nvironment because they emit up to 90 percent less greenhouse gases than oil, coal and natural gas do. Furthermore, he says, grass is perennial, does not require fertilization and can be grown on marginal farmland. "Any mixture of grasses can be used, cut in mid- to late summer, left in the field to leach out ...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

Insects develop resistance to engineered crops

...t after 26 generations of the insect living in the greenhouse with single-gene and dual-gene plants housed together, all the plants were eventually damaged by the insects, because over time, greater numbers of insects developed resistance to the plants' toxins. However, in the same two-year time frame, all or a...

Vineyard weeds found to host Pierce's disease of grapes

Sunflower, cocklebur, annual bur-sage, morning glory, horseweed, sacred datura, poison hemlock, and fava bean were most frequently infected. "Our study confirmed that plant species cannot be simply classified as either 'hosts' or 'nonhosts' of...

Errors in the measurement of global warming corrected

...face warming has partly resulted from a buildup of greenhouse gases in the atmosphere. The key to the error in climate change estimates lay in instrument design, according to this study. With exposed sensors, measurement taken in daylight read too warm, and while solar heating had a measurable impact on the ea...
