Substrate made from waste glass performs well in greenhouse applications In the greenhouse business, organic and inorganic growing substrates are chosen for the physical and chemical properties necessary to support specific crops and growing conditions. One important physical property in substrates is air-filled pore space, a particularly important characteristic that allows for gas exchange between plants' roots and the outside atmosphere. Perlite and parboiled rice hulls are the two of...

Drought causes peat to release far more carbon dioxide into the atmosphere than has previously been realized Climate change effect on release of CO2 from peat far greater than assumed Drought causes peat to release far more carbon dioxide into the atmosphere than has previously been realized. Much of the world's peatlands lie in regions predicted to experience increased frequency and severity of drought as a result of climate change- leading to the peat drying out and releasing vast...

University of Leicester research into greenhouse gas emissions from oil palm plantations provides robust measures now being used to inform international policies on greenhouse gas emissions A new study on greenhouse gas emissions from oil palm plantations has calculated a more than 50% increase in levels of CO2 emissions than previously thought — and warned that the demand for 'green' biofuels could be costing the earth. The study from the University of Leicester was conducted for...

Concerns that global warming may have a domino effect –unleashing 600 billion tons of carbon in vast expanses of peat in the Northern hemisphere and accelerating warming to disastrous proportions – may be less justified than previously thought. That's the conclusion of a new study on the topic in ACS' journal Environmental Science & Technology. Christian Blodau and colleagues explain that peat bogs – wet deposits of partially decayed plants that are the source of...

Drying of northern wetlands has led to much more severe peatland wildfires and nine times as much carbon released into the atmosphere, according to new research led by a University of Guelph professor. The study, published today in Nature Communications, is the first to investigate the effect of drainage on carbon accumulation in northern peatlands and the vulnerability of that carbon to burning. "Russia, Indonesia and Canada all have abundant peatlands, but they also have been hotspots...

A method of monitoring roots rarely used in wetlands will help Oak Ridge National Laboratory researchers effectively study the response of a high-carbon ecosystem to elevated temperatures and levels of carbon dioxide. Colleen Iversen, ORNL ecosystem ecologist, and an international group of experts, worked to develop a consensus on the use of minirhizotrons, or tiny video cameras that take images of roots, in wetlands. Minirhizotrons are an improvement over previous technology because they...

In the summer of 2008, a lightning strike started a wildfire in eastern North Carolina that burned for weeks, blanketing nearby communities in smoke. An EPA study shows for the first time that smoke from this wildfire, which was fueled by peat (decayed vegetable matter found in swampy areas) can lead to an increase in emergency room visits for both respiratory and cardiovascular effects. This was the first study to report increased visits for symptoms of heart failure in counties exposed to...

KUCHING, Sarawak, Malaysia, March 29, 2011 /PRNewswire/ -- The State Government of Sarawak's Agricultural Policy prioritises sustainable management of biodiversity as part of its strategy for the growth of palm oil plantation. Sarawak has a total land mass of 12.4 million hectares, of which 70% is under forest cover and 14% is secondary forest. 13% of the land is used for agriculture and the remaining 3% compromise settlements and water bodies. Currently the state has allocated 700,000...

University of Alberta researchers have determined that the influence of northern peatlands on the prehistorical record of climate change has been over estimated, but the vast northern wetlands must still be watched closely as the planet grapples with its current global warming trend. Northern peatlands, which are a boggy mixture of dead organic material and water, cover more than four million square kilometers. The largest northern peatlands occur in the subarctic regions of Canada and...

As carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to the atmosphere, report scientists from Indiana University Bloomington and Utrecht University in the Netherlands in an upcoming issue of the Proceedings of the National Academy of Sciences (now online).In a separate paper, also to be published by PNAS, many of the same scientists describe a model...
