Fortified by Global Warming, Deadly Fungus Poisons Corn Crops, Causes Cancer
2013-01-15 18:20:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Last years drought increased the spread of a carcinogenic mold called aspergillus (Aspergillus flavus), a fungal pathogen that poisons cattle, kills pets and has infected the 2012 corn crop, rendering significant portions of the harvest unfit for consumption. Whereas the deadly organism mainly affects countries like China and developing African nations, many U.S. states have experienced an increase in corn contamination since 2011. Farmers are likely to see more of the carcinogen as temperatures...

Global food crisis will worsen as heatwaves damage crops, research finds
2013-01-13 19:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The world's food crisis, where 1 billion people are already going hungry and a further 2 billion people will be affected by 2050, is set to worsen as increasing heatwaves reverse the rising crop yields seen over the last 50 years, according to new research. Severe heatwaves, such as those currently seen in Australia, are expected to become many times more likely in coming decades due to climate change. Extreme heat led to 2012 becoming the hottest year in the US on record and the worst corn crop...

Lower nitrogen losses with perennial biofuel crops
2013-01-10 18:45:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Perennial biofuel crops such as miscanthus, whose high yields have led them to be considered an eventual alternative to corn in producing ethanol, are now shown to have another beneficial characteristic -- the ability to reduce the escape of nitrogen in the environment. In a 4-year University of Illinois study that compared miscanthus, switchgrass, and mixed prairie species to typical corn-corn-soybean rotations, each of the perennial crops were highly efficient at reducing nitrogen losses, with...

What Cover Crops Can Do
2013-01-01 00:55:00| Corn & Soybean Digest
Theyre just one tool this Indiana farmer uses to guard topsoil and boost soil health. By Dean Houghton During 2012s long, hot summer, Roger Wenning got a firsthand look at how a little soil residue can go a long way to add resilience to a crop. On May 14, the Greensburg, Ind., farmer no-tilled corn into a field that had been in a ryegrass/crimson clover cover crop over the winter. Since this was a high population study, he used a twin-row planter to seed at a population of either 39,000 or 45,000 seeds/acre. read more
