Organic shift would cut GHG in crop production, Canadian researchers conclude

Large-scale environmental benefits can be achieved by a wholesale conversion of Canadian corn, wheat, soy and canola production to organic farming methods, say researchers at Dalhousie University’s School for Resource and Environmental Studies, Faculty of Management.
 
“We estimate that such a conversion would result in a 4.8 million tonne reduction in total green house gas emissions annually,” said Nathan Pelletier, lead researcher.  “Such a potential reduction is incredibly important given the enormous toll that climate change is likely to have on human societies and ecosystems.” The study found the organic improvements were heavily influenced by the energy demand and emissions associated with conventional nitrogen fertilizers.
