摘要：	To provide information on Iowa grain producer flows, Iowa State University, the Iowa Department of Transportation, the Iowa Department of Agriculture and Land Stewardship, and the Iowa Agricultural Statistics cooperatively conducted a survey of how and where Iowa grain producers ship their 1994-95 corn and soybean sales. The producer grain flow survey data were collected by questionnaire from a random sample of farm operators maintained by the Iowa Agricultural Statistics. the 3,501 questionnaires were mailed by Iowa Agriculture Statistics on August 17, 1995. The single mailing yielded 1,510 useable responses; 42.8 percent of those sampled returned useable questionnaires.
