According to a recent state report, the number of migrant and seasonal workers in Michigan has increased 7.3% since 2006. Despite the increase in the number of workers, the Michigan Farm Bureau recently reported that farmers have not been able to find enough help to keep up with the growing industry and their crops. Those involved are blaming the nation's immigration policies, weather patterns, the recession and industry changes. Some farmers have had to leave crops in the field due to the lack of help.
