摘要:Since the introduction of genetically modified (GM) crops, the commodity grain system has been under pressure to segregate GM and non-GM crops. Starting at the level of the grain handler, members of the grain supply chain have successfully used quality assurance and identity preservation programs to segregate non-GM crops. Producers delivering high value, identity preserved crops have become interested in implementing these quality management systems at the farm level. We conduct a cost-benefit analysis that shows that quality assurance program may be profitable for producers, depending on their farm size and equipment management strategy.
