摘要：This report is divided into two sections. The first part reports the statewide results for each of five surveyed groups: Iowa grain marketers, Iowa grain handlers, Iowa corn processors, Iowa soybean processors, and Iowa biodiesel producers. The state-level results provide a general idea of the grain and biofuel flows that occurred and the transportation that was utilized in the biofuel-boom era. In order to gain further insights into the regional level data, we present the survey results of grain marketers and handlers in each crop reporting district (CRD) in the second part of the report.
