TAU's "soil dipstick" forecasts the health of farms, forests and the planet According to climate change experts, our planet has a fever "” melting glaciers are just one stark sign of the radical changes we can expect. But global warming's effects on farming and water resources is still a mystery. A new Tel Aviv University invention, a real-time "Optical Soil Dipstick" (OSD), may help solve the mystery and provide a new diagnostic tool for assessing the health of our planet. According to...

The U.S. National Institute of Standards and Technology has certified three new reference materials for soil testing by laboratories. Officials said the new standard reference materials -- gathered from the San Joaquin Valley in California and from sites near Butte and Helena in Montana -- are designed to aid in determining soil quality, detecting soil contamination and monitoring cleanup efforts from accidental spills or atmospheric deposition. The NIST created its first batch of sample...

An Australian-led team of scientists says it has determined the amount of frozen carbon in Earth's northern regions is more than double previous estimates. We now estimate the deposits contain over 1.5 trillion tons of frozen carbon, about twice as much carbon as contained in the atmosphere, said Charles Tarnocai of Agriculture and Agri-Food Canada, the study's lead author. Pep Canadell, executive director of Australia's Global Carbon Project and study co-author, said the existence of...

DAVIS, Calif., July 7 /PRNewswire-USNewswire/ -- Ten California projects, sponsored by eight partnering organizations, have been selected for funding through the Cooperative Conservation Partnership Initiative (CCPI), a new program established in the 2008 Farm Bill and administered by the USDA's Natural Resources Conservation Service. The projects will receive a targeted portion of the funds available to the Agency through conservation programs such as the Environmental Quality Incentives...

The vast amount of carbon stored in the arctic and boreal regions of the world is more than double that previously estimated, according to a study published this week.The amount of carbon in frozen soils, sediments and river deltas (permafrost) raises new concerns over the role of the northern regions as future sources of greenhouse gases."We now estimate the deposits contain over 1.5 trillion tons of frozen carbon, about twice as much carbon as contained in the atmosphere", said Dr. Charles...

As frozen arctic soil thaws due to climate change, U.S. scientists say bacteria will break down large amounts of carbon, sending it into the atmosphere. Although plants will initially proliferate, nurtured by balmier conditions and an increasing abundance of the greenhouse gas they depend on for growth, University of Florida researchers said they don't expect plant growth will be able to blunt the carbon release. At first, with the plants offsetting the carbon dioxide, it will appear...

"A slow-motion time bomb." That's what one ecologist calls the looming threat of trapped greenhouse gases in the melting Arctic. Ted Schuur, an ecologist from the University of Florida, says the impact of thawing Arctic soil would allow bacteria to slowly break down organic matter and release carbon into the atmosphere, further exacerbating global warming. However, plants will also began to grow more as a result of thawing, which causes researchers to question how much these shrubs will be...

Global warming could result in massive droughts and flooding in Tibet, posing threats to the wellbeing of millions of people, according to the head of the China Meteorological Bureau. According to China's Xinhua news agency, Zheng Guoguang reported on Wednesday that climate change has "accelerated glacial shrinkage, and the melting glaciers have swollen Tibet's lakes." "If the warming continues, millions of people in western China will face floods in the short term and drought in the long...

The Bill & Melinda Gates Foundation and Alliance for a Green Revolution in Africa award $18 million to International Center for Tropical AgricultureResponding 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. This project combines the latest soil science and technology with remote satellite imagery and...

Carbon release from desiccated bogs will speed up the rate of global warming Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change. Such an atmospheric release of even a small percentage of the carbon locked away in the world's peat bogs would dwarf emissions of manmade carbon, scientists at...

Wetland
2013-04-19 18:19:23

A wetland is an area of land that is saturated with water, either permanently or seasonally, such that it takes on the traits of a distinct ecosystem. First and foremost, the factor that distinguishes the wetlands from other land forms or water bodies is the unique vegetation that has adapted to its characteristic soil conditions. The wetland consists mostly of hydric soil, which is supportive of aquatic plants. The water that is found in wetlands can be saltwater, brackish, or freshwater....

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
