Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories. http://www.physorg.com/news177864926.html Space & Earth Thu, 19 Nov 2009 15:20:06 EST news177864926 (PhysOrg.com) -- Researchers have linked poverty in sub-Saharan Africa with poor soil health, but two new Cornell studies find that the recommended practice of applying more fertilizer may not help the poorest farmers. http://www.physorg.com/news173035449.html Space & Earth Thu, 24 Sep 2009 18:36:15 EST news173035449 (PhysOrg.com) -- 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. http://www.physorg.com/news151261782.html Space & Earth Thu, 15 Jan 2009 17:09:42 EST news151261782 Following the Clean Air Act Amendments of 1970 and 1990 acidic deposition in North America has declined significantly since its peak in 1973. Consequently, research has shifted from studying the effects of acidic deposition to the recovery of these aquatic and terrestrial ecosystems. Regional-scale studies have focused primarily on aquatic systems and while many of these ecosystems are showing signs of chemical recovery (increases in acid neutralizing capacity and pH, decreases in sulfate and aluminum concentrations), recovery is slower than expected based on the magnitude of the decline in acid deposition. http://www.physorg.com/news150988084.html Space & Earth Mon, 12 Jan 2009 13:08:04 EST news150988084 Converting forests or fields to biofuel crops can increase or decrease greenhouse gas emissions, depending on where - and which - biofuel crops are used, University of Illinois researchers report this month. http://www.physorg.com/news147443911.html Biology Tue, 02 Dec 2008 12:38:31 EST news147443911 (PhysOrg.com) -- New research shows that we should be looking to the ground, not the sky, to see where climate change could have its most perilous impact on life on Earth. http://www.physorg.com/news146746338.html Space & Earth Mon, 24 Nov 2008 10:52:18 EST news146746338 Earthworms can change the chemical nature of the carbon in North American forest litter and soils, potentially affecting the amount of carbon stored in forests, according to Purdue University researchers. http://www.physorg.com/news144333709.html Space & Earth Mon, 27 Oct 2008 13:41:49 EST news144333709 Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists. http://www.physorg.com/news142675805.html Space & Earth Wed, 08 Oct 2008 09:10:05 EST news142675805
