Migrant workers pick, separate, and process sweet potatoes at Kirby Farms in Mechanicsville, VA on Friday, Sept. 20, 2013. 200 acres of the farm are devoted to eggplant, spinach, beets, tomato, jalapeno peppers, melons and a variety of greens. Soybeans and small grain are grown on the remaining 300 acres. Using rotational crop practices allows Kirby Farms to double and triple crop yields. Wholesalers, who buy from this farm, sell the produce to major supermarkets in the Mid-Atlantic region, from North Carolina to Maryland. Restaurants in the local area prepare and serve the local bought produce to patrons in the Richmond, VA metropolitan area.
