摘要：Prices for corn, soybeans, wheat, and oats grown "organically" and "conventionally" are compared for the years 1995 through 2003. Conventional prices are those compiled by the USDA's National Agricultural Statistics Service, and organic prices come from the Organic Business News Organic Commodity Prices, through Hotline Printing and Publishing. Ratios of organic-to-conventional prices for both South Dakota and the U.S. are shown for each of the nine years.
