tailieunhanh - The Sustainability of Organic Grain Production on the Canadian Prairies—A Review

Demand for organically produced food products is increasing rapidly in North America, driven by a perception that organic agriculture results in fewer negative environmental impacts and yields greater benefits for human health than conventional systems. Despite the increasing interest in organic grain production on the Canadian Prairies, a number of challenges remain to be addressed to ensure its long-term sustainability. In this review, we summarize Western Canadian research into organic crop production and evaluate its agronomic, environmental, and economic sustainability. . | Sustainability 2010 2 1016-1034 doi su2041016 OPEN ACCESS sustainability ISSN 2071-1050 journal sustainability Review The Sustainability of Organic Grain Production on the Canadian Prairies A Review Crystal Snyder and Dean Spaner Department of Agricultural Food Nutritional Science 4-10 Agriculture Forestry Centre University of Alberta Edmonton Alberta T6G 2P5 Canada E-Mail Author to whom correspondence should be addressed E-Mail Tel. 1-780-492-2328 Fax 1-780-492-4265.
