(PhysOrg.com) -- How much corn crop residue, or stover, can be removed for biofuels without harming soil? An Agricultural Research Service (ARS) study of a 10-mile circle around the University of Minnesota`s Morris campus offers some clues. http://www.physorg.com/news172852191.html Space & Earth Tue, 22 Sep 2009 15:50:05 EST news172852191 The Lost Orphan Mine below the Grand Canyon hasn't produced uranium since the 1960s, but radioactive residue still contaminates the area. Cleaning the region takes an expensive process that is only done in extreme cases, but Judy Wall, a biochemistry professor at the University of Missouri College of Agriculture, Food and Natural Resources, is researching the use of sulfate-reducing bacteria to convert toxic radioactive metal to inert substances, a much more economical solution. http://www.physorg.com/news171643831.html Biology Tue, 08 Sep 2009 16:10:02 EST news171643831 (PhysOrg.com) -- A biochemical analysis of a rare Clovis-era stone tool cache recently unearthed in the city limits of Boulder, Colo., indicates some of the implements were used to butcher ice-age camels and horses that roamed North America until their extinction about 13,000 years ago, according to a University of Colorado at Boulder study. http://www.physorg.com/news154784759.html Other Sciences Wed, 25 Feb 2009 11:46:40 EST news154784759 Imagine a massive international effort to combat global warming by reducing carbon dioxide - build up in the atmosphere. It involves gathering billions of tons of cornstalks, wheat straw, and other crop residue from farm fields, bailing it, shipping the material to seaports, and then burying it in the deep ocean. http://www.physorg.com/news152807537.html Space & Earth Mon, 02 Feb 2009 14:32:37 EST news152807537 (PhysOrg.com) -- Making bales with 30 percent of global crop residues -- the stalks and such left after harvesting -- and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations. http://www.physorg.com/news152384963.html Space & Earth Wed, 28 Jan 2009 17:10:06 EST news152384963 With recent increase in the cost of energy and subsequent explorations into alternative energy sources, the increased harvest of corn residue for cellulosic ethanol production is likely in the future. This may be especially true in fields where corn is grown continuously, in part because perennially high residue amounts favor annual harvests, and also because corn residue left on the soil surface is a source of inoculum for corn diseases. http://www.physorg.com/news150991878.html Space & Earth Mon, 12 Jan 2009 14:11:18 EST news150991878 One of the biggest threats to today's farmlands is the loss of soil organic carbon (SOC) and soil organic matter (SOM) from poor land-management practices. The presence of these materials is essential as they do everything from providing plants with proper nutrients to filtering harmful chemical compounds to the prevention of soil erosion. Sustainable management practices for crop residues are critical for maintaining soil productivity, but being able to measure a loss in the quality of soil can be difficult. http://www.physorg.com/news146314199.html Space & Earth Wed, 19 Nov 2008 10:49:59 EST news146314199 (PhysOrg.com) -- In the rush to develop renewable fuels from plants, converting crop residues into cellulosic ethanol would seem to be a slam dunk. http://www.physorg.com/news135332579.html Space & Earth Tue, 15 Jul 2008 09:22:59 EST news135332579
