(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 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 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
