Crop yield can be improved by ensuring adequate nutrient availability. But how should you place the fertilizer and what cropping system gives the best yields? http://phys.org/news253448917.html Biology Thu, 12 Apr 2012 11:29:02 EST news253448917 As the use of biotechnology increases and more companies move forward with the U.S. Environmental Protection Agency's approval to begin full-scale commercialization of seed mixtures in transgenic insecticidal corn, many researchers believe pest monitoring will become even more difficult. http://phys.org/news223819629.html Biology Thu, 05 May 2011 13:07:26 EST news223819629 U.S. Department of Agriculture (USDA) scientists trying to help Florida growers find a replacement for methyl bromide are studying an alternative soil treatment that uses molasses as one of its ingredients. http://phys.org/news219491291.html Space & Earth Wed, 16 Mar 2011 11:10:01 EST news219491291 As the organic food trend continues to grow; more farmers are converting from conventional agriculture to organic production. One of the fastest growing markets in the U.S. is the production of organic milk. The growth of this industry has prompted many farmers to transition their land to organic feed grain production. With transition on the rise, it is necessary for these farmers to have effective and economical organic management practices. http://phys.org/news217601842.html Space & Earth Tue, 22 Feb 2011 12:57:40 EST news217601842 Figuring out how a rice crop was faring used to be a head-scratching exercise with predictably unpredictable results. http://phys.org/news204291497.html Biology Tue, 21 Sep 2010 12:38:31 EST news204291497 Scientists are exploring ways to reduce non-point pollution from agriculture. A new study finds that using straw residue in conjunction with legume cover crops reduces leaching of nitrogen into waterways, but may lower economic return. http://phys.org/news193893203.html Space & Earth Mon, 24 May 2010 04:16:33 EST news193893203 Using productive farmland to grow crops for food instead of fuel is more energy efficient, Michigan State University scientists concluded, after analyzing 17 years' worth of data to help settle the food versus fuel debate. http://phys.org/news190917428.html Space & Earth Mon, 19 Apr 2010 18:10:01 EST news190917428 (PhysOrg.com) -- Agricultural Research Service (ARS) scientists are replicating the effects of climate change to see what the future holds for soybeans, wheat and the soils where they grow. http://phys.org/news180298220.html Space & Earth Thu, 17 Dec 2009 19:10:01 EST news180298220 (PhysOrg.com) -- Curbing greenhouse gas emissions from cultivated fields may require going beyond cutting back on nitrogen fertilizer and changing crop rotation cycles, according to research by Agricultural Research Service (ARS) scientists. http://phys.org/news176575543.html Space & Earth Wed, 04 Nov 2009 17:20:03 EST news176575543 In looking forward to the next Green Revolution, researchers have been carefully examining the role of nitrogen fixation in delivering successful crops around the globe. http://phys.org/news172770598.html Space & Earth Mon, 21 Sep 2009 17:10:39 EST news172770598 Understanding temporal variability in crop yields has implications for sustainable crop production, particularly since greater fluxes in crop yields are projected with global climate change. http://phys.org/news167394662.html Space & Earth Tue, 21 Jul 2009 11:31:52 EST news167394662
